An inability to perform transitive or intransitive gestures on command. Performance may or may not improve with imitation or with the actual object. A common error is using a body part as an object (or tool) in which part of the hand forms part of the object (tool) being demonstrated. Movements commonly used to assess ideomotor apraxia include the pretended use of common objects (e.g., hammer, scissors, key) and symbolic gestures (e.g., saluting, making the thumb-out gesture of a hitchhiker). Ideomotor apraxia is generally associated with left hemisphere lesions (inferior parietal lobe or supplementary motor area) or a lesion of the corpus callosum. Ideational apraxia and ideomotor apraxia frequently coexist.

The second case study of hemispheric disconnection after CHI was published 40 years later (Schott, Michel, Michel, & Dumas, 1969), but there was no anatomic confirmation of injury to the callosum. The authors described tactile anomia, ideomotor apraxia, and agraphia confined to the left hand. A case of posttraumatic disconnection syndrome with neuropathologic verification was found to evidence ideomotor apraxia and agraphia confined to the left hand (Rubens, Geschwind, Mahowald, & Mastri, 1977). Neuropathologic findings showed marked thinning of the corpus callosum with demyelination and loss of axons.
