TL;DR: A 2026 study in JAMA Network Open found that a therapy built to restore reward and positive emotion outperformed a matched negative-affect therapy for adults with depression, anxiety, and severely low positive affect. Key Findings PAT beat the matched therapy: Positive Affect Treatment improved the composite clinical-status outcome more than Negative Affect Treatment (d …
TL;DR: A 2026 study in The British Journal of Psychiatry found that serious mental illness labels shifted often in real-world psychiatric records: 64% of patients with schizophrenia, bipolar disorder, or severe major depression received multiple diagnoses over time. Key Findings Diagnosis switching was the norm: The cohort covered records from 2005 to 2022 at a …
TL;DR: A 2026 study in Translational Psychiatry found that three different plasma p-tau217 assays separated Alzheimer’s dementia from controls and frontotemporal degeneration with excellent accuracy, shifting the test from whether the marker works to which platform clinics can deploy. Key Findings Three p-tau217 assays all performed strongly: The cohort included 39 cognitively unimpaired controls, 28 …
TL;DR: A 2025 study in Communications Biology found that a week-long mind-body retreat shifted brain-network, plasma-protein, metabolomic, and cell-growth measures, but the uncontrolled design keeps the result exploratory. Key Findings Healthy retreat attendees were measured: The 20 participants were sampled from 561 retreat attendees and measured before and after the intervention. 33 hours meditation: The …
TL;DR: A 2026 study in Psychopharmacology found that after 14 days of unpredictable chronic stress, a single 1-hour ayahuasca exposure restored sociability, reduced anxiety-like behavior, normalized cortisol, and rescued whole-brain BDNF in adult zebrafish within 24 hours. Key Findings 396 fish across 6 groups: Adult zebrafish were split into stressed and non-stressed groups, then exposed …
TL;DR: A 2026 preprint UK Biobank neuroimaging study in medRxiv found that the comorbidity group showed widespread lower cortical volume, subcortical differences, and white matter microstructure alterations, while several alterations appeared unique to the chronic pain-depression comorbidity group. Key Findings Evidence map: a cross-sectional neuroimaging analysis comparing comorbid chronic pain and depression with pain-only, depression-only, …
TL;DR: A 2026 preprint birth-cohort study in medRxiv found that 91.1% of children had experienced violence by age 8, while age-8 violence exposure was associated with higher internalizing, externalizing, total problem scores, and disorder odds. Key Findings Evidence map: a South African birth-cohort analysis using violence reports and child mental health assessment. Study group: 974 …
TL;DR: A 2026 network analysis study in European Archives of Psychiatry and Clinical Neuroscience found that insomnia was present in 18.3% and childhood trauma in 49.5% of patients, while daytime dysfunction and sleep-related distress were central nodes, while mood symptoms and difficulty falling asleep bridged domains. Key Findings Evidence map: a network analysis connecting childhood …
TL;DR: A 2026 BMC Medicine study of UK Biobank adults linked adversity in both childhood and adulthood to higher frailty, older metabolomic age profiles, lower grip strength, and some telomere differences, with the clearest associations in people reporting multiple adverse events. Key Findings Large cohort: The study analyzed up to 153,557 middle-aged and older UK …
TL;DR: A 2026 cohort study in BJPsych Open found that childhood attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) difficulties predicted poorer young-adult outcomes, but rare copy number variants (CNVs), which are deleted or duplicated DNA segments, did not clearly sharpen that prognosis. Key Findings 8,414 young people had CNV data: Researchers analyzed genetic and …
