Classification There are several types of<unk>  that affect different areas of the body. However, it is unknown if the gene that causes Early Onset<unk>  is responsible for the other dystonias as well. * Cervical dystonia (spasmodic torticollis): A type of dystonia that affects the head, neck and spine. It can create problems by the characteristic turning of the head and neck from side to side. * Blepharospasm: This type of dystonia causes involuntary contraction of the eyelids. The main concern for this dystonia is that it can cause the eyelids to close involuntarily and for indefinite periods of time. * Oromandibular dystonia: A dystonia of the jaw, lips, and/or the tongue. It can make eating and swallowing very complicated due to the jaw being held open or shut for periods of time. * Spasmodic dysphonia: A dystonia of the vocal cords. The complications surrounding this form of dystonia are speech related and can cause symptoms such as speech that wavers, speech that sounds like a whisper, or speech that is hesitant. * Writer's cramp (occupational dystonia): A dystonia that affects the muscles of the hand and forearm. It is triggered by attempting to write or execute other fine-motor hand functions. * Orofacial-Buccal dystonia (Meige's or Brueghal's Syndrome): A combination of blepharospasm and oromandibular dystonia. * Early-onset<unk> : The most severe type of dystonia, it begins in an arm or leg and progresses to the rest of the body until the person — in most cases, a child — is confined to a wheel chair.
