Hemiparkinsonism
Hemiparkinsonism
Hemiparkinsonism describes the finding of parkinsonian signs restricted to one side of the body, most usually akinesia, in which case the term hemiakinesia may be used. Idiopathic Parkinson’s disease may present with exclusively or predominantly unilateral features (indeed, lack of asymmetry at onset may argue against this diagnosis) but persistent hemiparkinsonism, particularly if unresponsive to adequate doses of levodopa, should alert the clinician to other possible diagnoses, including corticobasal degeneration or structural lesions.
