TL;DR: A 2026 case-control study in Psychological Medicine linked major depressive disorder to faster blood-based transcriptomic aging and found that right-insula brain changes partly explained the depression association. Key Findings Transcriptomic aging was…

TL;DR: A 2026 preprint in medRxiv found that poor sleep tracked faster biological aging across more than 64,000 adults, but twin and genetic analyses left the causal claim mixed rather than settled. Key Findings 64,000+ adults: Researchers tested sleep and agi…

TL;DR: A 2026 study in Epigenetics found that DNA methylation clocks, which estimate biological aging from chemical marks on DNA, gave substantially older age estimates in saliva than in two blood-derived samples from 91 early-to-mid-adult participants. Key Fi…

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 mul…

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…

Adversity accelerates biological aging through health-compromising behaviors like smoking and possibly social disconnection, and future research needs to focus on causal methodologies to better understand these processes and develop effective interventions. Hi…
