Markedly asymmetrical parkinsonism as a leading feature of adult-onset Huntington's disease



We report on a 28-year-old man who presented with right hand tremor, bradykinesia, and rigidity of his right side extremities. Our case report emphasizes that markedly asymmetrical parkinsonism can be an initial presentation of adult-onset Huntington's disease (HD), and different clinical presentations can be observed in members of an individual HD family with the same CAG repeat length. © 2004 Movement Disorder Society
