Cortical-Subcortical Interaction in Parkinson’s Disease
The ability to speak involves a complex brain system that is not fully understood. Parkinson's disease can interfere with the ability to speak. This research is studying the effects of Parkinson's Disease and a form of treatment known as Deep Brain Stimulation (DBS) of an areas o...
Imaging Genetics of Spasmodic Dysphonia
The purpose of this research study is to investigate changes in the brain associated with genetic risk factors in patients with spasmodic dysphonia compared to healthy volunteers. Those eligible will be healthy right-handed native English speaking volunteers between 21 and 80 yea...
Biomarkers of primary focal dystonias: structural-functional interactions
The purpose of this study is to better understand the brain changes and genetic risks in patients with different types of primary focal dystonia (laryngeal dystonia singer’s dystonia pianist’s dystonia embouchure dystonia oromandibular dystonia writer’s cramp cervical dystonia an...
Voice Tremor in Spasmodic Dysphonia: Central Mechanisms and Treatment Response
The purpose of this study is to better understand the brain changes in patients with spasmodic dysphonia (SD) and voice tremor (VT) and how these brain changes can be improved when given sodium oxybate Xyrem. SD and VT are both neurological disorders that affect voice production....
Role of Neurotransmission and Functional CNS Networks in Spasmodic Dysphonia and Other Focal Dystonias
The long terms purpose of this study is to better understand how the brain controls speech in patients with spasmodic dysphonia. Recent studies have found changes in brain function in patients with spasmodic dysphonia which may play an important role in the development of this di...
Brain sensorimotor reorganization as a predictor of clinical outcome following laryngectomy
The purpose of this study is to better understand the brain changes in patients who undergo total laryngectomy. Total laryngectomy is a commonly performed procedure for advanced head and neck cancer that radically changes the anatomy of the upper airway and leads to the loss of n...
