The three major symptoms of childhood ADHD — hyperactivity, impulsivity, and inattention — create many challenges for children who suffer from the disorder. These include problems performing at school, difficulty making and keeping relationships, and an inability to function comfortably or appropriately in social settings. But these symptoms may also have a silver lining. Hyperactivity can give your child the energy she needs to work longer and harder, impulsivity can provide the courage and drive your child needs to take great leaps of faith, and inattention can make it easier for your child to move between projects.
