Dyslexia
Etiology of Dyslexia
Aural, rather than visual, problems are now thought to be the predominant causes of reading disabilities. Phonologic processing problems cause deficits in discrimination, blending, memory, and analysis of sounds. Dyslexia may affect both production and understanding of written language, which is often restricted further by problems with auditory memory, speech production, and naming or word finding. Underlying weaknesses in verbal language are often present.
