Children with ADHD are very energetic. However, high energy alone is not an indicator of ADHD. In fact, in some forms of ADHD, children have zero energy. For example, ADD may manifest itself in low energy and inattentiveness.
In order to qualify for the ADHD diagnosis, a child must have a chronic, pervasive problem with his or her ability to regulate activity level, along with impairment in their ability to inhibit and control impulses. This impairment of normal functioning or learning is the key to differentiating ADHD from normal activity.
How to Tell the Difference
For kids with ADHD, there might be additional impairments apart from hyperactivity that may not be as obvious. For example:
If you’ve got an energetic child who finds it difficult to sit still, he may be displaying some of the signs of ADHD. But if the child is able to control his impulses, emotions, pay attention, and respond appropriately in school and at home, he is probably an energetic individual. While the core symptoms that define ADHD can include hyperactivity, along with impulsivity and inattention, not all kids (or adults) with ADHD will have these symptoms in the same way or to the same degree. You will certainly see changes in the way the symptoms manifest or present as an individual moves through various stages of life.
For a child with ADHD, there is much more involved than simply being active and full of energy. In case you suspect something about your child’s development, it might be a good idea to check with your pediatrician to rule out ADHD.
