Background: Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder, the etiology of which has not been clearly determined yet. There is increasing evidence that synaptic and dendritic changes are involved in the etiology of ASD. The aim of this study is to determine whether serum Thrombospondin-1 and Thrombospondin-2 differ between ASD…

In clinical trials, individuals taking concomitant psychotropic medications often are excluded to maintain homogeneity and prevent contamination of clinical endpoints. However, this choice may compromise the representativeness of the sample. In…

Fragile X syndrome (FXS) is characterized by variable neurobehavioral abnormalities, which leads to difficulties in developing and evaluating treatments and in determining accurate prognosis. We employed a pediatric cross-sectional sample (1,072 males, 338 females) from FORWARD, a clinic-based natural history study, to identify behavioral subtypes…

Sabine S. Chebli; Valérie Martin; Marc J. Lanovaz – Review Journal of Autism and Developmental Disorders, 2016
Although many researchers have examined the prevalence of stereotypy in individuals with developmental disabilities, the results of previous studies have not been aggregated and analyzed methodically. Thus, we conducted a systematic review of studies reporting the prevalence of stereotypy in individuals with developmental disabilities. Our results…
