TL;DR: A 2026 randomized trial in The British Journal of Psychiatry found 6 ketamine infusions improved severe treatment-resistant depression, but curated music added no measurable benefit; higher mystical-experience scores still predicted the next session’s depression outcome. Key Findings MADRS fell 11.8 points by week 4: Scores dropped from 31.5 to 19.7 (d = 1.2, p …
DLPFC-sgACC Circuit Signal Predicted rTMS Remission TL;DR: Before starting rTMS, patients who later remitted from depression showed lower alpha-band connectivity flowing from the DLPFC to the subgenual cingulate — pointing toward a measurable EEG marker that could help select candidates before weeks of treatment are spent. Key Findings Remitters had lower pre-treatment DLPFC-to-sgACC alpha connectivity: …
Ketamine Restored Reward Bias Across Species TL;DR: Ketamine restored reward-learning bias in both treatment-resistant depression and chronically stressed rats while leaving basic discrimination unchanged. Key Findings Reward bias increased: Ketamine significantly increased response bias toward the more frequently rewarded stimulus in both species. Healthy-control levels returned: The reward-bias effect reached levels comparable with healthy controls …
Childhood Trauma Made Teen Depression Networks More Random TL;DR: In 343 adolescents with major depression, childhood trauma was linked to less efficient brain-network organization, partial normalization after treatment, and an fMRI-based model that predicted antidepressant response with 82% balanced accuracy. Key Findings 343 depressed adolescents scanned: The study analyzed resting-state functional MRI (fMRI) in adolescents …
Depression Genetics Points to Altered DLPFC Cell Types TL;DR: A Nature Genetics study mapped more than 200,000 cells from the dorsolateral prefrontal cortex and found depression-linked regulatory changes concentrated in deep-layer excitatory neurons and a microglia subtype. Key Findings 84 postmortem DLPFC donors: The analysis compared dorsolateral prefrontal cortex tissue from people with major depression …
Hormone Therapy Linked to 44% Improvement in Menopause Mood Symptoms TL;DR: Menopausal hormone therapy tracked with a 44.59% improvement in mood-symptom scores after about 107 days, across both peri- and postmenopausal women — and the gains were broadly similar regardless of which hormonal regimen was used. Key Findings 44.59% improvement in mood symptoms: After initiating …
Semaglutide Linked to 42% Fewer Psychiatric Hospital Episodes TL;DR: In Swedish registry data covering nearly 100,000 people with depression or anxiety, psychiatric hospital visits and sickness absence were 42% lower during semaglutide treatment periods — with comparable reductions in depression, anxiety, and substance-use outcomes. Key Findings 42% lower psychiatric care during semaglutide periods: Psychiatric hospital …
The Hidden Postpartum Crisis Nobody Screens For: Paternal Depression Peaks at 10-12 Months TL;DR: Fathers experience a protective period early postpartum (depression drops by 26%), but depression and stress surge at months 10-11, creating a 30-36% elevated risk when no one is screening for it. Perinatal psychiatry has a crisis of attention. Mothers are screened …
When Depression Threatens Pregnancy: A 34% Elevated Miscarriage Risk TL;DR: Untreated depression increases miscarriage risk by 34% across nearly 9 million women, but antidepressants reduce that risk to 24%—meaning the medication is safer than the disease during pregnancy. For decades, obstetricians have asked the wrong question about depression in pregnancy. They worried: Is the antidepressant …
How Ketamine Rewires Receptors to Beat Depression TL;DR: Using PET imaging to directly visualize AMPA receptors in the living human brain, researchers discovered that ketamine’s rapid antidepressant effect works by reshuffling these receptors across specific brain regions in patients with treatment-resistant depression — and where they go predicts who will respond to the drug. Nearly …
