TL;DR: A 2026 systematic review in The British Journal of Psychiatry linked schizophrenia to a multisystem advanced-aging phenotype, including older-appearing brain scans, shorter telomeres, inflammation, and higher dementia risk. Key Findings 170 studies incl…

TL;DR: A 2026 meta-analysis in Psychological Medicine found postpartum depression (PPD) brain-activity differences across default-mode, limbic, and sensorimotor regions, with spatial overlap in serotonin, dopamine, and vesicular acetylcholine transporter maps.…

TL;DR: A 2026 medRxiv preprint found that plasma p-tau217 AI models still separated amyloid-positive from amyloid-negative people across ADNI and A4, but calibration drift made the same probabilities less dependable for clinical decisions. Key Findings Calibra…

TL;DR: Across 4,000+ people, the relationship between brain activity and cognitive control flipped direction depending on whether researchers compared people to each other or tracked the same person over time. The finding is called nonergodicity — and it means…

TL;DR: A 2026 review in BMC Psychiatry found 441 primary MRI and electroencephalogram (EEG), a scalp recording of brain electrical activity, mental-health biomarker studies, but most were small, cross-sectional, and concentrated in depression, making routine c…

TL;DR: A 2022 study in Nature Communications used non-contrast 3D T2-FLAIR MRI, a scan that suppresses ordinary cerebrospinal-fluid brightness, to map possible brain-border drainage routes toward cervical lymph nodes, but FLAIR brightness alone does not prove…

TL;DR: A 2025 systematic review in Translational Psychiatry found that substance use disorder was associated with recurring resting-state functional MRI (rs-fMRI), a scan of spontaneous brain-network communication, abnormalities in reward and self-control circ…

TL;DR: A 2026 study in PLOS Medicine found that severe infections stayed linked to later dementia in Finland even after researchers accounted for a broad set of noninfectious comorbid diseases. Key Findings 62,555 dementia cases: The analysis matched Finnish a…

TL;DR: A 2026 medRxiv preprint on schizophrenia reported that illness insight tracked with resting-state functional MRI (fMRI) flexibility, a measure of how dynamically brain regions reconfigure their connectivity, and that these brain-dynamics patterns aligne…

TL;DR: A 2026 systematic review and meta-analysis in Molecular Neurobiology found that plasma phosphorylated tau 217 (p-tau217), a blood marker of Alzheimer-linked tau pathology, identified biomarker-defined Alzheimer’s disease with pooled sensitivity of 85.4%…
