TL;DR: A 2026 study in Biological Psychiatry: Global Open Science linked serious physical injury to recurrent major depression and found that injury-related DNA methylation patterns differed by depression status, with oxytocin, GABA, and synaptic-plasticity pathways standing out. Key Findings Large cohort anchor: researchers analyzed 4,308 Generation Scotland participants with or without a reported fracture from …
TL;DR: A 2026 preprint in medRxiv found that treatment-resistant depression affected 34% of medication-exposed major-depression patients in Pakistan’s DIVERGE study, with social support and CYP2C19 metabolizer status standing out as locally important treatment-response markers. Key Findings 3,677 eligible patients: The treatment-resistance analysis included adults with major depressive disorder who had medication exposure and enough adherence …
TL;DR: A 2026 nationwide claims study in Integrative Medicine Research found that Korean traditional medicine care without recorded acupuncture claims had the lowest modeled costs and the highest 3-year QALYs among four menopausal-disorder treatment strategies, while acupuncture and integrative-care groups appeared to include sicker, higher-utilization patients. Key Findings 32,941 women: The retrospective cohort used Korean …
TL;DR: A 2026 preprint in medRxiv linked recurrent major depression to direction-specific effective-connectivity changes, with strongest patterns in cerebellar-cortical, sensorimotor, cognitive, neurotransmitter, and oligodendrocyte precursor cell maps. Key Findings 1,627-person discovery dataset: REST-meta-MDD resting-state functional MRI (fMRI) and T1 MRI data compared 839 people with major depression and 788 controls. Recurrent depression pattern: First-episode drug-naive …
TL;DR: A 2026 study in BJPsych Open found that closely monitored antidepressant care improved quality of life and reduced societal costs in both PReDicT and usual-care groups, while the PReDicT algorithm added uncertain, country-dependent economic value. Key Findings Multinational trial data anchored the analysis: The economic evaluation followed 913 patients in France, Germany, the Netherlands, …
TL;DR: A 2026 systematic review and meta-analysis in Journal of Sleep Research found that agomelatine modestly improved subjective sleep quality versus placebo, but objective total sleep time did not significantly increase and somnolence reports were more frequent. Key Findings 25 RCTs: The review included 25 double-blind randomized controlled trials with 6,812 randomized participants. Subjective sleep …
TL;DR: A 2026 review in Neuropsychiatric Disease and Treatment argues that miR-425-3p is a candidate depression biomarker because it connects stress biology, MAPK/Wnt signaling, inflammation, and antidepressant response evidence. Key Findings 280 million MDD burden: The review opens from the scale of major depressive disorder, which affects more than 280 million people worldwide. About 20-fold …
TL;DR: A 2026 randomized study in The British Journal of Psychiatry found that the experimental 5-HT4 receptor agonist PF-04995274 did not mimic citalopram’s early emotional-bias effects in unmedicated depression, but it was linked with lower depression ratings and increased medial-frontal brain activation after about 1 week. Key Findings 90 randomized adults: The RESTAND study assigned …
TL;DR: A 2025 study in Psychological Science found that depressive symptoms accelerated about 4 years before death in a multinational twin consortium, suggesting that late-life mood worsening can partly reflect terminal decline rather than chronological age alone. Key Findings 2,411 older-adult records: Researchers analyzed longitudinal depressive-symptom data from the Interplay of Genes and Environments across …
TL;DR: A 2026 systematic review in Molecular Psychiatry found that microglia-related findings across major depression, bipolar disorder, and schizophrenia were better explained by biological subgroups than by one uniform diagnosis-by-diagnosis inflammation pattern. Key Findings Three evidence streams: The review integrated human translocator protein positron emission tomography (TSPO-PET) imaging, cerebrospinal fluid kynurenine-pathway metabolites, and postmortem microglial …
