AAPs were introduced to child and adolescent psychiatry in the belief that they were better tolerated, especially with regard to a lower risk of extrapyramidal side effects.6 This appeared to be true; however, other side effects soon became apparent. Among children and adolescents, weight gain, or an increase in body mass index, emerges as one of the most significant side effects of AAPs, with an ensuing risk of type 2 diabetes, cardiovascular morbidity, and metabolic syndrome.
