Specific symptoms vary and may be more apparent in some children than others. The study doctor or your child’s regular healthcare provider will evaluate your child’s symptoms to determine if he or she has ADHD.
ADHD is usually categorized into three types: inattentive ADHD, hyperactive ADHD, or combination ADHD.

Children with combination ADHD show symptoms characteristic of both inattentive and hyperactive ADHD.
