Dyslexia, or word blindness, is a learning disability that affects reading.[1][2] Different people are affected to different degrees. The condition that makes it difficult to learn and understand things in the same way others do. It is a very common problem.
Dyslexia affects the way the brain understands words. The most common signs of dyslexia are reading and writing problems.[3]
Estimates are that in the United States between 5 and 9% of school children have dyslexia. Another source says it affects 3–7% of the population.[4] Up to 20% of the general population may have some degree of symptoms.[5] While dyslexia is more often diagnosed in boys, this is partly explained by a self-fulfilling referral bias among teachers and professionals.[6]
