SD is another mysterious voice disorder, the cause is yet unknown.

Because the voice can sound normal at times, spasmodic dysphonia was once

thought to be psychogenic, but as reported by NIDCD ( The National Institute of

Deafness and other Communication Disorders), research has revealed increasing

evidence that most cases of spasmodic dysphonia are in fact neurogenic and may

co-occur with other movement disorders such as blepharospasm (excessive eye

blinking and involuntary forced eye closure), tardive dyskinesia (involuntary

and repetitious movement of muscles of the face, body, arms and legs),

oromandibular dystonia (involuntary movements of the jaw muscles, lips and

tongue), torticollis (involuntary movements of the neck muscles), or tremor

(rhythmic, quivering muscle movements).

NIDCD also reports that spasmodic dysphonia

may run in families and is thought to be inherited. Research has identified a

possible gene on chromosome 9 that may contribute to the spasmodic dysphonia

that is common to certain families. Spasmodic dysphonia can affect anyone

between 30 and 50 years of age. More women appear to be affected by spasmodic

dysphonia than are men.

Treatment for SD?

The “triangle” ENT –Neurologist – SLP is

usually on the front line in diagnosing and treating the symptoms of SD. There

is presently no known cure for spasmodic dysphonia. Current treatments only

help reduce the symptoms.

SLP-

Voice therapy may reduce some symptoms, especially in mild cases. Voice Therapy

and Vocal Cords special physiotherapy may also support a better voice while

undergoing the post effects of treatment of choice – see below.
