 Individuals with deep dyslexia experience both semantic paralexia (para-dyslexia) and phonological dyslexia, which causes the person to read a word and then say a related meaning instead of the denoted meaning. Deep alexia is associated with clear phonological processing impairments. Deep dyslexia is caused by widespread damage to the brain that often includes the left hemisphere. The "continuum" hypothesis claims that deep dyslexia develops from phonological dyslexia.
