Dyslexia
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]
Characteristics
A person can have dyslexia even if they are intelligent. Their education might be affected by their dyslexia or not. Recent studies show there are some small business owners that have dyslexia. Researchers think many dyslexic entrepreneurs are successful because they can delegate responsibilities (of writing letters) and still be good at speaking.[7]
At the end of the 19th century,[8] scientists did a lot of research about dyslexia and found some of the reasons that people are dyslexic.
Therapy
Children with dyslexia can be helped. One way teachers help dyslexic students is to break words into different sounds.[9] The student must learn how to write the different sounds and create words. This helps with reading and writing.[10]
Origins
Speech is a newcomer in evolutionary terms.[11][12] Like the large heads of babies, human speech evolved very recently.[13][14]
Newer biological functions tend to be less reliable than older functions.[15]
