General Discussion

Spasmodic dysphonia is a voice disorder characterized by momentary periods of uncontrolled vocal spasms, tightness in the throat, and/or recurrent hoarseness. At certain times, affected individuals must make a conscious effort to speak. The most frequent sign of this disorder is a sudden, momentary lapse or interruption of the voice. Spasmodic dysphonia is a form of dystonia, a group of neurological movement disorders characterized by involuntary muscle spasms.

There are two types of spasmodic dysphonia: Abductor spasmodic dysphonia and the more common adductor spasmodic dysphonia. The cause of spasmodic dysphonia is not known.
