Not all kids with ADHD are alike
Each child with ADHD has a different combination of symptoms, but these symptoms fit into one of three different subtypes. The first is the predominantly inattentive type, which was formerly called ADD. The second is the predominantly hyperactive/impulsive type. The third is the combined type, exhibiting all three of these areas. This is the most common type of ADHD.
Children with the predominantly inattentive subtype of ADHD are less likely to be disruptive in school, have outbursts at home, be very challenging for parents to manage, or have difficulties getting along with other children. They may sit quietly, but they are not paying attention to what they are doing. A youngster may simply appear to be a daydreamer, absent-minded, or bored. Therefore, she may be overlooked, and parents and teachers may not notice that she has ADHD until she falls seriously behind in school.
