Assessment of Reading

 
 

Overview

  • Show the patient a list of words and ask them to read the words out loud, or ask them to read a few sentences from a newspaper.
    • Interpretation

    • Pure alexia: reading of words letter-by-letter.
    • Surface dyslexia: ability to phonetically sound out words (breed, steam), but difficulty reading words with irregular spelling (debt, colonel, broad, steak).
    • Phonological dyslexia: inability to read non-words (neg, bluck, deak) with otherwise normal reading of words.
    • Deep dyslexia: semantic errors (e.g. reading the word ‘table’ as ‘chair’ or ‘street’ as ‘road’), and inability to read plausible non-words (neg, bluck, deak).Stroke, traumatic brain injury
    • Neglect dyslexia: the patient omits or substitutes part of a word, especially at the beginning of the word. For example, island / land or fish / dish.Dominant hemispheric damage
    • Note

    • The term ‘dyslexia' is colloquially used to denote ‘developmental dyslexia', which is a global difficulty in reading beginning in childhood that may progress to adulthood. The dyslexias identified above are specific defects that are generally acquired rather than developmental.
