Dyslexia is the most common learning disability, affecting up to 20% of the population. 

Some people are more affected than others.

The basis of dyslexia is difficulty reading.

Dyslexia is NOT a problem of letter reversals, although this can be a symptom.

Dyslexics have difference in the area of their brain that associates the shape of the letter with the sound of the letter.

Often, dyslexics have difficulty with rapid word recall and rapid word recognition.

Dyslexia is more than a reading problem.
