Clinical Information
  • A cognitive disorder characterized by an impaired ability to comprehend written and printed words or phrases despite intact vision. This condition may be developmental or acquired. Developmental dyslexia is marked by reading achievement that falls substantially below that expected given the individual's chronological age, measured intelligence, and age-appropriate education. The disturbance in reading significantly interferes with academic achievement or with activities of daily living that require reading skills. (from dsm-iv)
  • A learning disorder characterized by an impairment in processing written words. Reading difficulties can include distortions, omissions or substitutions of characters. Oral and silent reading difficulties can include faulty and slow comprehension.
  • A learning disorder marked by impairment of the ability to recognize and comprehend written words.
  • Condition characterized by deficiencies of comprehension or expression of written forms of language.
  • Inability or difficulty reading, spelling, or writing words despite the ability to see and recognize letters; a familial disorder with autosomal dominant inheritance that occurs more frequently in males.
  • Reading disorder involving an inability to understand what is read. Less severe than alexia.
