Acquired alexia is a reading disorder caused by neurological damage and is usually the result of small, left-hemisphere, inferior parietal lobe lesions involving the angular gyrus

small, left-hemisphere, inferior parietal lobe lesions involving the angular gyrus. It is often associated with aphasia and there appears to be some relationship between the severity and nature of aphasic auditory comprehension problems and the severity and nature of alexia. The variables effecting comprehension include word frequency, part of speech, emotionality, personal relevancy, syntactic complexity and length and degree of inference required for interpretation. Individuals with acquired alexia can be classified into four groups: deep alexia, surface alexia, phonological alexia and pure alexia. Error patterns, as they relate to semantics, orthographic length and word frequency distinguish the types of acquired alexia. Some have suggested that phonological alexia is on the continuum of deep alexia (Friedman1).
