Testing stronger brain stimulation to improve naming ability in Alzheimer's patients

Investigating if a Stronger tDCS Intensity is More Effective for Improving Naming Ability in People Living With Alzheimer's Disease

Not applicable Interventional Baycrest · NCT05509387

This study is testing if stronger brain stimulation can help people with mild to moderate Alzheimer's Disease improve their naming skills better than the usual strength.

What this trial studies

This study investigates the effectiveness of transcranial direct current stimulation (tDCS) at a higher intensity of 4.0 mA compared to the conventional 2.0 mA in improving naming abilities in individuals with mild to moderate Alzheimer's Disease. The goal is to determine if a stronger stimulation can lead to more significant improvements in cognitive function, particularly in naming tasks. Participants will undergo tDCS treatment alongside naming training to assess the impact on their cognitive abilities. The study aims to clarify the optimal parameters for tDCS to enhance its clinical application for Alzheimer's and Frontotemporal dementia.

Who should consider this trial

Good fit: Ideal candidates are individuals with mild to moderate Alzheimer's Disease who have a MoCA score between 18 and 25.

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 approach could lead to more effective non-pharmacological treatments for cognitive impairment in Alzheimer's patients.

How similar studies have performed: Previous studies have shown variable success with tDCS, but this specific approach of increasing stimulation intensity is novel and has not been extensively tested.
