Brainstem pathology in spasmodic dysphonia.
Spasmodic dysphonia (SD) is a primary focal dystonia of unknown pathophysiology, characterized by involuntary spasms in the laryngeal muscles during speech production. We examined two rare cases of postmortem brainstem tissue from SD patients compared to four controls. In the SD patients, small clusters of inflammation were found in the reticular formation surrounding solitary tract, spinal tri...
متن کاملMorell Mackenzie's Contribution to the Description of Spasmodic Dysphonia.
OBJECTIVES Since the middle of the 20th century, most discussions of spasmodic dysphonia (SD) reference a paper by Ludwig Traube published in1871 as the first historical citation, crediting him with priority for this clinical syndrome. However, our recent research has determined that the original observation by Traube was published in 1864 and does not in fact describe what is currently recogni...
متن کاملConsideration of genetic contributions to the risk for spasmodic dysphonia.
Spasmodic dysphonia, a form of the neurologic condition known as dystonia, results from involuntary spasms of the larynx, producing interruptions of speech and changes in voice quality. The pathogenesis of spasmodic dysphonia is not well understood. However, several genetic mutations have been identified that cause different forms of dystonia. In some individuals, these genetic mutations result...
متن کاملTremor in speakers with spasmodic dysphonia
the objective of this work is the estimation of vocal tremor in patients with spasmodic dysphonia before and after treatment, and the comparison of their tremor characteristics with those estimated from healthy speakers. as an outcome, a new tremor attribute is introduced, the deviation of the modulation level and a novel method is proposed for classifying speakers according to the prevalence o...
متن کاملAbnormal structure-function relationship in spasmodic dysphonia.
Spasmodic dysphonia (SD) is a primary focal dystonia characterized by involuntary spasms in the laryngeal muscles during speech production. Although recent studies have found abnormal brain function and white matter organization in SD, the extent of gray matter alterations, their structure-function relationships, and correlations with symptoms remain unknown. We compared gray matter volume (GMV...
