Home-Based Gamma tACS Improves Cognitive Function and Daily Living in Alzheimer Disease: Results from a Randomized Clinical Trial

A randomized clinical trial demonstrates that home-based gamma transcranial alternating current stimulation (tACS) over the precuneus safely improves cognitive outcomes and activities of daily living in patients with prodromal and mild Alzheimer disease, supported by neurophysiological evidence of brain engagement.

White Matter Microstructure and Cognitive Decline in Aging and Alzheimer Disease: A Comprehensive Review of Recent Advances

This review synthesizes recent large-scale multi-cohort studies revealing white matter microstructural abnormalities—especially free water increases—in limbic tracts as critical markers of cognitive decline in aging and Alzheimer's disease, emphasizing integrated biomarker approaches.

Lower Posttreatment Amyloid Predicts Slower Clinical Decline and Reduced Tau/Glial Biomarkers After Donanemab: Secondary Analysis of TRAILBLAZER‑ALZ 2

A secondary analysis of TRAILBLAZER‑ALZ 2 found that lower posttreatment amyloid plaque levels after donanemab correlate strongly with less clinical decline and reductions in plasma p‑tau217, p‑tau181, and GFAP over 76 weeks, supporting plaque removal as a likely mechanism of benefit.
