Home-based brain stimulation to support thinking and movement in older adults at risk for dementia

Official title: Long-term home-based transcranial electrical stimulation for cognitive and motor function in older adults with an increased risk of dementia: a randomized controlled trial

Funded at Hebrew Rehabilitation Center for Aged · NIH-11386375 · Data updated 2026-11-12

This study tests whether delivering gentle electrical stimulation at home can help older adults with motor and thinking difficulties reduce their risk of progressing toward dementia.

Who could benefit from this research

Could help

Older adults with motoric cognitive risk and an increased risk of Alzheimer’s disease or related dementias who can perform dual-task activities

Less likely to help

Some participants may not experience sustained benefits or may not tolerate home stimulation well

What this research studies

Researchers will enroll 128 older adults who have motoric cognitive risk and are at higher risk for Alzheimer’s and related dementias. After a 2-week open-label tDCS period, participants are randomized to receive either weekly home-based brain stimulation for six months or a delayed-start sham, with stimulation targeted to the left dorsolateral prefrontal cortex and guided by a smartphone app for remote testing and monitoring. The trial uses a double-blind design to compare real versus sham stimulation and aims to determine if longer-term home treatment can improve dual-task gait and executive function beyond short-term benefits. Outcomes include measures of gait during cognitive tasks, cognitive performance, and safety in a real-world home setting. If successful, this approach could offer a practical way to delay cognitive decline in at-risk older adults.

Why it matters

Potential benefit: If successful, home-based brain stimulation could slow cognitive decline and improve daily functioning for people at risk of dementia.

How similar studies have gone: Prior short-term home-based tDCS trials showed improvements in dual-tasking and executive function, but longer-term benefits are still being tested
