ADHD often begins in childhood. But it may continue into the adult years. ADHD is diagnosed more often in boys than in girls.
It is not clear what causes ADHD. It may be linked to genes and home or social factors. Experts have found that the brains of children with ADHD are different from those of children without ADHD. Brain chemicals are also different.
ADHD symptoms fall into three groups:
