PTSD Linked to Accelerated Brain Aging

A new study using advanced deep-learning brain age estimation shows that World Trade Center responders with PTSD exhibit signs of accelerated brain aging. Using BrainAgeNeXt, a model trained on more than 11,000 MRI scans, researchers found that responders with PTSD had “older” appearing brains than those without the disorder, especially among individuals with longer exposure at Ground Zero.

Prenatal Acetaminophen Linked to Higher Autism, ADHD Risk

A new study has raised concerns about the safety of acetaminophen use during pregnancy, linking prenatal exposure to higher risks of autism and ADHD. Using the gold-standard Navigation Guide review method, the team analyzed 46 studies with over 100,000 participants, finding that stronger studies more consistently showed a connection.

Brain Circuit Model Reveals How Striatum Shapes Everyday Decisions

Researchers have developed a computational framework that maps how the striosomal compartment of the striatum governs everyday decision-making. By integrating biology, decision theory, and mathematical modeling, the study reveals that different levels of striosomal activity can push individuals toward impulsive, balanced, or overly complex decisions.

Fat Molecule May Control How You Feel Emotion

Scientists have uncovered how the brain’s 5-HT1A serotonin receptor—vital in mood regulation—functions at the molecular level. This receptor, a common target of antidepressants and psychedelics, prefers certain signaling pathways no matter the drug, but drugs can still vary in how strongly they activate them.

Gut Bacteria, Food Insecurity, and Cognitive Risk Intertwined

A new study highlights how food insecurity may intensify the relationship between gut microbiome imbalances and cognitive impairment in adults. Analyzing data from 360 participants, researchers found specific bacterial “cliques” linked to poor cognitive outcomes, especially among those with limited access to nutritious food.

Postpartum Psychosis May Run in Families

Women are over 10 times more likely to develop postpartum psychosis if their sister has experienced the condition, according to a major study of more than 1.6 million women. This rare but severe disorder, marked by hallucinations, paranoia, and disorganized thinking after childbirth, can have life-threatening consequences if not treated.

Dopamine’s Hidden Role in Anxiety Revealed

Dopamine receptors in the ventral hippocampus play a critical role in balancing approach and avoidance behaviors, expanding understanding beyond dopamine’s known functions in reward and motivation. By studying D1 and D2 receptor-expressing neurons in mice, researchers found these receptors govern opposing emotional responses under stress.

How the Brain Judges Social Encounters

Scientists have identified the neural circuitry responsible for assigning emotional value—positive or negative—to social encounters. Two key neuromodulators, serotonin and neurotensin, were found to control opposing emotional responses in a brain region responsible for learning and memory.
