Brain pathology is frequently associated with alexia, a disturbance in reading ability. Four types of alexia have been described: alexia without agraphia, alexia with agraphia, spatial alexia, and frontal alexia. Excepting spatial alexia, acquired reading disturbances are associated with left hemisphere pathology – usually strokes, tumors, or traumas. Rehabilitation is usually carried out simultaneously with aphasia rehabilitation.
