Speech and Voice Outcomes Following HD-tDCS Over the Left SMA

Pharmaceutical and neurosurgical treatments reliably ameliorate the cardinal motor symptoms in PD but, they often yield inconsistent outcomes for speech and voice disorders, with some studies showing exacerbation of pre-treatment deficits. Therefore, it is crucial to develop and optimize novel approaches that could simultaneously improve speech and voice deficits in PD and facilitate existing behavioral interventions. This project will investigate the immediate and short-term effects of multiple sessions of HD-tDCS over the left SMA on speech and voice deficits in PD.
