True use of aphasia: has no language. Actual use of aphasia: has some language, 30% show recovery of these aphasic symptoms. However, these that showed recovery were either left handed or ambidextrous. Right hemisphere damage: most patients showed few aphasic symptoms, very rarely leads to complete aphasia. Those that showed aphasic problems were always left handed or ambidextrous. Right handed individuals do not show symptoms with right hemisphere damage: clear that right handed individuals only had problems with left hemisphere damage. Only lose language to left hemisphere damage: recovery. Left handed people show excellent recovery from damage. Suggesting left handed people have language in both hemispheres. Damage to either hemisphere has equal probability of affecting language (producing aphasic symptoms: conclusion, some language on both sides in children.
