Dyslexia FACTS

According to the New England Journal of Medicine

 "Developmental Dyslexia is characterized by an unexpected difficulty in reading for children and adults who otherwise possess the intelligence, motivation, and schooling considered necessary for accurate and fluent reading."

According to the National Institutes of Health

 "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."

Medical FACTS (Not Fiction!)

  • 1 out of 5 people suffer from dyslexia (See Yale Study).

  • Only 30% of dyslexics have difficulty with reversing letters and numbers.

  • Dyslexics do not "see" words backwards.  Difficulty with word reversals are related to issues with sequential working memory.

  • Dyslexia is a specific neurological condition that can be seen on a functional MRI that shows brain usage patterns (See Yale Study). Dyslexics have been shown to use the left and right front portions of their brains to read, while non-dyslexics use the left front and right back parts of their brains to read.

  • Dyslexia affects a person's ability read and spell accurately because of memory and/or phonological awareness deficits and therefore requires cognitive and phonological therapy to treat.

  • Dyslexia is evenly distributed among all ethnic, social, gender demographics.

  • Dyslexia is equally prevalent in non-English languages.

  • Dyslexia, like hypertension, can vary in severity.

  • No cure for dyslexia is known and it is not outgrown.

  • ALL dyslexics are of average or above average intelligence.

  • Dyslexia and AD/HD are closely related and often mistakenly confused (see AD/HD) .

  • Dyslexia can be concurrent with deficits in visual-motor integration, visual perception, eye-tracking, and working memory.

Academic FACTS (Not Fiction!)

  • Dyslexia can't be effectively treated using traditional reading or tutoring programs, which tend to stabilize low reading achievement levels instead of eliminating them. 

  • Dyslexia is not a catchall phrase for all reading or learning disabilities.

  • Dyslexia is NOT simply about reversing letters and numbers, in fact, only a fraction of dyslexics exhibit this characteristic.

  • Dyslexia does NOT reduce or otherwise affect a person's ability to learn, comprehend or acquire knowledge through non-written medias.  However, low reading skills obviously affect a person's ability to achieve where reading is required.

  • 80% of children labeled learning disabled are really dyslexic. (see Specific LD)

  • All but the most severe dyslexics can learn to read at or above grade level.

  • Dyslexia can affect a persons ability to perform at expected levels even after they learn to read at grade level due to continued deficits in working memory, visual perception, and visual-motor integration.
