ADHD, which stands for attention deficit hyperactivity disorder, causes abnormal hyperactive and impulsive behaviors. At least 4.4% of Americans have ADHD, and 5.3% of people have it worldwide. Both adults and children can get it; 85% of children with ADHD carry it into adulthood, according to the Centers for Disease Control.

At least 6.4 million children in America have ADHD. And although many adults have the disorder, only 10.9% seek treatment. The diagnoses for ADHD have only increased over the past two decades, says psychiatrist Dr. John T. Walkup.
