Disturbed voluntary motor activity in schizophrenic disorder

Abstract

Synopsis Although motor features associated with schizophrenic disorders have been reported often, they have never been well understood and, since the introduction of neuroleptic drugs, they have been largely neglected. We report that disturbed voluntary motor activity occurs frequently among schizophrenics, is especially associated with features of formal thought disorder, but also with affective blunting, neurologic ‘soft’ signs. Certain motor and thinking abnormalities in schizophrenics may have a common pathogenetic basis.
