| chorea | Mature onset disease characterised by progressive loss of neuronal functioning. Caused by unstable amphlification of a trinucleotide (CAG)n repeat with the coding region of a gene encoding a 348 kD, widely exposed product. (18 Nov 1997) |
|---|---|
| chorea-acanthocytosis | A slowly progressive familial chorea with associated mental deterioration, diminished deep tendon reflexes, bilateral atrophy of the putamen and caudate nuclei and acanthocytosis (thorny appearance of blood erythrocytes); the disorder typically begins around late adolescence; inheritance is usually autosomal recessive. Synonym: acanthocytosis with chorea. (05 Mar 2000) |
| chorea cordis | Cardiac irregularity related to chorea. (05 Mar 2000) |
| chorea dimidiata | Chorea involving the muscles on one side only. Synonym: chorea dimidiata, hemilateral chorea. (05 Mar 2000) |

| chorea major | A spasmodic attack occurring in patients with conversion hysteria. (05 Mar 2000) |
| chorea minor | A postinfectious chorea appearing several months after a streptococcal infection with subsequent rheumatic fever. The chorea typically involves the distal limbs and is associated with hypotonia and emotional lability. Improvement occurs over weeks or months and exacerbations occur without associated infection recurrence. Synonym: acute chorea, chorea minor, chorea, juvenile chorea, rheumatic chorea, Sydenham's disease. (05 Mar 2000) |
| chronic progressive chorea | A progressive disorder usually beginning in young to middle age, consisting of a triad of choreoathetosis, dementia, and autosomal dominant inheritance with complete penetrance. Bilateral marked wasting of the putamen and the head of the caudate nucleus is characteristic. Synonym: chronic progressive chorea, degenerative chorea, hereditary chorea, Huntington's disease.

| mimetic chorea | Imitation of the chorea movements of another person. (05 Mar 2000) |
| Morvan's chorea | Continuous involuntary quivering or rippling of muscles at rest, caused by spontaneous, repetitive firing of groups of motor unit potentials. Synonym: fibrillary chorea, kymatism, Morvan's chorea. Origin: myo-+ G. Kyma, wave (05 Mar 2000) |
| habit chorea | <clinical sign> An involuntary compulsive, repetitive, stereotyped movement, resembling a purposeful movement because it is coordinated and involves muscles in their normal synergistic relationships, tics usually involve the face and shoulders. (18 Nov 1997) |
| posthemiplegic chorea | A unilateral athetosis involving hemiplegic limbs, usually seen in children. Synonym: posthemiplegic chorea. (05 Mar 2000) |
| saltatory chorea | Rhythmic dancing movements, as in procursive chorea. (05 Mar 2000) |
| procursive chorea | A form in which the patient whirls around, runs forward, or exercises a sort of rhythmic dancing movement. Synonym: dancing chorea. (05 Mar 2000) |
| hemilateral chorea | Chorea involving the muscles on one side only. Synonym: chorea dimidiata, hemilateral chorea. (05 Mar 2000) |
