‘Stop pretending’ there’s a magic formula to weight loss
Is there a diet or weight-loss program out there that doesn’t work for those who stick with it during its first 12 weeks?
Truly, the world’s most backwards, upside-down, anti-science, nonsensical diets work over the short haul, fueled by the fact that short-term suffering for weight loss is a skill set that humanity has assiduously cultivated for at least the past 100 years. We’re really good at it!
It’s the keeping the weight off, though, that’s the hitch. Which leads me to the question, why are medical journals, even preeminent nonpredatory ones, publishing 12-week weight-loss program studies as if they have value? And does anyone truly imagine that after over 100 years of trying, there’ll be a short-term diet or program that’ll have the durable, reproducible results that no other short-term diet or program ever has?
Take this study published by Obesity: “Pragmatic implementation of a fully automated online obesity treatment in primary care.” It details a 12-week online, automated, weight-loss program that led completers to lose the roughly 5% of weight that many diets and programs see lost over their first 12 weeks. By its description, aside from its automated provision, the program sounds like pretty much the same boilerplate weight management advice and recommendations that haven’t been shown to lead large numbers of people to sustain long-term weight loss.
Participants were provided with weekly lessons which no doubt in some manner told them that high-calorie foods had high numbers of calories and should be minimized, along with other weight-loss secrets. Users were to upload weekly self-monitored weight, energy intake, and exercise minutes and were told to use a food diary. Their goal was losing 10% of their body weight by consuming 1,200-1,500 calories per day if they weighed less than 250 pounds (113 kg) and 1,500-1,800 calories if they weighed more than 250 pounds, while also telling them to aim for 200 minutes per week of moderate- to vigorous-intensity physical activity.
What was found was wholly unsurprising. Perhaps speaking to the tremendous and wide-ranging degrees of privilege that are required to prioritize intentional behavior change in the name of health, 79% of those who were given a prescription for the program either didn’t start it or stopped it before the end of the first week.
Of those who actually started the program and completed more than 1 week, despite having been selected as appropriate and interested participants by their physicians, only 20% watched all of the automated programs’ video lessons while only 32% actually bothered to submit all 12 weeks of weight data. Of course, the authors found that those who watched the greatest number of videos and submitted the most self-reported weights lost more weight and ascribed that loss to the program. What the authors did not entertain was the possibility that those who weren’t losing weight, or who were gaining, might simply be less inclined to continue with a program that wasn’t leading them to their desired outcomes or to want to submit their lack of loss or gains.
Short-term weight-loss studies help no one and when, as in this case, the outcomes aren’t even mediocre, and the completion and engagement rates are terrible, the study is still presented as significant and important. This bolsters the harmful stereotype that weight management is achievable by way of simple messages and generic goals. It suggests that it’s individuals who fail programs by not trying hard enough and that those who do, or who want it the most, will succeed. It may also lead patients and clinicians to second-guess the use of antiobesity medications, the current generation of which lead to far greater weight loss and reproducibility than any behavioral program or diet ever has.
The good news here at least is that the small percentage of participants who made it through this program’s 12 weeks are being randomly assigned to differing 9-month maintenance programs which at least will then lead to a 1-year analysis on the completers.
Why this study was published now, rather than pushed until the 1-year data were available, speaks to the pervasiveness of the toxic weight-biased notion that simple education will overcome the physiology forged over millions of years of extreme dietary insecurity.
Our food environment is a veritable floodplain of hyperpalatable foods, and social determinants of health make intentional behavior change in the name of health an unattainable luxury for a huge swath of the population.

Understanding the relationship between life satisfaction and cognitive decline
Every day, we depend on our working memory, spatial cognition, and processing speed abilities to optimize productivity, interpersonal interactions, and psychological wellbeing. These cognitive functioning indices relate closely with academic and work performance, managing emotions, physical fitness, and a sense of fulfillment in personal and work relationships. They are linked intimately to complex cognitive skills (van Dijk et al., 2020). It is thus imperative to identify modifiable predictors of cognitive functioning in the brain to protect against aging-related cognitive decline and maximize the quality of life.
A decline in life satisfaction can worsen cognitive functioning over long periods via lifestyle factors (e.g., suboptimal diet and nutrition, lack of exercise) (Ratigan et al., 2016). Inadequate engagement in these health-enhancing pursuits could build up inflammation in EF-linked brain areas, thus negatively impacting cognitive functioning in adulthood (Grant et al., 2009). Possible pathways include long-term wear and tear of the hypothalamic-pituitary axis and brain regions linked to executive functioning (Zainal and Newman, 2022a). These processes may deteriorate working memory, spatial cognition, and processing speed across time.
Similarly, it is plausible that a reduction in cognitive functioning may lead to a long-term decrease in life satisfaction. Working memory, processing speed, spatial cognition, and related capacities are essential to meaningful activities and feelings of gratification in personal and professional relationships and other spheres of health throughout life (Baumeister et al., 2007). These cognitive functioning markers safeguard against reduced life satisfaction by facilitating effective problem-solving, and choices (Swanson and Fung, 2016). For example, stronger working memory, processing speed, and related domains coincided with better tolerance for stress and trading off immediate rewards for long-term values and life goals (Hofmann et al., 2012). Therefore, reduction in cognitive functioning abilities could precede a future decline in life satisfaction.
Nonetheless, the literature on this topic has several limitations. Most of the studies have been cross-sectional (i.e., across a single time-point) and thus do not permit inferences between cause and effect (e.g., Toh et al., 2020). Also, most studies used statistical methods that did not differentiate between between-person (trait-like individual differences) and within-person (state-like) relations. Distinguishing within- and between-person relations is necessary because they may vary in magnitude and direction. The preceding theories emphasize change-to-future change relations within persons rather than between persons (Wright and Woods, 2020).
Clinical implications
Our recent work (Zainal and Newman, 2022b) added to the literature by using an advanced statistical method to determine the relations between change in life satisfaction and future change in cognitive functioning domains within persons. The choice of an advanced statistical technique minimizes biases due to the passage of time and assessment unreliability. It also adjusts for between-person effects (Klopack and Wickrama, 2020). Improving understanding of the within-person factors leading to the deterioration of cognitive functioning and life satisfaction is crucial given the rising rates of psychiatric and neurocognitive illnesses (Cui et al., 2020). Identifying these changeable risk factors can optimize prevention, early detection, and treatment approaches.
Specifically, we analyzed the publicly available Swedish Adoption/Twin Study of Aging (SATSA) dataset (Petkus et al., 2017). Their dataset comprised 520 middle- to older-aged twin adults without dementia. Participants provided data across 23 years with five time points. Each time lag ranged from 3 to 11 years. The analyses demonstrated that greater decreases in life satisfaction predicted larger future declines in processing speed, verbal working memory, and spatial cognition. Moreover, declines in verbal working memory and processing speed predicted a reduction in life satisfaction. However, change in spatial awareness did not predict change in life satisfaction.
Our study offers multiple theoretical perspectives. Scar theories propose that decreased life satisfaction and related mental health problems can compromise working memory, processing speed, and spatial cognition in the long term. This scarring process occurs through the buildup of allostatic load, such as increased biomarkers of chronic stress (e.g., cortisol) and inflammation (e.g., interleukin-6, C-reactive protein) (Fancourt and Steptoe, 2020; Zainal and Newman, 2021a). Also, findings suggest the importance of executive functioning domains to attain desired milestones and aspirations to enhance a sense of fulfillment (Baddeley, 2013; Toh and Yang, 2020). Reductions in these cognitive functioning capacities could, over time, adversely affect the ability to engage in daily living activities and manage negative moods.
Limitations of our study include the lack of a multiple-assessment approach to measuring diverse cognitive functioning domains. Also, the absence of cognitive self-reports is a shortcoming since perceived cognitive difficulties might not align with performance on cognitive tests. Relatedly, future studies should administer cognitive tests that parallel and transfer to everyday tasks. However, our study’s strengths include the robust findings across different intervals between study waves, advanced statistics, and the large sample size.
If future studies replicate a similar pattern of results, the clinical applications of this study merit attention. Mindfulness-based interventions can promote working memory, sustained awareness, and spatial cognition or protect against cognitive decline (Jha et al., 2019; Zainal and Newman, 2021b). Further, clinical science can profit from exploring cognitive-behavioral therapies to improve adults’ cognitive function or life satisfaction (Sok et al., 2021).

Every day, we depend on our working memory, spatial cognition, and processing speed abilities to optimize productivity, interpersonal interactions, and psychological wellbeing. These cognitive functioning indices relate closely with academic and work performance, managing emotions, physical fitness, and a sense of fulfillment in personal and work relationships. They are linked intimately to complex cognitive skills (van Dijk et al., 2020). It is thus imperative to identify modifiable predictors of cognitive functioning in the brain to protect against aging-related cognitive decline and maximize the quality of life.
A decline in life satisfaction can worsen cognitive functioning over long periods via lifestyle factors (e.g., suboptimal diet and nutrition, lack of exercise) (Ratigan et al., 2016). Inadequate engagement in these health-enhancing pursuits could build up inflammation in EF-linked brain areas, thus negatively impacting cognitive functioning in adulthood (Grant et al., 2009). Possible pathways include long-term wear and tear of the hypothalamic-pituitary axis and brain regions linked to executive functioning (Zainal and Newman, 2022a). These processes may deteriorate working memory, spatial cognition, and processing speed across time.
Similarly, it is plausible that a reduction in cognitive functioning may lead to a long-term decrease in life satisfaction. Working memory, processing speed, spatial cognition, and related capacities are essential to meaningful activities and feelings of gratification in personal and professional relationships and other spheres of health throughout life (Baumeister et al., 2007). These cognitive functioning markers safeguard against reduced life satisfaction by facilitating effective problem-solving, and choices (Swanson and Fung, 2016). For example, stronger working memory, processing speed, and related domains coincided with better tolerance for stress and trading off immediate rewards for long-term values and life goals (Hofmann et al., 2012). Therefore, reduction in cognitive functioning abilities could precede a future decline in life satisfaction.
Nonetheless, the literature on this topic has several limitations. Most of the studies have been cross-sectional (i.e., across a single time-point) and thus do not permit inferences between cause and effect (e.g., Toh et al., 2020). Also, most studies used statistical methods that did not differentiate between between-person (trait-like individual differences) and within-person (state-like) relations. Distinguishing within- and between-person relations is necessary because they may vary in magnitude and direction. The preceding theories emphasize change-to-future change relations within persons rather than between persons (Wright and Woods, 2020).
Clinical implications
Our recent work (Zainal and Newman, 2022b) added to the literature by using an advanced statistical method to determine the relations between change in life satisfaction and future change in cognitive functioning domains within persons. The choice of an advanced statistical technique minimizes biases due to the passage of time and assessment unreliability. It also adjusts for between-person effects (Klopack and Wickrama, 2020). Improving understanding of the within-person factors leading to the deterioration of cognitive functioning and life satisfaction is crucial given the rising rates of psychiatric and neurocognitive illnesses (Cui et al., 2020). Identifying these changeable risk factors can optimize prevention, early detection, and treatment approaches.
Specifically, we analyzed the publicly available Swedish Adoption/Twin Study of Aging (SATSA) dataset (Petkus et al., 2017). Their dataset comprised 520 middle- to older-aged twin adults without dementia. Participants provided data across 23 years with five time points. Each time lag ranged from 3 to 11 years. The analyses demonstrated that greater decreases in life satisfaction predicted larger future declines in processing speed, verbal working memory, and spatial cognition. Moreover, declines in verbal working memory and processing speed predicted a reduction in life satisfaction. However, change in spatial awareness did not predict change in life satisfaction.
Our study offers multiple theoretical perspectives. Scar theories propose that decreased life satisfaction and related mental health problems can compromise working memory, processing speed, and spatial cognition in the long term. This scarring process occurs through the buildup of allostatic load, such as increased biomarkers of chronic stress (e.g., cortisol) and inflammation (e.g., interleukin-6, C-reactive protein) (Fancourt and Steptoe, 2020; Zainal and Newman, 2021a). Also, findings suggest the importance of executive functioning domains to attain desired milestones and aspirations to enhance a sense of fulfillment (Baddeley, 2013; Toh and Yang, 2020). Reductions in these cognitive functioning capacities could, over time, adversely affect the ability to engage in daily living activities and manage negative moods.
Limitations of our study include the lack of a multiple-assessment approach to measuring diverse cognitive functioning domains. Also, the absence of cognitive self-reports is a shortcoming since perceived cognitive difficulties might not align with performance on cognitive tests. Relatedly, future studies should administer cognitive tests that parallel and transfer to everyday tasks. However, our study’s strengths include the robust findings across different intervals between study waves, advanced statistics, and the large sample size.
If future studies replicate a similar pattern of results, the clinical applications of this study merit attention. Mindfulness-based interventions can promote working memory, sustained awareness, and spatial cognition or protect against cognitive decline (Jha et al., 2019; Zainal and Newman, 2021b). Further, clinical science can profit from exploring cognitive-behavioral therapies to improve adults’ cognitive function or life satisfaction (Sok et al., 2021).

Reliably solving complex problems
The James Webb Space Telescope (JWST) is an engineering marvel. Costing over $10 billion, it should be. The project cost overrun was 900%. The launch was delayed by more than a decade. The Human Genome Project from 1990 to 2003 was completed slightly ahead of schedule and for less than the $4-$5 billion original estimates. This HGP success story is partly because of private entrepreneurial involvement. The Superconducting Super Collider in Texas spent $2 billion but never got off the ground. Successfully shepherding huge public projects like these involves the art of politics and management as well as science.
Whatever the earlier missteps, the JWST project is now performing above expectations. It has launched, taken up residence a million miles from Earth, deployed its mirrors (a process that had more than 300 possible single points of failure, any one of which would reduce the thing to scrap metal), and been calibrated. The JWST has even been dented by a micrometeoroid – sort of like a parking lot ding on the door of your brand new car. The first images are visually amazing and producing new scientific insights. This is a pinnacle of scientific achievement.
What characteristics enable such an achievement? How do we foster those same characteristics in the practice of medicine and medical research? Will the success of the JWST increase and restore the public’s trust in science and scientists?
After all the bickering over vaccines and masks for the past 2+ years, medical science could use a boost. The gravitas of scientists, and indeed all experts, has diminished over the 5 decades since humans walked on the moon. It has been harmed by mercenary scientists who sought to sow doubt about whether smoking caused cancer and whether fossil fuels created climate change. No proof was needed, just doubt.
The trust in science has also been harmed by the vast amount of published medical research that is wrong. An effort was made 20 years ago to rid research of the bias of taking money from drug companies. To my observation, that change produced only a small benefit that has been overwhelmed by the unintended harms. The large, well-funded academic labs of full-time researchers have been replaced with unfunded, undertrained, and inadequately supported part-time junior faculty trying to publish enough articles to be promoted. In my opinion, this change is worse than funding from Big Pharma. (Disclosure – I worked in industry prior to graduate school.)
The pressure to publish reduces skepticism, so more incorrect data are published. The small size of these amateur studies produces unconvincing conclusions that feed an industry of meta-analysis that tries to overcome the deficiencies of the individual studies. This fragmented, biased approach is not how you build, launch, deploy, and operate the JWST, which requires very high reliability.
This approach is not working well for pediatrics either. I look at the history of the recommended workup of the febrile young infant from the 1980s until today. I see constant changes to the guidelines but no real progress toward a validated, evidence-based approach. A similar history is behind treatment of neonatal hyperbilirubinemia. In the 1994 publication, there was a movement toward being less aggressive. The 2004 and 2009 editions increased the frequency of screening and phototherapy. Now, the 2022 guidelines have moved in the direction we were headed in the 1990s. The workup of infants and children with possible urinary tract infections has undergone a similar trajectory. So has the screening for neonatal herpes infections. The practice changes are more like Brownian motion than real progress. This inconsistency has led me to be skeptical of the process the American Academy of Pediatrics uses to create guidelines.
Part of solving complex problems is allowing all stakeholders’ voices to be heard. On Jan. 28, 1986, seconds after liftoff, the space shuttle Challenger exploded. In the aftermath, it was determined that some engineers had expressed concern about the very cold weather that morning. The rubber in the O-ring would not be as flexible as designed. Their objection was not listened to. The O-ring failed, the fuel tank exploded, and the ship and crew were lost. It is a lesson many engineers of my generation took to heart. Do not suppress voices.
For example, 1 year ago (September 2021), the Royal Australian and New Zealand College of Psychiatrists published a position statement, “Recognising and addressing the mental health needs of people experiencing gender dysphoria/gender incongruence.” The statement expressed concern about the marked increase in incidence of rapid-onset gender dysphoria and therefore urged more thorough assessment by psychiatry before embarking on puberty-blocking therapies. The RANZCP position is at variance with recent trends in the United States. The topic was censored at the 2021 AAP national conference. Lately, I have heard the words disinformation and homophobic used to describe my RANZCP colleagues. I have been comparing AAP, Britain’s National Institute for Health and Care Excellence, and Royal Children’s Hospital Melbourne guidelines for 20 years. The variation is enlightening. I do not know the correct answer to treating gender dysphoria, but I know suppressing viewpoints and debate leads to exploding spaceships.

Estrogen replacement therapy in endometrial cancer survivors
In the United States, uterine cancer is the fourth most common cancer among women, behind breast, lung/bronchus, and colorectal cancer. There are expected to be almost 66,000 new cases of uterine cancer in 2022.1 The majority of uterine cancers are endometrioid in histology and tend to be low grade, diagnosed at an early stage, and have a good prognosis. While our molecular understanding of endometrial cancers (EC) has changed significantly in recent years, low-grade endometrioid adenocarcinomas have historically been described as type 1 ECs. Type 1 ECs are typically caused by excess estrogen exposure (often unopposed or lacking progesterone protection) and are preceded by endometrial hyperplasia. Excess estrogen can come from exogenous sources (such as unopposed estrogen replacement therapy or tamoxifen, a commonly used treatment in estrogen receptor–positive breast cancer that acts as an estrogen agonist in the endometrium in postmenopausal patients) or endogenous ones (such as obesity).
Peripheral adipose tissue converts androgens into estrogens; paired with the decreased levels of sex hormone–binding globulin seen in obesity, there is more unbound or free serum estrogen (specifically estradiol) in obese women. Estrogen acts on the endometrium to cause proliferation and, if unopposed or imbalanced in relation to progesterone exposure, can ultimately lead to hyperplasia and malignancy.
If excess and unopposed estrogen exposure are major risk factors for the development of EC, is it safe to consider estrogen replacement therapy (ERT) in patients after EC treatment?
The short answer is the data are limited, but in a patient with a history of low-risk early-stage EC who undergoes appropriate counseling, it is likely safe to consider ERT.
Among EC survivors, there has been only one prospective randomized controlled trial that assessed the effect of recurrence rate and survival in women on ERT after EC treatment.2 Patients with stage I or occult stage II endometrial adenocarcinoma treated with at least a total hysterectomy and bilateral salpingo-oophorectomy were randomized to ERT versus placebo for 3 years of treatment, with therapy starting once recovered and within 20 weeks after surgery. Trial participation required an indication for ERT, such as vasomotor symptoms, vaginal atrophy, or increased risk of cardiovascular disease or osteoporosis.
The trial accrued 1,236 patients, falling short of its goal of 2,108 patients after enrollment decreased following the publication of the Women’s Health Initiative results in 2002. This publication prompted a review of the ERT study protocol that found that between decreased accrual and lower than expected recurrence rate, goal accrual would be impossible. Of those enrolled, participants were overwhelmingly white (84%-85%), 41-70 years old (80%-82%), and had stage IA or IB disease (88%). Median follow-up was almost 3 years.
Twenty-six (2.1%) patients experienced cancer recurrence, with similar rates in both groups. Three-year progression-free and overall survival were high overall among all study participants (94.8% and 96.5%). Unfortunately, because the study was closed early, definitive conclusions about the noninferiority of ERT versus placebo regarding oncologic outcomes in early-stage endometrial adenocarcinoma could not be made.
A subsequent meta-analysis looked at the effect of hormone therapy (HT) on recurrence rate in EC survivors.3 Five observational studies were included along with the previously discussed randomized controlled trial. Among 1,975 participants across six studies, there were cancer recurrences in 19 of 896 (2.1%) HT users and 64 of 1,079 (5.9%) controls. HT did not negatively affect cancer recurrence or overall survival. There was significant heterogeneity between studies as to dosing, duration, and type of HT given (some used estrogen-only replacement, others used estrogen and progesterone replacement, and some used both estrogen only and the combination of estrogen and progesterone replacement). Among the five nonrandomized studies included, a protective effect of combined HT on EC recurrence was noted. One study included patients with stage III disease, but only four patients received HT in this cohort.
Given the data we have, ERT does not appear to significantly affect oncologic outcomes in low-risk, early-stage EC survivors. We do not have data to support this same assertion in more advanced, high-risk disease. Before initiation of any ERT in an EC survivor, there should be a detailed discussion to weigh the risks and benefits of starting therapy. The goal of treatment should be to use the lowest dose of ERT possible to treat symptoms, with planned surveillance visits for symptom check-in and assessment of readiness to start tapering treatment.

There are no randomized trials assessing the safety of vaginal estrogen preparations or their effect on oncologic outcomes in EC survivors. Observational data from the Women’s Health Initiative showed no increased risk of endometrial cancer in patients who used vaginal estrogen with an intact uterus.4 A recently published retrospective study among 244 gynecologic cancer survivors found low rates of disease recurrence and adverse outcomes among women who used vaginal estrogen for genitourinary symptoms.5 Among EC survivors, the incidence of recurrence was 2.4% for patients with stage I/II disease and 4.3% for stage III/IV disease, with a median follow-up of 80.2 months. While there appears to be some systemic absorption with vaginal estrogen use, this can be quite challenging to measure because of the current sensitivity of serum estradiol and estrone assays. Given the significantly lower serum levels with vaginal estrogen preparations compared with ERT, vaginal estrogen use appears to be safe in EC survivors.

In the United States, uterine cancer is the fourth most common cancer among women, behind breast, lung/bronchus, and colorectal cancer. There are expected to be almost 66,000 new cases of uterine cancer in 2022.1 The majority of uterine cancers are endometrioid in histology and tend to be low grade, diagnosed at an early stage, and have a good prognosis. While our molecular understanding of endometrial cancers (EC) has changed significantly in recent years, low-grade endometrioid adenocarcinomas have historically been described as type 1 ECs. Type 1 ECs are typically caused by excess estrogen exposure (often unopposed or lacking progesterone protection) and are preceded by endometrial hyperplasia. Excess estrogen can come from exogenous sources (such as unopposed estrogen replacement therapy or tamoxifen, a commonly used treatment in estrogen receptor–positive breast cancer that acts as an estrogen agonist in the endometrium in postmenopausal patients) or endogenous ones (such as obesity).
Peripheral adipose tissue converts androgens into estrogens; paired with the decreased levels of sex hormone–binding globulin seen in obesity, there is more unbound or free serum estrogen (specifically estradiol) in obese women. Estrogen acts on the endometrium to cause proliferation and, if unopposed or imbalanced in relation to progesterone exposure, can ultimately lead to hyperplasia and malignancy.
If excess and unopposed estrogen exposure are major risk factors for the development of EC, is it safe to consider estrogen replacement therapy (ERT) in patients after EC treatment?
The short answer is the data are limited, but in a patient with a history of low-risk early-stage EC who undergoes appropriate counseling, it is likely safe to consider ERT.
Among EC survivors, there has been only one prospective randomized controlled trial that assessed the effect of recurrence rate and survival in women on ERT after EC treatment.2 Patients with stage I or occult stage II endometrial adenocarcinoma treated with at least a total hysterectomy and bilateral salpingo-oophorectomy were randomized to ERT versus placebo for 3 years of treatment, with therapy starting once recovered and within 20 weeks after surgery. Trial participation required an indication for ERT, such as vasomotor symptoms, vaginal atrophy, or increased risk of cardiovascular disease or osteoporosis.

Why our brains wear out at the end of the day
The transcript has been edited for clarity.
Welcome to Impact Factor, your weekly dose of commentary on a new medical study. I’m Dr. F. Perry Wilson of the Yale School of Medicine.
Once again, we’re doing an informal journal club to talk about a really interesting study, “A Neuro-metabolic Account of Why Daylong Cognitive Work Alters the Control of Economic Decisions,” that just came out. It tries to answer the question of why our brains wear out. I’m going to put myself in the corner here. Let’s walk through this study, which appears in Current Biology, by lead author Antonius Wiehler from Paris.
The big question is what’s going on with cognitive fatigue. If you look at chess players who are exerting a lot of cognitive effort, it’s well documented that over hours of play, they get worse and make more mistakes. It takes them longer to make decisions. The question is, why?
Why does your brain get tired?
To date, it’s been a little bit hard to tease that out. Now, there is some suggestion of what is responsible for this. The cognitive control center of the brain is probably somewhere in the left lateral prefrontal cortex (LLPC).
The prefrontal cortex is responsible for higher-level thinking. It’s what causes you to be inhibited. It gets shut off by alcohol and leads to impulsive behaviors. The LLPC, according to functional MRI studies, has reduced activity as people become more and more cognitively fatigued. The LLPC helps you think through choices. As you become more fatigued, this area of the brain isn’t working as well. But why would it not work as well? What is going on in that particular part of the brain? It doesn’t seem to be something simple, like glucose levels; that’s been investigated and glucose levels are pretty constant throughout the brain, regardless of cognitive task. This paper seeks to tease out what is actually going on in the LLPC when you are becoming cognitively tired.
They did an experiment where they induced cognitive fatigue, and it sounds like a painful experiment. For more than 6 hours, volunteers completed sessions during which they had to perform cognitive switching tasks. Investigators showed participants a letter, in either red or green, and the participant would respond with whether it was a vowel or a consonant or whether it was a capital or lowercase letter, based on the color. If it’s red, say whether it’s a consonant or vowel. If it’s green, say whether it’s upper- or lowercase.
It’s hard, and doing it for 6 hours is likely to induce a lot of cognitive fatigue. They had a control group as well, which is really important here. The control group also did a task like this for 6 hours, but for them, investigators didn’t change the color as often – perhaps only once per session. For the study group, they were switching colors back and forth quite a lot. They also incorporated a memory challenge that worked in a similar way.
So, what are the readouts of this study? They had a group who went through the hard cognitive challenge and a group who went through the easy cognitive challenge. They looked at a variety of metrics. I’ll describe a few.
The first is performance decrement. Did they get it wrong? What percentage of the time did the participant say “consonant” when they should have said “lowercase?”
You can see here that the hard group did a little bit worse overall. It was harder, so they don’t do as well. That makes sense. But both groups kind of waned over time a little bit. It’s not as though the hard group declines much more. The slopes of those lines are pretty similar. So, not very robust findings there.
What about subjective fatigue? They asked the participants how exhausted they were from doing the tasks.
Both groups were worn out. It was a long day. There was a suggestion that the hard group became worn out a little bit sooner, but I don’t think this achieves statistical significance. Everyone was getting tired by hour 6 here.
What about response time? How quickly could the participant say “consonant,” “vowel,” “lowercase,” or “uppercase?”
The hard group took longer to respond because it was a harder task. But over time, the response times were pretty flat.
So far there isn’t a robust readout that would make us say, oh, yeah, that is a good marker of cognitive fatigue. That’s how you measure cognitive fatigue. It’s not what people say. It’s not how quick they are. It’s not even how accurate they are.
But then the investigators got a little bit clever. Participants were asked to play a “would you rather” game, a reward game. Here are two examples.
Would you rather:
- Have a 25% chance of earning $50 OR a 95% chance of earning $17.30?
- Earn $50, but your next task session will be hard or earn $40 and your next task session will be easy?
Participants had to figure out the better odds – what should they be choosing here? They had to tease out whether they preferred lower cost lower-risk choices – when they are cognitively fatigued, which has been shown in prior studies.
This showed a pretty dramatic difference between the groups in terms of the low-cost bias – how much more likely they were to pick the low-cost, easier choice as they became more and more cognitively fatigued. The hard group participants were more likely to pick the easy thing rather than the potentially more lucrative thing, which is really interesting when we think about how our own cognitive fatigue happens at the end of a difficult workday, how you may just be likely to go with the flow and do something easy because you just don’t have that much decision-making power left.
It would be nice to have some objective physiologic measurements for this, and they do. This is pupil dilation.
When you’re paying attention to something, your pupils dilate a little bit. They were able to show that as the hard group became more and more fatigued, pupil dilation sort of went away. In fact, if anything, their pupils constricted a little bit. But basically there was a significant difference here. The easy group’s pupils were still fine; they were still dilating. The hard group’s pupils got more sluggish. This is a physiologic correlate of what’s going on.
But again, these are all downstream of whatever is happening in the LLPC. So the real meat of this study is a functional MRI analysis, and the way they did this is pretty clever. They were looking for metabolites in the various parts of the brain using a labeled hydrogen MRI, which is even fancier than a functional MRI. It’s like MRI spectroscopy, and it can measure the levels of certain chemicals in the brain. They hypothesized that if there is a chemical that builds up when you are tired, it should build up preferentially in the LLPC.
Whereas in the rest of the brain, there shouldn’t be that much difference because we know the action is happening in the LLPC. The control part of the brain is a section called V1. They looked at a variety of metabolites, but the only one that behaved the way they expected was glutamate and glutamic acid (glutamate metabolites). In the hard group, the glutamate is building up over time, so there is a higher concentration of glutamate in the LLPC but not the rest of the brain. There is also a greater diffusion of glutamate from the intracellular to the extracellular space, which suggests that it’s kind of leaking out of the cells.
So the signal here is that the thing that’s impacting that part of the brain is this buildup of glutamate. To tie this together, they showed in the scatterplot the relationship between the increase in glutamate and the low-cost bias from the decision fatigue example.
It’s not the strongest correlation, but it is statistically significant that the more glutamate in your LLPC, the more likely you are to just take the easy decision as opposed to really thinking things through. That is pretty powerful. It’s telling us that your brain making you fatigued, and making you less likely to continue to use your LLPC, may be a self-defense mechanism against a buildup of glutamate, which may be neurotoxic. And that’s a fascinating bit of homeostasis.
Of course, it makes you wonder how we might adjust glutamate levels in the brain, although maybe we should let the brain be tired if the brain wants to be tired. It reminds me of that old Far Side cartoon where the guy is raising his hand and asking: “Can I be excused? My brain is full.” That is essentially what’s happening. This part of your brain is becoming taxed and building up glutamate. There’s some kind of negative feedback loop. The authors don’t know what the receptor pathway is that down-regulates that part of the brain based on the glutamate buildup, but some kind of negative feedback loop is saying, okay, give this part of the brain a rest. Things have gone on too far here.
It’s a fascinating study, although it’s not clear what we can do with this information. It’s not clear whether we can manipulate glutamate levels in this particular part of the brain or not. But it’s nice to see some biologic correlates of a psychological phenomenon that is incredibly well described – the phenomenon of decision fatigue. I think we all feel it at the end of a hard workday. If you’ve been doing a lot of cognitively intensive tasks, you just don’t have it in you anymore. And maybe the act of a good night’s sleep is clearing out some of that glutamate in the LLPC, which lets you start over and make some good decisions again. So I hope you all make some good decisions and keep your glutamate levels low. And I’ll see you next time.

It’s a fascinating study, although it’s not clear what we can do with this information. It’s not clear whether we can manipulate glutamate levels in this particular part of the brain or not. But it’s nice to see some biologic correlates of a psychological phenomenon that is incredibly well described – the phenomenon of decision fatigue. I think we all feel it at the end of a hard workday. If you’ve been doing a lot of cognitively intensive tasks, you just don’t have it in you anymore. And maybe the act of a good night’s sleep is clearing out some of that glutamate in the LLPC, which lets you start over and make some good decisions again. So I hope you all make some good decisions and keep your glutamate levels low. And I’ll see you next time.

Welcome to Impact Factor, your weekly dose of commentary on a new medical study. I’m Dr. F. Perry Wilson of the Yale School of Medicine.
Once again, we’re doing an informal journal club to talk about a really interesting study, “A Neuro-metabolic Account of Why Daylong Cognitive Work Alters the Control of Economic Decisions,” that just came out. It tries to answer the question of why our brains wear out. I’m going to put myself in the corner here. Let’s walk through this study, which appears in Current Biology, by lead author Antonius Wiehler from Paris.
The big question is what’s going on with cognitive fatigue. If you look at chess players who are exerting a lot of cognitive effort, it’s well documented that over hours of play, they get worse and make more mistakes. It takes them longer to make decisions. The question is, why?
Why does your brain get tired?
To date, it’s been a little bit hard to tease that out. Now, there is some suggestion of what is responsible for this. The cognitive control center of the brain is probably somewhere in the left lateral prefrontal cortex (LLPC).
The prefrontal cortex is responsible for higher-level thinking. It’s what causes you to be inhibited. It gets shut off by alcohol and leads to impulsive behaviors. The LLPC, according to functional MRI studies, has reduced activity as people become more and more cognitively fatigued. The LLPC helps you think through choices. As you become more fatigued, this area of the brain isn’t working as well. But why would it not work as well? What is going on in that particular part of the brain? It doesn’t seem to be something simple, like glucose levels; that’s been investigated and glucose levels are pretty constant throughout the brain, regardless of cognitive task. This paper seeks to tease out what is actually going on in the LLPC when you are becoming cognitively tired.
They did an experiment where they induced cognitive fatigue, and it sounds like a painful experiment. For more than 6 hours, volunteers completed sessions during which they had to perform cognitive switching tasks. Investigators showed participants a letter, in either red or green, and the participant would respond with whether it was a vowel or a consonant or whether it was a capital or lowercase letter, based on the color. If it’s red, say whether it’s a consonant or vowel. If it’s green, say whether it’s upper- or lowercase.
It’s hard, and doing it for 6 hours is likely to induce a lot of cognitive fatigue. They had a control group as well, which is really important here. The control group also did a task like this for 6 hours, but for them, investigators didn’t change the color as often – perhaps only once per session. For the study group, they were switching colors back and forth quite a lot. They also incorporated a memory challenge that worked in a similar way.
So, what are the readouts of this study? They had a group who went through the hard cognitive challenge and a group who went through the easy cognitive challenge. They looked at a variety of metrics. I’ll describe a few.
The first is performance decrement. Did they get it wrong? What percentage of the time did the participant say “consonant” when they should have said “lowercase?”
You can see here that the hard group did a little bit worse overall. It was harder, so they don’t do as well. That makes sense. But both groups kind of waned over time a little bit. It’s not as though the hard group declines much more. The slopes of those lines are pretty similar. So, not very robust findings there.
What about subjective fatigue? They asked the participants how exhausted they were from doing the tasks.
Both groups were worn out. It was a long day. There was a suggestion that the hard group became worn out a little bit sooner, but I don’t think this achieves statistical significance. Everyone was getting tired by hour 6 here.
What about response time? How quickly could the participant say “consonant,” “vowel,” “lowercase,” or “uppercase?”
The hard group took longer to respond because it was a harder task. But over time, the response times were pretty flat.
So far there isn’t a robust readout that would make us say, oh, yeah, that is a good marker of cognitive fatigue. That’s how you measure cognitive fatigue. It’s not what people say. It’s not how quick they are. It’s not even how accurate they are.
But then the investigators got a little bit clever. Participants were asked to play a “would you rather” game, a reward game. Here are two examples.
Would you rather:
- Have a 25% chance of earning $50 OR a 95% chance of earning $17.30?
- Earn $50, but your next task session will be hard or earn $40 and your next task session will be easy?
Participants had to figure out the better odds – what should they be choosing here? They had to tease out whether they preferred lower cost lower-risk choices – when they are cognitively fatigued, which has been shown in prior studies.
This showed a pretty dramatic difference between the groups in terms of the low-cost bias – how much more likely they were to pick the low-cost, easier choice as they became more and more cognitively fatigued. The hard group participants were more likely to pick the easy thing rather than the potentially more lucrative thing, which is really interesting when we think about how our own cognitive fatigue happens at the end of a difficult workday, how you may just be likely to go with the flow and do something easy because you just don’t have that much decision-making power left.
It would be nice to have some objective physiologic measurements for this, and they do. This is pupil dilation.
When you’re paying attention to something, your pupils dilate a little bit. They were able to show that as the hard group became more and more fatigued, pupil dilation sort of went away. In fact, if anything, their pupils constricted a little bit. But basically there was a significant difference here. The easy group’s pupils were still fine; they were still dilating. The hard group’s pupils got more sluggish. This is a physiologic correlate of what’s going on.
But again, these are all downstream of whatever is happening in the LLPC. So the real meat of this study is a functional MRI analysis, and the way they did this is pretty clever. They were looking for metabolites in the various parts of the brain using a labeled hydrogen MRI, which is even fancier than a functional MRI. It’s like MRI spectroscopy, and it can measure the levels of certain chemicals in the brain. They hypothesized that if there is a chemical that builds up when you are tired, it should build up preferentially in the LLPC.
Whereas in the rest of the brain, there shouldn’t be that much difference because we know the action is happening in the LLPC. The control part of the brain is a section called V1. They looked at a variety of metabolites, but the only one that behaved the way they expected was glutamate and glutamic acid (glutamate metabolites). In the hard group, the glutamate is building up over time, so there is a higher concentration of glutamate in the LLPC but not the rest of the brain. There is also a greater diffusion of glutamate from the intracellular to the extracellular space, which suggests that it’s kind of leaking out of the cells.
So the signal here is that the thing that’s impacting that part of the brain is this buildup of glutamate. To tie this together, they showed in the scatterplot the relationship between the increase in glutamate and the low-cost bias from the decision fatigue example.
It’s not the strongest correlation, but it is statistically significant that the more glutamate in your LLPC, the more likely you are to just take the easy decision as opposed to really thinking things through. That is pretty powerful. It’s telling us that your brain making you fatigued, and making you less likely to continue to use your LLPC, may be a self-defense mechanism against a buildup of glutamate, which may be neurotoxic. And that’s a fascinating bit of homeostasis.
Of course, it makes you wonder how we might adjust glutamate levels in the brain, although maybe we should let the brain be tired if the brain wants to be tired. It reminds me of that old Far Side cartoon where the guy is raising his hand and asking: “Can I be excused? My brain is full.” That is essentially what’s happening. This part of your brain is becoming taxed and building up glutamate. There’s some kind of negative feedback loop. The authors don’t know what the receptor pathway is that down-regulates that part of the brain based on the glutamate buildup, but some kind of negative feedback loop is saying, okay, give this part of the brain a rest. Things have gone on too far here.
It’s a fascinating study, although it’s not clear what we can do with this information. It’s not clear whether we can manipulate glutamate levels in this particular part of the brain or not. But it’s nice to see some biologic correlates of a psychological phenomenon that is incredibly well described – the phenomenon of decision fatigue.

And maybe the act of a good night’s sleep is clearing out some of that glutamate in the LLPC, which lets you start over and make some good decisions again. So I hope you all make some good decisions and keep your glutamate levels low. And I’ll see you next time.

He was a fit man in his 40s. Thick legs. Maybe he was a long-distance walker? The bones of his right arm were more developed than his left – a right-handed thrower. His lower left fibula was fractured from a severely rolled ankle. He carried a walking stick that was glossy in the middle from where he gripped it with his left hand, dragging his bad left foot along. Dental cavities tell the story of his diet: honey, carobs, dates. Carbon 14 dating confirms that he lived during the Chalcolithic period, approximately 6,000 years ago. He was likely a shepherd in the Judean Desert.
Isn’t it amazing how much we can know about another human even across such an enormous chasm of time? If you’d asked me when I was 11 what I wanted to be, I’d have said archaeologist. .
A 64-year-old woman with a 4-cm red, brown shiny plaque on her right calf. She burned it on her boyfriend’s Harley Davidson nearly 40 years ago. She wonders where he is now.
A 58-year-old man with a 3-inch scar on his right wrist. He fell off his 6-year-old’s skimboard. ORIF.
A 40-year-old woman with bilateral mastectomy scars.
A 66-year-old with a lichenified nodule on his left forearm. When I shaved it off, a quarter inch spicule of glass came out. It was from a car accident in his first car, a Chevy Impala. He saved the piece of glass as a souvenir.
A fit 50-year-old with extensive scars on his feet and ankles. “Yeah, I went ‘whistling-in’ on a training jump,” he said. He was a retired Navy Seal and raconteur with quite a tale about the day his parachute malfunctioned. Some well placed live oak trees is why he’s around for his skin screening.
A classic, rope-like open-heart scar on the chest of a thin, young, healthy, flaxen-haired woman. Dissected aorta.
A 30-something woman dressed in a pants suit with razor-thin parallel scars on her volar forearms and proximal thighs. She asks if any laser could remove them.
A rotund, hard-living, bearded man with chest and upper-arm tattoos of flames and nudie girls now mixed with the striking face of an old woman and three little kids: His mom and grandkids. He shows me where the fourth grandkid will go and gives me a bear hug to thank me for the care when he leaves.
Attending to these details shifts us from autopilot to present. It keeps us involved, holding our attention even if it’s the 20th skin screening or diabetic foot exam of the day. And what a gift to share in the intimate details of another’s life.

Postpartum psychosis: Does longitudinal course inform treatment?
The last 15 years have brought increased effort to screen for postpartum psychiatric illness. That’s exceedingly welcome given the morbidity and potential mortality associated with postpartum psychiatric disorders across the country.
From small community hospitals to major academic centers, screening for postpartum depression is part of the clinical fabric of routine obstetrical care. There is a growing appreciation for the complexity of perinatal psychiatric illness, particularly with respect to the commingling of both mood and anxiety disorders during the postpartum period. However, willingness to treat and appreciation of the urgency to treat with both pharmacologic and nonpharmacologic interventions can vary. For women who suffer from postpartum depression and their families, there are real-world implications of both treating and failing to treat this illness, and there is an urgent need to really help these women “climb out of the darkness” that is and defines postpartum depression.
Less common but of great clinical importance is postpartum psychosis, which occurs in approximately 1 in 1,000-2,000 women based on estimates from several studies. As noted in previous columns, the presentation is a dramatic one, with the typical onset of psychotic symptoms in the first days to weeks post partum. The disorder typically has a mood component and is not an exacerbation of underlying chronic psychotic illness. While there have been few systematic treatment studies, the clinical consensus is treatment usually includes hospitalization to ensure the safety of both the patient and infant. Use of medications, including mood stabilizers, antipsychotics, and benzodiazepines may be appropriate when expeditious treatment is needed.
Appropriate treatment by informed clinical staff is essential, as untreated or incompletely treated postpartum psychosis with its attendant morbidity and potential mortality is a very real concern. As I speak with women across the country with histories of postpartum psychosis, I’m often told of the difficult exchanges that women and their partners have at EDs in various clinical settings where diagnosis was delayed, or treatment was incomplete because of staff without expertise in postpartum psychosis management.
Another dilemma that patients and clinicians face after acute treatment is treatment duration, which is derived from how we conceptualize the illness. Even for experts in the area, there is not a consensus on whether postpartum psychosis should be considered as bipolar disorder or whether it is a circumscribed diagnostic entity. This issue has been hotly debated for many years and is one of the reasons why the illness is not included in the DSM classification system.
At Massachusetts General Hospital, we are systematically studying a large cohort of women with histories of postpartum psychosis as part of the MGH Postpartum Psychosis Project to better understand the phenomenology of postpartum psychosis, and also to understand the possible genomic underpinning of the illness. Most recently, we are conducting a neuroimaging study of women with histories of postpartum psychosis, compared with women in a healthy control group. We hope the results of this novel investigation will help to answer whether there is a neural signature identifiable with neuroimaging techniques such as functional MRI, if those findings are similar to other findings of neural circuitry we see in other forms of psychotic illness, or if the illness has a more distinct neural signature.
A question patients and colleagues often ask is what is the long-term nature of postpartum psychosis. If one considers it clearly to be bipolar disorder, the most intuitive approach would be long-term treatment with mood stabilizers. We now have a growing amount of data on the longitudinal course of postpartum psychosis. In one meta-analysis, 64% of women who had an episode of postpartum psychosis developed episodes of recurrent psychiatric disorder mostly consistent with bipolar illness. However, 36% of women appear to have more circumscribed illness without recurrence. In those women with recurrent disease, the presumption was those patients who had bipolar disorder and their presentation postpartum was simply their index episode of bipolar illness. However, there were other women who looked as if they had developed subsequent illness over the 11-26 years of follow-up, and those women did not receive long-term treatment.
A more recent prospective study of 106 women with postpartum psychosis who had their medication tapered and discontinued showed that 32% of women went on to have recurrent disease with a median time to illness of 20.3 months, and those patients presented primarily with illness that looked like bipolar disorder.
These accumulating data support the impression we’ve had for years that there’s a very strong relationship between bipolar disorder and postpartum psychiatric illness. Regardless of what side of the debate you fall on, the acute treatment is really the same. The real question for the clinician is what to do over the long term. Frequently, patients feel very strongly about a taper and discontinuation of medicine, and even the data show between 30% and 45% of women seem to have relatively circumscribed disease. There may be an issue in terms of prophylaxis if a patient gets pregnant and delivers another child, but that’s a separate issue. The issue is really whether there is a way to “thread the clinical needle” and meet patients where they are who do not want to continue long-term treatment.
I think we are at a point where we could argue the clinical treatment algorithm for patients who present with a new-onset manic-like psychosis postpartum is clear: initial treatment to stabilize, and then treatment with mood stabilizers for at least 12 months to follow is indicated. However, it may also be reasonable to taper treatment at 12-18 months, particularly for patients who have discussed this option with their clinician and who have been totally well for a year. (Women with previously documented bipolar disorder who have episodes of postpartum psychosis should obviously be treated with longer-term treatment aimed at maintenance of euthymia, as discontinuation of mood stabilizer is well known to be associated with risk for relapse.)
It should be noted that the longitudinal course and the treatment implications for women with postpartum psychosis are not etched in stone absent a clear evidence base driving care guidelines. Treatment must still be individualized. Women with underlying mood diatheses will typically declare themselves over time, and others may do well if they discontinue treatment, particularly if they are followed closely and instructed to present to a clinician at the earliest symptoms of mood dysregulation. The good news is we’ve seen an evolution of both interest and expertise in acute management of postpartum psychosis and a richer appreciation of the potential heterogeneity of this sample of women. There may be some variability in terms of long-term course requiring personalized treatment and obviously close follow-up of these women.

As I speak with women across the country with histories of postpartum psychosis, I’m often told of the difficult exchanges that women and their partners have at EDs in various clinical settings where diagnosis was delayed, or treatment was incomplete because of staff without expertise in postpartum psychosis management.
Another dilemma that patients and clinicians face after acute treatment is treatment duration, which is derived from how we conceptualize the illness. Even for experts in the area, there is not a consensus on whether postpartum psychosis should be considered as bipolar disorder or whether it is a circumscribed diagnostic entity. This issue has been hotly debated for many years and is one of the reasons why the illness is not included in the DSM classification system.
At Massachusetts General Hospital, we are systematically studying a large cohort of women with histories of postpartum psychosis as part of the MGH Postpartum Psychosis Project to better understand the phenomenology of postpartum psychosis, and also to understand the possible genomic underpinning of the illness. Most recently, we are conducting a neuroimaging study of women with histories of postpartum psychosis, compared with women in a healthy control group. We hope the results of this novel investigation will help to answer whether there is a neural signature identifiable with neuroimaging techniques such as functional MRI, if those findings are similar to other findings of neural circuitry we see in other forms of psychotic illness, or if the illness has a more distinct neural signature.
A question patients and colleagues often ask is what is the long-term nature of postpartum psychosis. If one considers it clearly to be bipolar disorder, the most intuitive approach would be long-term treatment with mood stabilizers. We now have a growing amount of data on the longitudinal course of postpartum psychosis. In one meta-analysis, 64% of women who had an episode of postpartum psychosis developed episodes of recurrent psychiatric disorder mostly consistent with bipolar illness. However, 36% of women appear to have more circumscribed illness without recurrence. In those women with recurrent disease, the presumption was those patients who had bipolar disorder and their presentation postpartum was simply their index episode of bipolar illness. However, there were other women who looked as if they had developed subsequent illness over the 11-26 years of follow-up, and those women did not receive long-term treatment.
A more recent prospective study of 106 women with postpartum psychosis who had their medication tapered and discontinued showed that 32% of women went on to have recurrent disease with a median time to illness of 20.3 months, and those patients presented primarily with illness that looked like bipolar disorder.
These accumulating data support the impression we’ve had for years that there’s a very strong relationship between bipolar disorder and postpartum psychiatric illness. Regardless of what side of the debate you fall on, the acute treatment is really the same. The real question for the clinician is what to do over the long term. Frequently, patients feel very strongly about a taper and discontinuation of medicine, and even the data show between 30% and 45% of women seem to have relatively circumscribed disease. There may be an issue in terms of prophylaxis if a patient gets pregnant and delivers another child, but that’s a separate issue. The issue is really whether there is a way to “thread the clinical needle” and meet patients where they are who do not want to continue long-term treatment.
I think we are at a point where we could argue the clinical treatment algorithm for patients who present with a new-onset manic-like psychosis postpartum is clear: initial treatment to stabilize, and then treatment with mood stabilizers for at least 12 months to follow is indicated. However, it may also be reasonable to taper treatment at 12-18 months, particularly for patients who have discussed this option with their clinician and who have been totally well for a year. (Women with previously documented bipolar disorder who have episodes of postpartum psychosis should obviously be treated with longer-term treatment aimed at maintenance of euthymia, as discontinuation of mood stabilizer is well known to be associated with risk for relapse.)
It should be noted that the longitudinal course and the treatment implications for women with postpartum psychosis are not etched in stone absent a clear evidence base driving care guidelines. Treatment must still be individualized. Women with underlying mood diatheses will typically declare themselves over time, and others may do well if they discontinue treatment, particularly if they are followed closely and instructed to present to a clinician at the earliest symptoms of mood dysregulation. The good news is we’ve seen an evolution of both interest and expertise in acute management of postpartum psychosis and a richer appreciation of the potential heterogeneity of this sample of women. There may be some variability in terms of long-term course requiring personalized treatment and obviously close follow-up of these women.

Managing maternal and infant mental health
An overwhelmed mother presents to your office with her 2-month-old son for his check-up. She seems distant and dysphoric, often shrugging her shoulders with an empty stare when asked about her son’s development. Her baby cries loudly in her arms and you can see that she is uncomfortable soothing him as she frantically rocks him back and forth. He appears to have gained little weight since the last appointment occurring 6 days post partum and his mother describes him as “difficult and fussy all the time.” The father was unable to attend the appointment due to work obligations and often leaves the baby alone with the mother for 10 hours per day. As you examine her son, you counsel the mother on how to care for her baby while also caring for herself. The mother immediately begins to sob into her hands and states: “I can’t do this anymore. I am not meant to be a mother.”
Major depressive disorder with peripartum onset – also known as postpartum depression – is a major public health concern that affects approximately 20% of women in industrial societies like the United States. It is among the most prevalent psychiatric disorders in the world and remains largely underdiagnosed because of lack of access to care, symptom underreporting secondary to stigma, and lack of education regarding illness.1 Adequate treatment of perinatal depression is of paramount importance, as this condition can have significant negative consequences for both mother and child.
Infants raised by depressed mothers show early disruptions in social and emotional development, including diminished security of attachment with their mothers and reduced ability to self-regulate.2 Later in development, the offspring of depressed mothers are at greater risk for psychopathology – most notably anxiety and depression as well as impaired social behavior. 3,4 Rates of depression in school-aged and adolescent children of depressed mothers have been reported to be between 20% and 41%.4 Not only are rates of depression higher, but depression in children of depressed parents, relative to depression in same-age children of nondepressed parents, has an earlier age of onset, longer duration, and is associated with greater functional impairment and risk of relapse.5
In addition, evidence shows that infants of depressed mothers show more negative affect and more self-directed regulatory behaviors, while toddlers show more dysregulated aggression and heightened mood lability.6 Given that these infants also already have an increased genetic risk for depression and anxiety, it is essential that mothers are identified and treated early to prevent these early disruptions to the parent-child relationship.
Pediatricians sit at the intersection of motherhood and infant development. This offers a unique opportunity to influence the trajectory of the child through bolstering supports for the mother. Understandably, time is limited during these brief touchpoints occurring over the first postpartum year, although a heartfelt “How are you?” can make all the difference. In asking this simple question in a disarming way, you may prevent multiple adverse childhood experiences for your tiniest patients.
Further, evidence has shown that toxic stress experienced during sensitive periods of brain development in infants and young children can negatively affect brain architecture. Brain pathways that are rarely used are pruned away, whereas pathways that are readily accessed grow stronger. If children are exposed to toxic stress, whether it be from abuse, mental illness of a caregiver such as severe maternal depression, witnessed domestic violence, or worse, they may begin to experience the world as dangerous and uncertain. This can strengthen connections in parts of the brain associated with fear, arousal, and emotional regulation at the cost of other parts of the brain associated with learning and safety.
Particularly focusing on infancy through preschool, children depend on sensitive, responsive caregivers to learn how to understand emotions and begin to self-soothe. Pediatricians have access to this critical period and can help lead the way toward secure attachment between mother and child. Through taking this dyadic, integrated approach, not only can downstream problems in the child be attenuated or even prevented (that is, disrupted social-emotional development and depression/anxiety), but a mother’s identity can form around her strengths in parenting rather than negative cognitive distortions. Here are some ways to quickly assess a mother for major depressive disorder with peripartum onset so that treatment can be secured, allowing children to develop and learn in a safe, supportive, loving environment:
- Add a standardized instrument to the check-in process during baby’s first year of life. The Edinburgh Postnatal Depression Scale (EPDS) is the most commonly used screening tool, consisting of 10 questions with a score of 10 or greater suggestive of maternal depression. Recently, it was found that the EPDS may be further abbreviated to a three-question version with a sensitivity of 95% and a negative predictive value of 98%.
- Dedicate 5 minutes during each appointment to ask the mother, in earnest, how she is doing and to create space to hear her concerns. This high-yield discussion can be the catalyst the mother needs to identify that something is not right.
- Obtain collateral information from the mother’s partner, if available, in a way that feels collaborative and supportive. You may ask the partner during the appointment if they have any concerns about how both parents are coping with their new parenting roles.
- If the mother has multiple risk factors for major depressive disorder with peripartum onset – past history of depression, family history of perinatal depression, lack of social supports, or past history of major depressive disorder with peripartum onset with an earlier child (elevating their risk to about 50%) – you may dedicate a bit more time to assess the patient and/or provide mental health resources directly upon wrapping up the appointment.
- Finally, you may add an educational blurb about major depressive disorder with peripartum onset in all after-visit summaries for new parents and infants with a list of mental health resources that includes reproductive psychiatrists, therapists, and a link to robust resources like Postpartum Support International.
By taking the extra step to leverage the relationship between mother and infant at this highly vulnerable time, you have the ability to positively affect the trajectory of a family. And, at the end of the day, this dyadic approach to patient care is the secret ingredient to improved outcomes all around.

A 9-year-old girl was evaluated for a week-long history of rash on the feet
A complete body examination failed to reveal any other lesions suggestive of a fungal infection. A blood count and urinalysis were within normal limits. She had no lymphadenopathy or hepatosplenomegaly. She was diagnosed with cutaneous larva migrans (CLM) given the clinical appearance of the lesions and the recent travel history.
CLM is a zoonotic infection caused by several hookworms such as Ancylostoma braziliense, Ancylostoma caninum, and Uncinaria stenocephala, as well as human hookworms such as Ancylostoma duodenale and Necator americanus. The hookworms can be present in contaminated soils and sandy beaches on the coastal regions of South America, the Caribbean, the Southeastern United States, Southeast Asia, and Africa.1-5
It is a common disease in the tourist population visiting tropical countries because of exposure to the hookworms in the soil without use of proper foot protection.
The clinical features are of an erythematous linear serpiginous plaque that is pruritic and can progress from millimeters to centimeters in size within a few days to weeks. Vesicles and multiple tracks can also be seen. The most common locations are the feet, buttocks, and thighs.
The larvae in the soil come from eggs excreted in the feces of infected cats and dogs. The infection is caused by direct contact of the larvae with the stratum corneum of the skin creating a burrow and an inflammatory response that will cause erythema, edema, track formation, and pruritus.
Diagnosis is made clinically. Rarely, a skin biopsy is warranted. The differential diagnosis includes tinea pedis, granuloma annulare, larva currens, contact dermatitis, and herpes zoster.
Tinea pedis is a fungal infection of the skin of the feet, commonly localized on the web spaces. The risk factors are a hot and humid environment, prolonged wear of occlusive footwear, excess sweating, and prolonged exposure to water.6 Diagnosis is confirmed by microscopic evaluation of skin scrapings with potassium hydroxide or a fungal culture. The infection is treated with topical antifungal creams and, in severe cases, systemic antifungals. Granuloma annulare is a benign chronic skin condition that presents with annular-shaped lesions. Its etiology is unknown. The lesions may be asymptomatic or mildly pruritic. Localized granuloma annulare typically presents as reddish-brown papules or plaques on the fingers, hands, elbows, dorsal feet, or ankles. The feature distinguishing granuloma annulare from other annular lesions is its absence of scale.
Allergic contact dermatitis is caused by skin exposure to an allergen and a secondary inflammatory response to this material on the skin causing inflammation, vesiculation, and pruritus. Lesions are treated with topical corticosteroids and avoidance of the allergen.
Herpes zoster is caused by a viral infection of the latent varicella-zoster virus. Its reactivation causes the presence of vesicles with an erythematous base that have a dermatomal distribution. The lesions are usually tender. Treatment is recommended to be started within 72 hours of the eruption with antivirals such as acyclovir or valacyclovir.
Cutaneous larva currens is caused by the cutaneous infection with Strongyloides stercoralis. In comparison with CLM, the lesions progress faster, at up to a centimeter within hours.
CLM is usually self-limited. If the patient has multiple lesions or more severe disease, oral albendazole or ivermectin can be prescribed. Other treatments, though not preferred, include freezing and topical thiabendazole solutions.
As our patient had several lesions, oral ivermectin was chosen as treatment and the lesions cleared within a week. Also, she was recommended to always wear shoes when walking on the beach.

The hookworms can be present in contaminated soils and sandy beaches on the coastal regions of South America, the Caribbean, the Southeastern United States, Southeast Asia, and Africa.1-5
It is a common disease in the tourist population visiting tropical countries because of exposure to the hookworms in the soil without use of proper foot protection.
The clinical features are of an erythematous linear serpiginous plaque that is pruritic and can progress from millimeters to centimeters in size within a few days to weeks. Vesicles and multiple tracks can also be seen. The most common locations are the feet, buttocks, and thighs.
The larvae in the soil come from eggs excreted in the feces of infected cats and dogs. The infection is caused by direct contact of the larvae with the stratum corneum of the skin creating a burrow and an inflammatory response that will cause erythema, edema, track formation, and pruritus.
Diagnosis is made clinically. Rarely, a skin biopsy is warranted. The differential diagnosis includes tinea pedis, granuloma annulare, larva currens, contact dermatitis, and herpes zoster.
Tinea pedis is a fungal infection of the skin of the feet, commonly localized on the web spaces. The risk factors are a hot and humid environment, prolonged wear of occlusive footwear, excess sweating, and prolonged exposure to water.6 Diagnosis is confirmed by microscopic evaluation of skin scrapings with potassium hydroxide or a fungal culture. The infection is treated with topical antifungal creams and, in severe cases, systemic antifungals. Granuloma annulare is a benign chronic skin condition that presents with annular-shaped lesions. Its etiology is unknown. The lesions may be asymptomatic or mildly pruritic. Localized granuloma annulare typically presents as reddish-brown papules or plaques on the fingers, hands, elbows, dorsal feet, or ankles. The feature distinguishing granuloma annulare from other annular lesions is its absence of scale.
Allergic contact dermatitis is caused by skin exposure to an allergen and a secondary inflammatory response to this material on the skin causing inflammation, vesiculation, and pruritus. Lesions are treated with topical corticosteroids and avoidance of the allergen.
Herpes zoster is caused by a viral infection of the latent varicella-zoster virus. Its reactivation causes the presence of vesicles with an erythematous base that have a dermatomal distribution. The lesions are usually tender. Treatment is recommended to be started within 72 hours of the eruption with antivirals such as acyclovir or valacyclovir.
Cutaneous larva currens is caused by the cutaneous infection with Strongyloides stercoralis. In comparison with CLM, the lesions progress faster, at up to a centimeter within hours.
CLM is usually self-limited. If the patient has multiple lesions or more severe disease, oral albendazole or ivermectin can be prescribed. Other treatments, though not preferred, include freezing and topical thiabendazole solutions.
As our patient had several lesions, oral ivermectin was chosen as treatment and the lesions cleared within a week. Also, she was recommended to always wear shoes when walking on the beach.

Her mother reported recent travel to a beachside city in Colombia. A review of systems was negative. She was not taking any other medications or vitamin supplements. There were no pets at home and no other affected family members. Physical exam was notable for an erythematous curvilinear plaque on the feet and a small vesicle.
Polio: The unwanted sequel
Summer, since 1975, is traditionally a time for the BIG blockbusters to hit theaters. Some are new, others are sequels in successful franchises. Some anticipated, some not as much.
And, in summer 2022, we have the least-wanted sequel in modern history – Polio II: The Return.
Of course, this sequel isn’t in the theaters (unless the concessions staff isn’t washing their hands), definitely isn’t funny, and could potentially cost a lot more money than the latest Marvel Cinematic Universe flick.
Personally and professionally, I’m in the middle generation on the disease. I’m young enough that I never had to worry about catching it or having afflicted classmates. But, as a doctor, I’m old enough to still see the consequences. Like most neurologists, I have a handful of patients who had childhood polio, and still deal with the chronic weakness (and consequent pain and orthopedic issues it brings). Signing off on braces and other mobility aids for them is still commonplace.
One of my attendings in residency was the renowned Parkinson’s disease expert Abraham Lieberman. On rounds it was impossible not to notice his marked limp, a consequence of childhood polio, and he’d tell us what it was like, being a 6-year-old boy and dealing with the disease. You learn as much from hearing firsthand experiences as you do from textbooks.
And now the virus is showing up again. A few victims, a lot of virions circulating in waste water, but it shouldn’t be there at all.
We aren’t in the era when schoolchildren died or were crippled by it. Elementary school kids today don’t see classmates catch polio and never return to school, or see their grieving parents.
To take 1 year: More than 3,000 American children died of polio in 1952, and more than 21,000 were left with lifelong paralysis – many of them still among us.
When you think of an iron lung, you think of polio.
Those were the casualties in a war to save future generations from this, along with smallpox and other horrors.
But today, that war is mostly forgotten. And now scientific evidence is drowned out by whatever’s on Facebook and the hard-earned miracle of vaccination is ignored in favor of a nonmedical “social influencer” on YouTube.
So The majority of the population likely has nothing to worry about. But there may be segments that are hit hard, and when they are they will never accept the obvious reasons why. It will be part of a cover-up, or a conspiracy, or whatever the guy on Parler told them it was.
As doctors, we’re in the middle. We have to give patients the best recommendations we can, based on learning, evidence, and experience, but at the same time have to recognize their autonomy. I’m not following someone around to make sure they get vaccinated, or take the medication I prescribed.
But we’re also the ones who can be held legally responsible for bad outcomes, regardless of the actual facts of the matter. On the flip side, you don’t hear about someone suing a Facebook “influencer” for doling out inaccurate, potentially fatal, medical advice.
So cracks appear in herd immunity, and leaks will happen.
A few generations of neurologists, including mine, have completed training without considering polio in a differential diagnosis. It would, of course, get bandied about in grand rounds or at the conference table, but none of us really took it seriously. To us residents it was more of historical note. “Gone with the Wind” and the “Wizard of Oz” both came out in 1939, and while we all knew of them, none of us were going to be watching them at the theaters.
Unlike them, though, polio is trying make it back to prime time. It’s a sequel nobody wanted.
But here it is.
