Tsuboi T, et al. - A 1-year follow-up study of Parkinson’s disease (PD) patients treated with subthalamic nucleus deep brain stimulation (STN-DBS) was performed to assess early speech and voice disorders. Findings revealed that the most common DBS-induced speech and voice disorders were strained voice and spastic dysarthria and that STN-DBS potentially aggravates stuttering and breathy voice. An improved understanding of these types of disorders might help detect speech and voice deteriorations during the early phase and result in appropriate treatments.
