AB We studied a 70-year-old woman with a unique combination of hyperkinesia and mutism. These findings differed from akinetic mutism because there was continuous bilateral ballism and dystonia—hence the term “hyperkinetic mutism.” CT demonstrated bilateral calcifications in the basal ganglia, and MRI indicated bilateral watershed infarcts. Different dopaminergic mechanisms may underlie the hyperkinesia and mutism.
