Is spasmodic dysphonia a form of dystonia?
Yes, spasmodic dysphonia is a focal form of dystonia. Dystonia is the general neurological term for a variety of problems characterized by excessive contraction of muscles with associated abnormal movements and postures. Other focal dystonias include blepharospasm (involving the eyelids), oromandibular dystonia, (involving the jaw and tongue), cervical dystonia or spasmodic torticollis (involving the neck), and writer’s cramp (involving the hand). These forms of dystonia may appear in combination with spasmodic dysphonia.
