ABSTRACT
As we have seen in the previous chapters, ADD is a complex disorder that affects individuals throughout their lives. Biochemical deficits and neurologic dysfunction (Chapter 1) are probably present from birth, resulting in the atypical infants described in Chapter 2. Attentional deficits and hyperactivity become manifest in the toddler, with evidence of developmentally inappropriate levels of functioning in attention and motor control (Chapter 3). Definitive diagnosis is made in most cases by elementary school, but this population continues to be heterogeneous, with multiple difficulties across various areas of functioning, including behavior, peer relationships, self-esteem, emotional control, and learning (Chapter 4).
