TL;DR: A 2026 medRxiv preprint found that older adults with Montreal Cognitive Assessment (MoCA)-defined mild cognitive impairment had less coordinated pulse-wave responses during a cognitive challenge than cognitively intact older adults. Key Findings Communi…

TL;DR: A 2026 systematic review and meta-analysis in Psychogeriatrics linked loneliness with Alzheimer’s disease and several forms of suicidal behavior, with especially strong shared correlations for hopelessness, insomnia, entrapment, and stress. Key Findings…

TL;DR: A 2026 preprint on medRxiv used resting-state functional MRI (fMRI), a brain-connectivity scan taken while people are not doing a task, to divide older adults at Alzheimer’s risk into anxiety biotypes that responded differently to frontal-lobe tDCS stim…

TL;DR: A 2026 mouse study in iScience found that blocking Itch, an E3 ubiquitin ligase involved in protein tagging, improved several memory-test readouts in an Alzheimer’s disease mouse model and reduced neuronal apoptosis, including when researchers used the…

TL;DR: A 2026 preprint in medRxiv used natural language processing (NLP) on Scottish CT and MRI reports to subtype stroke at scale, linking lobar intracerebral hemorrhage to higher later dementia risk and cortical ischemic stroke to higher early myocardial inf…

TL;DR: A 2026 population-based matched cohort study in British Journal of Psychiatry found that risperidone use was associated with increased stroke risk, adjusted hazard ratio 1.28, while absolute stroke incidence was especially high in people with prior stro…

TL;DR: A 2026 medRxiv preprint found that specific AD8 dementia-screening items, especially judgment, repetition, finances, tool use, and daily memory problems, tracked functional and psychosocial vulnerability in 144 Chinese-speaking older adults. Key Finding…

TL;DR: A 2026 modeling study in Journal of Mathematical Biology found that delayed unfolded protein response (UPR), a cellular stress program that slows protein production, could make toxic prion protein either die out, persist, or oscillate as it spreads thro…
