Dystonia is a condition that causes your muscles to spontaneously contract, or movement without control. Examples include: uncontrolled blinking, repetitive twisting of your head, and voice changes (e.g. whispering or soft voice). Dystonia can be caused by dysfunction in nerve cell communication, or the way your brain communicates with your muscles, as well as other disease such as Parkinson's disorder, Huntington's disease, strokes, brain tumors. Side effects of dystonia include pain, difficulty with jaw movement or functional blindness. Treatment for dystonia can include oral medications, physical therapy,speech therapy, brain stimulation.
