  2. What Is Dyslexia? A neurodevelopmental reading disorder caused by subtle disturbance in brain structures and functions One type of specific learning disability Not caused by brain damage Not caused by low IQ © 2005-2007 Nemours BrightStart! Dyslexia Initiative. All rights reserved.

  3. What Is Dyslexia? Dyslexia is fundamentally a language-based disorder Not caused by a visual problem where the child’s eyes or brain “flip” letters People with dyslexia have difficulty analyzing and blending letter sounds within words, and building a large “bank” of easily recognized words © 2005-2007 Nemours BrightStart!

  4. Reading Is An Unnatural Act Humans are genetically and neurologically hard-wired for speech This is not true for reading which must be learned through conscious effort © 2005-2007 Nemours BrightStart! Dyslexia Initiative. All rights reserved.

  5. Evidence For The Neurobiological Basis Of Dyslexia Functional brain imaging studies have shown that dyslexic brains work differently than normal brains when reading occurs After intensive, appropriate remedial instruction, the dyslexic brains begin to function more like normal brains when reading © 2005-2007 Nemours BrightStart!

  6. How Prevalent Is Dyslexia? Estimates vary, but all indicate that very large numbers of children and adults are significantly poor readers About 17-20% of children experience serious reading problems An additional 20% struggle with reading © 2005-2007 Nemours BrightStart!

  12. Symptoms of Possible Dyslexia in Young Children Difficulty recognizing and writing letters in kindergarten Difficulty connecting letters to their sounds Difficulty breaking words into syllables (e.g., baseball into base and ball) Difficulty recognizing rhyming words © 2005-2007 Nemours BrightStart!

  13. Symptoms of Possible Dyslexia in Young Children Difficulty identifying words with the same beginning or ending sounds Difficulty reading simple words that can be sounded out (e.g., big, cat) Difficulty remembering common, irregularly spelled words (e.g., said, who) © 2005-2007 Nemours BrightStart!

  14. Symptoms of Dyslexia in Children 8 years and Up Persistent difficulty decoding one-syllable regular words and recognizing common, irregular words Difficulty reading small function words (e.g., of, that, to) Difficulty with spelling Mispronunciation of longer words © 2005-2007 Nemours BrightStart!
