The objective of this study was to assess the tolerability and efficacy of pregnenolone in reducing irritability in adults with autism spectrum disorder (ASD). This was a pilot, open-label, 12-week trial that included twelve subjects with a mean age of 22.5 ± 5.8 years. Two participants dropped out of the study due to reasons unrelated to adverse effects. Pregnenolone yielded a statistically significant improvement in the primary measure, Aberrant Behavior Checklist (ABC)-Irritability [from 17.4 ± 7.4 at baseline to 11.2 ± 7.0 at 12 weeks (p = 0.028)]. Secondary measures were not statistically significant with the exception of ABC-lethargy (p = 0.046) and total Short Sensory Profile score (p = 0.009). No significant vital sign changes occurred during this study. Pregnenolone was not associated with any severe side effects. Single episodes of tiredness, diarrhea and depressive affect that could be related to pregnenolone were reported. Overall, pregnenolone was modestly effective and well-tolerated in individuals with ASD.

The aim of this study was to examine the relationship between emotion dysregulation and the core features of Autism Spectrum Disorder (ASD), which include social/communication deficits, restricted/repetitive behaviors, and sensory abnormalities. An 18-item Emotion Dysregulation Index was developed on the basis of expert ratings of the Child Behavior Checklist. Compared to typically developing controls, children and adolescents with ASD showed more emotion dysregulation and had significantly greater symptom severity on all scales. Within ASD participants, emotion dysregulation was related to all core features of the disorder, but the strongest association was with repetitive behaviors. These findings may facilitate the development of more effective therapeutic strategies targeting emotion dysregulation in order to optimize long-term outcomes for individuals with ASD.

To determine the genetic relationship between head circumference (HC) and Autism Spectrum Disorders (ASDs). Twin pairs with at least one twin with an ASD were assessed. HCs in affected and unaffected individuals were compared, as were HC correlations in monozygotic and dizygotic pairs. 404 subjects, ages 4-18, were included. 20% of males and 27% of females with an ASD had macrocephaly. Unaffected co-twins showed similar rates (16% of males and 22% of females). Statistical analysis revealed no significant difference in HCs between affected and unaffected twins. Twins with ASDs and unaffected co-twins have similar HCs and increased rates of macrocephaly. Correlations demonstrated partial inheritance of HCs. Thus, macrocephaly may represent an endophenotype in ASDs.

The authors examined U.S. war veterans' career concerns (e.g., interests, personality, barriers, career thoughts) to provide possible avenues for research-based and theory-driven intervention. The veterans who participated in the study were receiving mental health, substance abuse, and vocational services at a residential facility. Participants were found to have interests in all RIASEC (J. L. Holland, B. A. Fritzsche, & A. B. Powell, 1994; J. L. Holland & G. D. Gottfredson, 1994) interest areas, and negative career thinking was found to be related to a variety of negative indicators. Suggestions are provided for working with veterans using the Cognitive Information Processing approach to career decision making. (Contains 1 table.)

Maladaptive behavior is common in Autism Spectrum Disorder (ASD). However, the factors that give rise to maladaptive behavior in this context are not well understood. The present study examined the role of emotion experience and emotion regulation in maladaptive behavior in individuals with ASD and typically developing (TD) participants. Thirty-one individuals with ASD and 28 TD participants and their parents completed questionnaires assessing emotion experience, regulation, and maladaptive behavior. Compared to TD participants, individuals with ASD used cognitive reappraisal less frequently, which was associated with increased negative emotion experience, which in turn was related to greater levels of maladaptive behavior. By decreasing negative emotions, treatments targeting adaptive emotion regulation may therefore reduce maladaptive behaviors in individuals with ASD., Author(s): Andrea C. Samson[sup.1] , Antonio Y.
