Language of illiterate subjects
Illiteracy due to social reasons is a common fact around the world. The first concepts about aphasia in the 19th century were based on observations done in patients not always literate but the fact was never considered important.
Our findings suggest that the brain organization of illiterate subjects differs from that of those that attended school in the proper age and this must have impact on the signs of aphasia.
