Exploring how Alzheimer's affects response to brain stimulation therapy

Understanding How Alzheimer's Disease Impacts the Therapeutic Response to Transcranial Direct Current Stimulation

Not applicable Interventional Baycrest · NCT05508841

This study is testing if a stronger type of brain stimulation therapy can help people with Alzheimer's and Frontotemporal dementia improve their thinking skills better than the usual strength.

What this trial studies

This study investigates the effects of transcranial direct current stimulation (tDCS) on individuals with Alzheimer's Disease (AD) and Frontotemporal dementia (FTD). The researchers aim to determine the optimal stimulation parameters, specifically testing a higher intensity of 4.0 mA compared to the conventional 2.0 mA, to enhance therapeutic responses. By assessing cognitive improvements through tDCS combined with cognitive training, the study seeks to identify which patients may benefit most from this intervention. The variability in previous studies' results prompts this investigation to refine treatment approaches for better clinical outcomes.

Who should consider this trial

Good fit: Ideal candidates include individuals with mild to moderate Alzheimer's Disease who can perform specific cognitive tasks.

Not a fit: Patients with a history of stroke, traumatic brain injury, or significant heart disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective therapeutic options for patients with Alzheimer's Disease and Frontotemporal dementia.

How similar studies have performed: While some studies have shown promise with tDCS in cognitive enhancement, this specific approach of varying stimulation intensity is relatively novel.
