Dyslexia

Dyslexia, also known as reading disorder, is characterized by trouble with reading unrelated to problems with overall intelligence. Different people are affected to varying degrees. Problems may include difficulties in spelling words, reading quickly, writing words, "sounding out" words in the head, pronouncing words when reading aloud and understanding what one reads. Often these difficulties are first noticed at school. When someone who previously could read loses their ability, it is known as alexia. The difficulties are involuntary and people with this disorder have an unaffected desire to learn.
