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: In Drosophila melanogaster, caffeine consumed at night impaired inhibitory control in an airflow task, especially in females. The effect was not explained by simple hyperactivity or sleep deprivation, and the study points to dopamine signaling in mushroom-body circuits as part of the mechanism. Key Findings Nighttime caffeine impaired stopping behavior: flies kept moving under …
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 Nature Communications found that in mice, stress from inflammation, forced cell division, cancer-like pressure, and aging activated MLKL in blood-forming stem cells without causing widespread cell death. Instead, active MLKL built up in mitochondria, damaged the cells’ energy machinery, and made the surviving stem cells age faster. Key Findings Several …
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 MRI study in Brain Imaging and Behavior of 136 healthy young adults found no robust whole-brain gray matter, white matter, cortical thickness, or brain-age differences between early and late chronotypes. Key Findings 136 young adults: The study compared 68 early chronotypes with 68 late chronotypes. No robust whole-brain VBM differences: Voxel-based gray …
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 …
