A 2026 Acta Neuropathologica study found that oligomeric tau was linked to early nuclear lamina disruption in Alzheimer’s disease tissue, PS19 tauopathy mice, and human induced pluripotent stem cell (iPSC)-derived neurons.1 The strongest claim is mechanistic: tau oligomers appeared to deform the nuclear envelope and disturb chromatin before overt neurodegeneration, but the work does not …
A 2026 mechanistic Alzheimer’s study found that suppressing NDST3 shifted lysosomal pH in APP695Swe neuronal cells from 5.6 back below 5.0, then reduced amyloid-β, MAPT/tau pathology, neuronal injury, and memory deficits in 3xTg-AD mice.1 Research Highlights Lysosome pH moved back down: APP695Swe-overexpressing HT22 cells had lysosomal pH around 5.6, while NDST3 knockdown re-acidified lysosomes to …
A 2026 ADNI study reported 85.23% accuracy for ANA-GNN, a graph neural network that combined structural MRI regional features with clinical variables to classify cognitively normal controls, mild cognitive impairment, and Alzheimer’s disease.1 The result is useful, but the clinical-feature ablation dropped accuracy to 68.35%, so the model should be read as multimodal decision-support research, …
A 2026 single-cell and spatial-transcriptomics study of 21,156 brain immune cells found that late amyloid disease shifted interferon-driven neuroinflammation from microglia toward plaque-associated CD8 T cells, with T-cell frequency strongly tracking total amyloid deposits (Spearman rho = 0.844, p < 0.0001).1 The result does not turn Alzheimer’s disease into an autoimmune disease, but it makes …
A 2026 iScience study found that 45 days of clomipramine improved spatial, working, and reference memory in female APP/PS1 Alzheimer’s-model mice, apparently by blocking the E3 ubiquitin ligase Itch rather than by clearing amyloid plaques.1 Research Highlights 45-day clomipramine signal: 6-month female APP/PS1 mice received 25 mg/kg clomipramine every other day for 45 days, then …
Statins do not look like a dementia-prevention drug, but they do not look like a dementia hazard either. In 322,358 Kaiser Permanente Northern California patients followed for an average of 11.8 years, dementia diagnoses rose right after statins were started, then flattened: after the first year, the hazard ratio for Alzheimer’s disease and related dementias …
A 2026 Molecular Psychiatry study found that RVI-AD, a structural-MRI score measuring how closely a person’s brain anatomy matches an Alzheimer’s disease pattern, predicted mild-cognitive-impairment conversion to dementia most strongly over the next 3 years: OR 2.16, 95% CI 1.81-2.57, p < 2e-16, AUC 0.70.1 Research Highlights Short-term conversion signal: in 965 ADNI participants with …
