Could zapping the brain help people with a rare form of Alzheimer's see better?
NCT ID NCT07191327
First seen Jun 25, 2026 · Last updated Jul 01, 2026 · Updated 3 times
Summary
This study tests whether a non-invasive brain stimulation technique called HD-tDCS can improve visual and thinking abilities in people with posterior cortical atrophy (PCA), a rare condition often linked to Alzheimer's. Fifty participants will receive either real or sham stimulation over 4 days, with an optional long-term phase. The goal is to see if personalized targeting of brain networks can ease symptoms.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
high-definition transcranial direct current stimulation (HD-tDCS)
What this could lead to
If it works, this could point toward a non-drug way to ease visual and cognitive symptoms in posterior cortical atrophy.
What could go wrong
This is an early, small trial (50 people) testing only short-term effects. The sham group and optional open-label phase mean results may be uncertain.
