Dual-Task Improvement in Parkinson's Via rTMS

This study aimed to evaluate the effects of repetitive transcranial magnetic stimulation (rTMS) applied to the left dorsolateral prefrontal cortex on cognitive function and dual-task performance in individuals with Parkinson\'s disease. Participants completed ten rTMS sessions over two weeks or received sham stimulation. Cognitive status was assessed using the Montreal Cognitive Assessment, and mobility was evaluated through single-task and multiple dual-task Timed Up and Go tests. The study examined whether rTMS could enhance cognitive abilities and improve motor-cognitive performance, which are commonly impaired in Parkinson\'s disease and contribute to reduced functional independence. Findings indicated that rTMS led to improvements in cognition, single-task mobility, and complex dual-task performance. The intervention was well tolerated, and no adverse events related to the stimulation intensity were reported.
