rTMS to Improve Cognition in Parkinson's
Sponsored by VA Office of Research and Development
About this study
The purpose of this study is to examine safety, feasibility, and the behavioral and brain effects of a non-invasive treatment, repetitive transcranial magnetic stimulation (rTMS), for Veterans with Parkinson's disease or atypical parkinsonism and mild impairments in their thinking. The hypothesis is that rTMS can improve thinking for people with Parkinson's disease or atypical parkinsonism who are experiencing mild problems with their thinking ability.
Repetitive transcranial magnetic stimulation (rTMS) shows promise as an effective cognitive neurorehabilitation treatment. To date, no rTMS studies have assessed the effect of rTMS on cognitive function in PD-MCI. Nor has there been PD neurophysiological studies using rTMS to examine neural plasticity in cognitive neural networks. This study seeks to fill this gap by conducting a small scaled pilot randomized controlled trial (RCT) designed to assess the safety and therapeutic effects of rTMS on cognitive outcomes as well as on brain connectivity in Veterans with PD-MCI. PD-MCI participants will be randomized to either active rTMS or sham rTMS. Participants will complete a standardized neurocognitive battery assessment at baseline, endpoint and at a one month follow-up. The primary outcome…
