rTMS Over the Dorsolateral Prefrontal Cortex for the Treatment of Impulse Control Disorders in Parkinson's Disease

Description

This study's objective is to evaluate the effects of repetitive transcranial magnetic stimulation (rTMS) over the dorsolateral prefrontal cortex (dlPFC) of patients with Parkinson's Disease (PD) who experience impulse control disorders (ICDs) on impulse control symptoms and cognitive behaviors linked to ICDs: reinforcement learning and delay-discounting. This is a randomized sham-controlled cross-over trial. All patients will undergo a session of active rTMS and a session of sham rTMS, with the order of sessions randomized across participants. Following recruitment and eligibility screening, the eligible participants will undergo two sessions of rTMS (active and sham), immediately followed by neurocognitive tasks and questionnaires, no more than 1-2 weeks apart. Each session will have a duration of approximately 1-1.5 hours.
