While the inherent cause of dyslexia is not known , it seems to be genetically linked . About 40 percent of siblings with dyslexia have the same reading issues . And as many as 49 percent of parents who have kids with dyslexia have it too .
Signs and symptoms :
A key sign of dyslexia in kids is something called phonemic awareness . Many kids who become diagnosed with dyslexia have trouble matching letters to sounds , preventing them from reading fluently . While this problem can be detected as early as preschool , in other kids , dyslexia isn ’ t picked up until later on when they have trouble with more complex skills like grammar , reading comprehension , reading fluency , sentence structure and more in-depth writing . Here are more specific signs and symptoms broken out by grade level :
Preschool : Trouble recognizing whether two words rhyme , taking away the beginning sound from a word , learning new words , trouble recognizing letters and matching them to sounds .
Grade School : Trouble taking away the middle sound from a word or blending several sounds to make a word , can ’ t recognize common sight words , quickly forgets how to spell many of the words she studies , gets tripped up by word problems in math .
Middle School : Makes many spelling errors , frequently has to re-read sentences , reads at a lower academic level .
High School : Often skips over small words when reading , doesn ’ t read at the expected grade level , prefers multiplechoice over fill in the blank .
