Clinical Trial Summary

In this study, the investigators will be examining the effects of the deep repetitive transcranial magnetic stimulation (rTMS) using the H1 coil in patients over the age of 60 diagnosed with mild to early-moderate Alzheimer's disease (AD) or mild cognitive impairment (MCI) and comorbid Major Depressive Disorder (MDD) who have been unable to tolerate or failed to respond to antidepressant medications. The coil was designed to stimulate deeper regions of the left dorsolateral prefrontal cortex (DLPFC). Based on prior research, the investigators propose that active stimulation with the H1 coil for 4 weeks may result in significant remission rates and will be tolerable and safe.


Clinical Trial Description

This study is an open-label trial to evaluate the safety and efficacy of H1-coil dTMS in treating depression in MCI and mild AD patients over 60 years of age who have not tolerated or failed to respond to antidepressant medications. 28 patients will be assigned to receive 4 consecutive weeks of daily active dTMS treatment. The long-term effects of treatment on emotional cognitive measures will be assessed at a 4-week follow-up visit (8 weeks from baseline). Symptom change and remission criteria will be assessed using the Montogmery-Asberg Depression Rating Scale (MADRS). Cognition will be assessed using a validated neuropsychological battery. We will also offer patients to receive 4 weeks of treatment using theta-burst TMS, which is a milder version of TMS. ;
