Everyday Chemicals Linked to Lasting Memory Damage, New Study Finds
New research published this week and covered by PsyPost (April 7, 2026) found that maternal exposure to short-chain PFAS - a class of chemicals used in non-stick cookware, food packaging, water-resistant clothing, and countless other consumer products - causes persistent memory problems in adult rats whose mothers were exposed during pregnancy. The damage endured well into adulthood, long after the exposure itself had ended.
PFAS, sometimes called "forever chemicals" because they do not break down in the body or environment, have been detected in the blood of nearly all Americans. Prior research has linked them to hormone disruption, immune suppression, and cancer risk. This latest study adds neurological harm to that list - specifically memory impairment - and raises urgent questions about what long-term, low-dose PFAS exposure means for human cognitive and mental health across generations.
For anyone paying attention to the science of the mind and body, the message is increasingly hard to ignore: the chemical environment we live in is not neutral. It shapes the brain we carry.
ADHD Is More Than the DSM Describes - New Research Identifies 9 Symptom Categories
A new study reported by Psychology Today (April 7, 2026) found that the current diagnostic criteria for ADHD in the DSM - psychiatry's official classification manual - do not fully capture what people with ADHD actually experience. Researchers identified nine distinct symptom categories, several of which do not appear anywhere in the DSM's current framework.
These include categories related to emotional dysregulation, sensory sensitivity, time blindness, rejection sensitivity, and problems with working memory that fall outside the traditional inattention/hyperactivity split. The findings align with years of clinician observations and patient self-reporting that the DSM criteria feel incomplete - and they add scientific weight to growing calls for a broader, more accurate diagnostic picture.
This matters especially for the many people - particularly women and adults - who are diagnosed late or not at all because their experience of ADHD doesn't match the textbook template. Accurate diagnosis is where healing begins.
The Keto Diet Is Not a Psychiatric Treatment, Researchers Warn
Despite a wave of online and media claims that the ketogenic diet is a breakthrough "cure" for mental illness - including bipolar disorder, schizophrenia, and depression - psychiatrists Sara and Jack Gorman published a pointed corrective in Psychology Today on April 7, 2026: the evidence simply does not support this.
While keto has demonstrated efficacy for drug-resistant epilepsy, and some preliminary studies have explored its metabolic effects on mood, there are no large-scale, randomized controlled trials proving psychiatric benefit. The Gormans caution that the enthusiasm is outrunning the data, and that patients may abandon proven treatments in favor of a diet-based intervention that lacks clinical validation.
The piece is a reminder that in an age of wellness marketing, separating signal from noise requires rigor - not just optimism. Healing is real. So is the difference between anecdote and evidence.
The APA Releases Its Roadmap for the Future of Psychiatric Diagnosis
The American Psychiatric Association (APA) released a series of papers this week outlining a proposed roadmap for the future of the Diagnostic and Statistical Manual of Mental Disorders (DSM) - the foundational text that shapes how mental illness is diagnosed and treated across the United States and much of the world.
Authored by the APA's Future DSM Strategic Committee, chaired by University of Pennsylvania psychiatry chair Dr. Maria Oquendo, the papers are published in the American Journal of Psychiatry. They propose a shift toward dimensional, transdiagnostic frameworks that move beyond categorical yes/no diagnoses - recognizing that mental health conditions exist on spectrums, co-occur frequently, and are shaped by biology, environment, culture, and lived experience in ways the current manual does not fully reflect.
The DSM has not undergone a major revision since DSM-5 in 2013. As science advances - from genetics and neuroimaging to AI-assisted pattern recognition - the push to modernize the diagnostic system is gaining real institutional momentum. What the DSM says shapes not just what clinicians look for, but what society understands mental illness to be.
