dystonia

dys·to·ni·a

D0447775 (dĭs-tō′nē-ə)n. Abnormal tonicity of muscle, characterized by prolonged, repetitive muscle contractions that may cause twisting or jerking movements of the body or a body part.

dys·ton′ic (-tŏn′ĭk) adj.

dystonia

(dɪsˈtəʊnɪə) n (Pathology) a neurological disorder, caused by disease of the basal ganglia, in which the muscles of the trunk, shoulders, and neck go into spasm, so that the head and limbs are held in unnatural positions[from dys- + -tonia from Greek tonos tension, from teinen to stretch]

dys•to•ni•a

(dɪsˈtoʊ ni ə)

n. a neurological disorder marked by strong involuntary muscle spasms that cause painful and disabling twisting of the body. [1955–60] dys•ton•ic (-ˈtɒn ɪk) adj.

dystonia

Neurology Involuntary, often acute movement and prolonged contraction of one or more muscles, resulting in twisting body motions, tremor, and abnormal posture Etiology Inherited, ↑ during voluntary movement, nervousness, and emotional stress; dystonias may affect the extrapyramidal system–despite lack of demonstrable lesions, task specific–eg, writer's cramp or associated with medications–especially antipsychotics or disease–eg, a form of lung cancer Location Tongue, jaw, eyes, neck, trunk, extremities, occasionally the whole body Management Dopamine, sedatives–benzodiazepines–eg diazepam, anticholinergics–eg, trihexyphenidyl, benztropine–which cause dry mouth, mydriasis, urinary retention, and visual hallucinations; surgery. See Cranial dystonia, Dopa-responsive dystonia, Focal dystonia, Idiopathic torsion dystonia, Oromandibular dystonia, Segawa's dystonia, Torsion dystonia.

dys·to·ni·a

(dis-tō'nē-ă) A state of abnormal (either hypo- or hyper-) tonicity in any tissue, particularly skeletal muscle.
Synonym(s): torsion spasm. [dys- + G. tonos, tension]

dystonia

A group of muscle disorders featuring variable muscle tone, muscle spasms, abnormal posture or muscle contraction, or interference with normal movement. The dystonias include wry-neck (TORTICOLLIS), WRITER'S CRAMP, spasmodic closure of the eyelids (BLEPHAROSPASM) and involuntary grimacing and chewing movements (Meige syndrome). Dystonias may be of autosomal dominant or recessive or X-linked aetiology. Botulinum toxin treatment is effective in many cases.

Dystonia

A movement disorder characterized by sustained muscle contractions that result in writhing or twisting movements and unsual body postures.Mentioned in: Huntington Disease, Schizophrenia
