Exploring how brain stimulation affects memory in Alzheimer's disease models

Official title: Imaging the effects of transcranial alternatingcurrent stimulation in an experimental model of Alzheimer's Disease

Funded at Sunnybrook Research Institute · NIH-11040293 · Data updated 2026-11-12

This study is looking at how a gentle brain stimulation technique called tACS might help improve memory and brain activity in people with Alzheimer's disease, and it's designed to be safe and comfortable for long-term use.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals with early-stage Alzheimer's disease or those at risk of developing it.

Less likely to help

Patients with advanced Alzheimer's disease or those with other forms of dementia may not benefit from this research.

What this research studies

This research investigates the effects of transcranial alternating current stimulation (tACS) on brain activity and memory in a model of Alzheimer's disease. By using advanced imaging techniques, the study aims to understand how different frequencies of tACS can influence neuronal oscillations and neurotransmission, which are critical for working memory. The approach is non-invasive and designed to be well-tolerated, making it suitable for long-term application in conditions like Alzheimer's. The goal is to identify biomarkers that can predict how well individuals respond to this type of brain stimulation.

Why it matters

Potential benefit: If successful, this research could lead to new non-invasive treatments that improve memory function in patients with Alzheimer's disease.

How similar studies have gone: Previous studies have shown promising results with tACS in improving cognitive functions in both healthy elderly individuals and Alzheimer's patients, indicating a potential for success in this approach.
