How common are different kinds of learning and attention issues?

Converging epidemiological evidence indicates at least 1 in 5 children in the U.S. have learning and attention issues. Prevalence estimates vary for conditions such as dyslexia because different studies use different definitions. There is no blood test or other quick way to tell if a child has a learning or attention issue. An accurate diagnosis involves comprehensive assessment protocols that look at many kinds of behaviors and skills.
