Spasmodic Dysphonia
Spasmodic dysphonia, also known as laryngeal dystonia, is a rare neurological disorder characterized by involuntary muscle spasms of the larynx (voice box). Spasmodic dysphonia causes the voice to break, or to have a tight, strained or strangled quality. Patients with spasmodic dysphonia may have difficulty communicating clearly. The disorder appears most often in people between 30 and 50 years of age, and more frequently in women. While the exact cause of spasmodic dysphonia is not always known, it is sometimes due to psychological stress, however, most cases result from a problem in the brain and nervous system. Spasmodic dysphonia is often a chronic condition.
