Brief Report: Challenging Behaviors in Toddlers and Preschoolers with Angelman, Prader-Willi, and Williams Syndromes.
We examined challenging behaviors in 86 toddlers and preschoolers across three NGS [Angelman syndrome (AS), Prader-Willi syndrome (PWS), and Williams syndrome (WS)] and 43 low-risk controls (LRC), using the Child Behavior Checklist for Ages 1½-5. Challenging behavior profiles differed across NGS, with generally elevated behaviors in AS and WS, but not PWS, relative to LRC. Withdrawn and autism spectrum symptoms were particularly elevated in AS. Although several profiles were similar to those previously reported in older children and adults, we also observed inconsistencies that suggest non-linear developmental patterns of challenging behaviors. These findings underscore the importance of characterizing early challenging behaviors to inform atypical phenotypic development and targeted intervention.

ConclusionsAll patients with severe autism had SPAs. However, they did not correlate with FDG-PET findings.
Stephanie Nimmo, 51, from South-West London, is aware that, by speaking out in favour of vaccinations, she will be hit by a furious backlash from the anti-vax community.
One in every 59 children born in the United States will develop autism. Yet much of the biology behind the disorder remains unknown. That may soon change thanks to a $20 million gift from Wall Street investment banker K. Lisa Yang and her husband, Broadcom CEO Hock E. Tan, to Harvard University, which will bring together scientists and researchers in a new Center for Autism Research to better understand the underpinnings of the disease. “The crux of our center is to have input from people in…

AbstractIn humans, variations in the polysialic acid ‐producing enzyme ST8SIA2 and disturbances in the cortical inhibitory system are associated with neurodevelopmental psychiatric disorderssuch as schizophrenia and autism. In mice, the ST8SIA2‐dependent formation of polysialic acid during embryonic development is crucial for the establishment of interneuron populations of the medial prefrontal cortex (mPFC). However, the spatial pattern and the neurodevelopmental mechanisms of interneuron changes caused by loss of ST8SIA2 functionhave not been fully characterized. Here, we use immunohistochemical analysis to demonstra...
CONCLUSIONS: Our findings suggest the necessity of CMA as a routine diagnostic test for unexplained DD, MR, and ASD in Korea. PMID: 26206688 [PubMed - in process]
