Ask anyone you know what they  think of dyslexia and they will invariably answer by stating, “Isn’t that when you read upside down and backwards.” 
 
Well, I have assessed thousands of kids I believe are “dyslexic” and have yet to meet one reading upside down and backwards.
 
To clear up any confusion, stay with this researched based definition: 
 
Dyslexia is a specific learning disability that is neurological in origin.   It is characterized by difficulties with accurate and/or fluent word recognition, and by poor spelling and decoding abilities. These difficulties typically result from a deficit in the phonological component of language that is often unexpected in relation to other cognitive abilities and the provision of effective classroom instruction. Secondary consequences may include problems in reading comprehension and reduced reading experience that can impede growth of vocabulary and background knowledge   (NICHD).
 
Notice, there’s no mention of “upside down and backwards” in the definition.
 
Work hard to shake this notion out of your tree!
