Patients with Parkinson’s Disease (PD) experience both motor and speech difficulties, with several patients also developing neurogenic stuttering. Deep Brain Stimulation (DBS) has been shown to be an effective intervention to reduce motor difficulties, but its effect speech disfluencies are not yet clear. In this poster, we review the literature examining the effects of DBS on disfluent speech in patients with PD, with the goal of identifying factors that may predict the therapeutic outcome of DBS for PD patients with neurogenic stuttering.
