Abstract
We studied a patient with severe on-off phenomena that complicated chronic L-dopa treatment of Parkinson disease. Neuropsychologic testing was performed in both the on and the off states. Compared with the profound changes in motor status, the neuropsychologic alterations were modest: general disinhibition of language, worsened memory, and perseveration.Keywords
