Brain zapping plus brain games shows promise for Alzheimer's
NCT ID NCT04599764
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a gentle brain stimulation technique (HD-tDCS) combined with computer-based memory exercises in 60 people with early Alzheimer's. The goal was to see if this combination could improve thinking and memory more than either treatment alone. Researchers also used brain scans to look for changes in brain networks linked to any benefits.
