TL;DR: A 2026 Molecular Psychiatry study tested Regional Vulnerability Index for Alzheimer’s disease (RVI-AD), a structural-MRI score of how closely a person’s brain pattern resembles amyloid-positive Alzheimer’s disease, and found that higher RVI-AD predicted…

TL;DR: A 2026 Reviews in the Neurosciences review argues that glycolysis, the cell pathway that turns glucose into usable energy and lactate, is a disease-shaping process across Alzheimer’s disease, Parkinson’s disease, ALS, Huntington’s disease, Wilson diseas…

TL;DR: A 2026 narrative review in the Japanese Journal of Radiology reported that Alzheimer’s brain positron emission tomography (PET) imaging has shifted from supportive diagnosis toward treatment selection because amyloid PET is now central to confirming eli…

TL;DR: A 2026 preprint in medRxiv found that under-mattress sleep sensors associated lower nighttime respiratory rate and more unstable nighttime movement with higher odds of next-day agitation in dementia, while the same features did not predict how severe ag…

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 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 medRxiv preprint used total-body tau PET in Alzheimer’s disease and found stronger brain-organ network synchrony, a pattern that tracked cognitive impairment through cortical tau burden and MRI markers of glymphatic dysfunction. Key Findings Smal…

TL;DR: A 2026 Nature Communications paper found that late-stage amyloid beta plaques in APP23 mice recruited CD8 T cells with a type I interferon program, linking Alzheimer-like amyloid pathology to a more adaptive immune response around plaques. Key Findings…
