If your child is exhibiting qualities of selective attention, impulsivity, distractibility and in some children hyperactivity, then your child might have A.D.D. In some cases A.D.D. can go untreated and often children that do not exhibit all traits can be considered in the realm of normal although there is an issue. It is important to not think of A.D.D. as a disorder, but that your child is just different in his or her own learning style.
