As many as one in ten children are diagnosed with attention deficit hyperactivity disorder (ADHD) in the U.S. each year. Behavioral problems associated with ADHD include inattention, hyperactivity and impulsiveness. Children can begin exhibiting these signs as early as 2 or 3 years of age and the earlier you begin treatment, the better the outcome for your child.

As parents, we know our children best, but it can be difficult to differentiate between normal childhood behavior and ADHD, and many parents worry about having to medicate their kids. If it goes untreated ADHD can seriously impact your child’s ability to learn and interact with others. However, medication is only one treatment and isn’t always necessary. Education, behavior therapy, proper nutrition, and support at home can all help control symptoms.

The key to treating ADHD in children, is recognizing the symptoms and speaking with your pediatrician. Here is a list of 15 signs your child may have ADHD.
