Hemiakinesia and ideomotor apraxia: A disconnection case report

Abstract

Background: lnterhemispheric connections between the homolog cortical areas are performed by the projections in the corpus callosum. Callosal disconnection findings such as pure alexia, optic aphasia, color anomia, pure word deafness, and idiomotor apraxia may be seen when corpus callosum and/or paracallosal white matter damaged. lnvolvement of corpus callosum is quite rare in stroke but especially embolic infarction of the pericallosal and/or callosomarginal branches of the anterior cerebral and splenial branches of the posterior cerebral arteries may cause callosal disconnection syndromes.Case: A 66 year-old right handed man admitted to our clinic because of weakness in the left side. Neurological examination reveals central facial palsy, mild hemiparesia, tactil anomia, visual extinction, and grasping reflex in the left side. The patient could move his left arm and leg spontaneously but not performed with command. Cranial magnetic resonance imaging showed right callosal infarction. Discussion: Extremity apraxia could be seen in stroke patients due to lesions in the parietal or frontal cortical areas. In this article, we report a case of idiomotor apraxia and hemiakinesia after callosal infarction that rarely involved in stroke patients.
