Dystonias
Key Points
Dystonias cause abnormal postures and/or twisting, jerky movements. Focal dystonias are common and usually begin during adulthood. Generalized dystonia may be inherited or secondary to another disorder or a drug. Diagnosis is clinical. Treat generalized dystonias with anticholinergic drugs and/or muscle relaxants; treat focal or segmental dystonias and generalized dystonias that affect mainly one body part with botulinum toxin injections.
