Is this trial a fit for you?

Likely a good fit

Ideal candidates are older adults over 60 with mild to early-moderate Alzheimer's disease or mild cognitive impairment and comorbid Major Depressive Disorder who have not responded to or tolerated antidepressant medications.

Probably not a fit

Patients with metal implants in their head or a history of increased intracranial pressure may not benefit from this study.

What this trial studies

This study evaluates the effects of deep repetitive transcranial magnetic stimulation (rTMS) using the H1 coil on older adults over 60 diagnosed with mild to early-moderate Alzheimer's disease or mild cognitive impairment, who also suffer from Major Depressive Disorder. Participants will receive 4 weeks of daily active dTMS treatment, with assessments of depression and cognitive function conducted before and after the treatment period. The study aims to determine the safety, efficacy, and long-term effects of this intervention on both emotional and cognitive measures.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life for older adults suffering from both depression and cognitive impairment.

How similar studies have gone: Previous studies have shown promising results with similar approaches using TMS for depression, indicating potential for success in this novel application.
