Callosal Apraxia

Callosal apraxia is manifested by the inability to perform previously learned movements. This kind of apraxia, or motor neurological disorder, is caused by a damage in the corpus callosum which is the primary linkage between the left and right hemispheres of the brain. This is most common among the elderly who have had brain tumors or strokes. For instance, a patient who has just suffered from an ischemic stroke may not be able to perform simple tasks such as buttoning, cooking, and typing.
