There's a common misconception about dyslexia - that it involves "backward reading" or "mirror reading". Reversing letters isn't always a sign of dyslexia, and a lot of little kids who don't have the disorder write their letters backwards, too.

Instead, dyslexia is an "unexpected difficulty in reading for an individual who has the intelligence to be a much better reader," according to the Yale Center for Dyslexia & Creativity.
