Paroxysmal alexia.
This report describes a case of paroxysmal alexia which progressed to a persistent syndrome of alexia without agraphia. The sequence of symptoms beginning with a sensation of eyeball movement followed by blurred vision in the affected eye, alexia and diminished awareness strongly implicates an ictal mechanism. Anatomical, physiological and psychological considerations suggest that the syndrome arose from functional disruption between the visual cortex and the dominant inferior parietal cortex.
