A Preliminary Report on Disordered Speech with Deep Brain Stimulation in Individuals with Parkinson's Disease

A Preliminary Report on Disordered Speech with Deep Brain Stimulation in Individuals with Parkinson's Disease

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has proven effective in treating the major motor symptoms of advanced Parkinson's disease (PD). The aim of this study was to learn which laryngeal and articulatory acoustic features changed in patients who were reported to have worse speech with stimulation. Six volunteers with PD who had bilateral STN electrodes were recorded with D...

Speech in Individuals with Parkinson’s Disease with and without Deep Brain Stimulation

Speech is a complex behavior that is coordinated by an integrated network of sensory, muscular, respiratory, and cognitive systems. As a result of the complex nature of speech, symptoms of speech impairment can be quite diverse, reflecting dysfunction in one or more of these systems. Research has found that speech problems are common in Parkinson’s disease (PD), and it has been found that 70% o...

Relationship of the P Angle with Stereotactic Arc in Intraoperative Outcome of Patients with Parkinson’s Disease Undergoing Deep Brain Stimulation

Background & Aim: DBS (deep brain stimulation) is a new and successful technique in treatment of symptoms of Parkinsonism especially after drug resistance. Research in this field is mostly designed for evolution of this technique. The present study aimed at evaluating the relationship between the angle formed in midsagittal and STN (sub-thalamic nucleus) axis line and recording l...

Effects of deep brain stimulation on speech in patients with Parkinson’s disease and dystonia

Deep Brain Stimulation of the Subthalamic Nucleus Improves Lexical Switching in Parkinsons Disease Patients

OBJECTIVE Reduced verbal fluency (VF) has been reported in patients with Parkinson's disease (PD), especially those treated by Deep Brain Stimulation of the subthalamic nucleus (STN DBS). To delineate the nature of this dysfunction we aimed at identifying the particular VF-related operations modified by STN DBS. METHOD Eleven PD patients performed VF tasks in their STN DBS ON and OFF conditio...
