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…

TL;DR: A 2026 protocol in PLOS One describes a 90-person pilot randomized controlled trial that will test whether virtual reality mindfulness can reduce depression, anxiety, stress, and caregiver burden in family caregivers of people with dementia. Key Finding…

TL;DR: A 2026 mouse study in Proceedings of the National Academy of Sciences found that deleting or inhibiting PTP1B improved memory behavior, reduced amyloid-beta burden, and pushed microglia toward an amyloid-clearing state. Key Findings Memory behavior impr…

TL;DR: A 2025 study in The Journal of Prevention of Alzheimer’s Disease found that stress internalization, not acculturation or activity engagement, predicted memory decline across three waves in 1,528 older Chinese Americans. Key Findings Stress internalizati…

TL;DR: A 2026 preprint longitudinal cohort analysis in medRxiv found that later-born cohorts showed higher memory levels entering old age and slower rates of memory decline, while the projected 20-year cohort advantage at age 80 was large enough in the model t…

TL;DR: A 2026 longitudinal analysis in the Journal of Affective Disorders tracked 635 older adults with new-onset loneliness and found that cognitive decline matched controls before loneliness began, then accelerated after onset, especially when loneliness per…

TL;DR: A 2026 medRxiv preprint applied the AT(N) framework, an Alzheimer’s disease biomarker system for amyloid, tau, and neurodegeneration, to 84 older adults with focal epilepsy and found that only 32.1% had normal blood biomarkers, while early-onset epileps…

TL;DR: A 2026 study in Microbiome found that in older adults at metabolic risk, virgin olive oil was linked to better cognitive preservation and richer gut microbiota, while common refined olive oil pointed the other way. Key Findings Metabolic-risk cohort tra…

TL;DR: A 2026 study in Cell Chemical Biology found that alzheimer’s inflammation may be driven by a specific chemical switch: S-nitrosylation of STING at cysteine 148, which pushed innate immune signaling toward synaptic damage. Key Findings STING carried the…
