Directional hypokinesia: Prolonged reaction times for leftward movements in patients with right hemisphere lesions and neglect

Academic Article

Abstract

  • Patients with hemispatial neglect perform activities poorly in the hemispace contralateral to the lesion. We postulate that hemispatial neglect induced by right hemisphere lesions may be associated with a directional hypokinesia: initiation of movements toward the hemispace contralateral to the lesion is affected more than movements toward the lesion. We test ed 6 patients with hemispatial neglect caused by right hemisphere damage, 7 with left hemisphere damage and no neglect, and 12 controls. Patients with left hemispatial neglect initiated responses to left hemispace more slowly than toward right hemispace. © 1985 American Academy of Neurology.
