phonological dyslexia
[ˌfəunəˈlɔdʒikəl dɪsˈleksi:ə]
Phonological dyslexia is a reading disability that is a form of Alexia (acquired dyslexia), resulting from brain injury, stroke, or progressive illness and that affects previously acquired reading abilities. The major distinguishing symptom of acquired phonological dyslexia is that a selective impairment of the ability to read pronounceable non-words occurs although the ability to read familiar words is not affected.
