Can zapping the brain at home boost memory in Alzheimer's?
NCT ID NCT07839650
First seen Sep 24, 2026 · Last updated Sep 25, 2026 · Updated 1 time
Summary
Researchers are testing whether a home-based brain stimulation technique called transcranial alternating current stimulation (tACS) can improve thinking and memory when combined with computerized cognitive training. The trial enrolls 30 people with mild Alzheimer's disease, who are randomly assigned to receive either real or sham stimulation over eight weeks. Participants complete 40 stimulation sessions and cognitive training exercises, with assessments at the start, after treatment, and at follow-up visits. The study also looks at biological markers and brain activity to understand how the intervention might work.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- transcranial alternating current stimulation (tACS) combined with computerized cognitive training
- What this could lead to
- If it works, this could offer a home-based way to support memory and thinking in people with mild Alzheimer's disease.
- What could go wrong
- This is a small, early-stage trial of 30 people, so any benefits may not hold up in larger studies. The stimulation may not meaningfully change symptoms, and participants must follow a demanding schedule of sessions.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: Patients: * Male or female participants aged ≥18 years at the time of signing the informed consent form; * Clinical diagnosis of mild Alzheimer's disease (AD) according to current clinical criteria; * Availability of a caregiver who can assist the participant and who has successfully completed the required training for the use of the device at home. Caregivers: * Male or female caregivers aged ≥18 years; * Compliance with participation in the in-hospital training; * Mini-Mental State Examination (MMSE) score \>27/30. Exclusion Criteria: * Age below that specified in the inclusion criteria; * Inability to understand; * Contraindications to tACS and TMS (e.g., presence of a cardiac pacemaker or metallic implants incompatible with electrical or magnetic fields, history of epilepsy, or current pregnancy, as assessed using the safety questionnaire).
