Additional Information:

This type of aphasia almost always reflects damage to cortex that is supplied by cortical MCA branches. Note that the basilar artery supplies both sides of the brainstem, thus partial occlusion might affect either or both sides of the brainstem and produce hemiplegia or quadriplegia by affecting one or both of the pyramidal tracts.
