What is Spasmodic Dysphonia
Spasmodic dysphonia (SD), a focal form of dystonia, is a neurological voice disorder that involves involuntary "spasms" of the vocal cords causing interruptions of speech and affecting the voice quality. SD can cause the voice to break up or to have a tight, strained, or strangled quality.
