Abstract

After surgery for a tegmental ponto-mesencephalic cavernoma, a patient developed sleep-related excessive fragmentary myoclonus, diffuse myoclonic jerks, simple quasipurposeful movements of the limbs, and rapid eye movement (REM) sleep behaviour disorder as motor features of status dissociatus, a condition in which elements of one state of being (wake, NREM and REM sleep) pathologically intrude into another. © 2004 Movement Disorder Society
