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 medRxiv preprint applied ChatGPT-4o-assisted Bayesian-frequentist hybrid inference to Alzheimer’s single-nucleus RNA-seq data and identified gamma-secretase and HP1 transcription pathways that a no-evidence frequentist setting did not recover. Ke…

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 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 study in Glia used human single-nucleus RNA sequencing datasets and mouse validation to identify a shared neurodegeneration-linked microglial transcription program, highlighting SPP1 as a disease-associated microglia marker. Key Findings Five dis…

TL;DR: A 2026 medRxiv preprint linked higher blood inflammatory markers with diffusion MRI signs of altered white-matter microstructure in 457 dementia-free middle-aged and older adults, especially for a combined cytokine score and orientation dispersion index…

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 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…
