This study compared the clinical efficacy of a dopaminergic antagonist (amisulpride) and a dopaminergic agonist (bromocriptine) with 9 children (ages 4-13) with autism and probable severe mental retardation. The amisulpride acted preferentially on specific autism symptoms and the bromocriptine on motor hyperactivity and attention symptoms.…

This paper on the behavioral manifestations of child sexual abuse first reviews previous research concerning child variables, parent/family variables, sexual abuse in combination with other maltreatment, and physiological outcomes. Criteria for future research are offered and specific research needs in the areas of developmental progression,…
