Chorea
Chorea is made up of irregular, random movements of various parts of the body. These are random and unpredictable involuntary movements that are short, fast and usually torsional. They are most often on acres of limbs and in the orofacial area. They usually intensify in movement, speech and emotions. A typical example is the characteristic dance walk. [1]
Etiology[edit | edit source]
Striatal damage (especially putamen), which causes predominance of dopaminergic neurotransmission.
Causes[edit | edit source]
Metabolic, toxic and drug effects.
Symptom[edit | edit source]
Chorea occurs regularly in the following diseases:
- Huntington's chorea
- Dopaminergic dyskinesia
- Parkinson's disease
- Focal lesions of the [[BG|basal ganglia] (perinatal encephalopathy)
- Striatal damage in streptococcal infection
- Chorea in pregnancy
Choreatic movements in Huntington's disease[edit | edit source]
Treatment[edit | edit source]
Antidopaminergic treatment with neuroleptics.[1]
