Voice dystonia (the medical term is laryngeal dystonia and also sometimes spasmodic dysphonia) is a rare voice disorder caused by involuntary muscle contractions supplying the vocal cords. It is believed to be the result of incorrect messages from the brain to the muscles in the throat. Symptoms usually appear between the ages of 30 and 50 but it does sometimes affect younger or older people.
Signs of laryngeal dystonia are:
- A strained voice sometimes with a tremor. It becomes an effort to speak.
- The voice has a strangled quality and/or a feeling of choking on words.
- Alternatively, the voice can be breathy, whispering or very quiet. It becomes a struggle to project the voice especially in noisy environments.
If the symptoms above appear, the right course of action is for the GP to make a referral to an ear, nose and throat surgeon specialising in laryngeal dystonia. As laryngeal dystonia is so rare, it is likely that a GP will not have encountered a patient with this condition.
Generally, if laryngeal dystonia starts in adulthood, the dystonia affects only the voice. If it spreads at all, which is unlikely, it is usually only to one other area.
Treatment usually involves regular injections. Some people might also benefit from speech therapy. It is very much an individual experience.
