Status dissociatus after surgery for tegmental ponto-mesencephalic cavernoma: a state-dependent disorder of motor control during sleep

Mov Disord. 2004 Jun;19(6):719-23. doi: 10.1002/mds.20027.

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.
