    A retrospective chart study of patients on open-label aripiprazole treatment was conducted in the Netherlands to add to the knowledge of aripiprazole in children and young adults with mild and borderline intellectual disabilities (IDs). Fifty-three youths, mean age 14.7 +/- 3.4 years and mean IQ 64.5 +/- 13.8, were included. Treatment responders were defined as "much improved" or "very much improved" based on the Clinical Global Impression -Improvement scale. For 83% of the patients, disruptive behavior was the main target symptom. The overall response rate was 30% after 1-4 weeks and 69% after 5-8 weeks. The 5-8 weeks responders showed a response rate of 64% at 22-26 weeks. Mild adverse events were observed in 53% of the patients of which fatigue and weight gain were the most common. Seven patients (13.2%) discontinued because of adverse events. In 53 children and young adults with mild and borderline IDs, aripiprazole was effective in both the short and the long term. No serious adverse events were observed

    Chronic Stressors and Adolescents' Externalizing Problems:Genetic Moderation by Dopamine Receptor D4. The TRAILS Study

    The existing literature does not provide consistent evidence that carriers of the Dopamine D4 Receptor 7-repeat allele are more sensitive to adverse environmental influences, resulting in enhanced externalizing problems, compared to noncarriers. One explanation is that the adverse influences examined in prior studies were not severe, chronic, or distressing enough to reveal individual differences in sensitivity reflected by DRD4-7R. This study examined whether the 7-repeat allele moderated the association between chronic stressors capturing multiple stressful aspects of individuals' lives and externalizing problems in adolescence. We expected that chronic stressor levels would be associated with externalizing levels only in 7-repeat carriers. Using Linear Mixed Models, we analyzed data from 1621 Dutch adolescents (52.2% boys), obtained in three measurement waves (mean age approximately 11, 13.5, and 16 years) from the TRacking Adolescents' Individual Lives Survey (TRAILS) population-based birth cohort and the parallel clinic-referred cohort. Across informants, we found that higher levels of chronic stressors were related to higher externalizing levels in 7-repeat carriers but not in noncarriers, as hypothesized. Although previous studies on the 7-repeat allele as a moderator of environmental influences on adolescents' externalizing problems have not convincingly demonstrated individual differences in sensitivity to adverse environmental influences, our findings suggest that adolescent carriers of the Dopamine D4 Receptor 7-repeat allele are more sensitive to chronic, multi-context stressors than noncarriers
