ADHD: What to Look For

ADHD behaviors usually become apparent when a child is between 3 and 6 years of age. Hyperactive or impulsive behaviors, which are often noticed first, include fidgeting, an inability to sit still, excess energy, verbal outbursts, extreme impatience, talking incessantly, and interrupting others. The inattentive behaviors often become noticeable only when a child enters school. He might be easily distracted, have difficulty following instructions, be unusually forgetful, struggle with organizing tasks, avoid things that involve mental exertion, and appear oblivious to what’s going on around him.

Boys are diagnosed with ADHD much more frequently than girls, at a rate of about 2 to 1, though girls experience the disorder differently.
