Zap your brain at home to fight dementia?
NCT ID NCT06821568
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether 6 months of daily, home-based transcranial direct current stimulation (tDCS) can improve cognitive and motor function in 128 older adults (ages 65-90) with motoric cognitive risk syndrome, a condition that raises dementia risk. Participants use a headset that delivers either real or sham stimulation to the left prefrontal cortex. The main goal is to see if it helps with walking while doing a mental task, with secondary measures of executive function and gait speed.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
transcranial direct current stimulation (tDCS)
What this could lead to
If it works, this could offer a safe, at-home way to slow cognitive decline and improve mobility in older adults at risk for dementia.
What could go wrong
This is an early-stage study with only 128 participants, so results may not apply to everyone. The stimulation may not produce meaningful benefits, and the sham group helps control for placebo effects.
