Ketamine for the Treatment of Depression in Parkinson's Disease

Abstract

The main purpose of this study is to examine the efficacy and safety of a repeated dosing ketamine infusion paradigm compared to placebo in individuals with PD. A subset of participants in each arm will undergo baseline and post-treatment PET and fMRI scans, to examine whether changes in synaptic density and reorganization of functional networks underlie ketamine's putative antidepressant effects in PD.
