When do signs of ADHD first appear?

Donna Hill Howes, RN
Family Medicine
According to the American Academy of Pediatrics, people are born with a predisposition toward having attention deficit hyperactivity disorder (ADHD). Symptoms may first appear in the preschool years; although, they may not appear problematic at that time. Many children in the toddler and preschool years behave impulsively, hyperactively, and have short attention spans. But once children reach elementary school, they are expected to behave in certain, proper ways. Most children are able to sit still, listen to adults, and follow directions well by age 6. Children who continue to display symptoms of impulsivity, hyperactivity, and inattention in the elementary years and beyond may be referred for ADHD testing and treatment.
