(Alexia; Alexic Anomia; Word Blindness; Text Blindness; Visual Aphasia)

Alexic anomia happens when you lose your ability to understand written words. You can no longer read and name words. This is a type of receptive aphasia, which is a language disorder that involves difficulty understanding spoken or written language. It is caused by the brain not functioning correctly.
