Although children with autism spectrum disorder (ASD) show atypical sensory processing, evidence for impaired integration of multisensory information has been mixed. In this study, we took a Bayesian model-based approach to assess within-modality integration of congruent and incongruent texture and disparity cues to judge slant in typical and autistic adolescents. Human adults optimally combine...

Neuroimaging studies of neuropsychiatric behavior biomarkers across spectrum disorders are typically based on diagnosis, thus failing to account for the heterogeneity of multi-dimensional spectrum disorders such as autism (ASD). Control group trait phenotypes are also seldom reported. Proton magnetic resonance spectroscopy ((1)H-MRS) measures the abundance of neurochemicals such as neurotransmi...

Sensory dysfunctions may underlie key characteristics in children with Autism Spectrum Disorders (ASD). The current study aimed to investigate auditory change detection in children with ASD in order to determine event-related potentials to meaningless and meaningful speech stimuli. 11 high functioning boys with a diagnosis of autism spectrum disorders (mean age = 13.0; SD = 1.08) and 11 typical...

BACKGROUND Atypical reactions to sensory stimuli show heritability in the general population and are a known risk factor for affective disorders. As sensory problems are highly prevalent in individuals with ASD and their siblings, and the occurrence of affective disorders is elevated in parents of children with ASD, investigating sensory symptoms in parents is important both from clinical and t...

Attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are associated with varied executive function (EF) difficulties. Callous-unemotional (CU) traits, a proposed antecedent of adult psychopathy, are often associated with intact or enhanced EF. Here we test whether CU traits may therefore modulate EF in ASD and ADHD, in which EF is typically impaired. We collected C...

Individuals with autism spectrum disorder (ASD), including those who otherwise require less support, face severe difficulties in everyday social interactions. Research in this area has primarily focused on identifying the cognitive and neurological differences that contribute to these social impairments, but social interaction by definition involves more than one person and social difficulties ...

utism-spectrum disorder (ASD) is a developmental Abehavioral disorder often accompanied and aggravated by a range of gastrointestinal and cognitive dysfunction. The concern for ASD reflects its increasing incidence and the disproportionate burden of this and other cognitive disorders on those affected and the family and community around them. Is there a role for us to help from the distant fiel...

Literature on the co-occurrence between Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD) is strongly biased by a focus on childhood age. A review of the adolescent and adult literature was made on core and related symptoms of ADHD and ASD. In addition, an empirical approach was used including 17,173 ASD-ADHD symptom ratings from participants aged 0 to 84 years....

Chronic pressure overload leads to hypertrophy, depressed mechanical function, and reduced myosin ATPase activity. However, it is not known whether the lowered myosin ATPase activity results from the hypertrophic process per se or whether the elevated afterload is required for the depressed myosin ATPase activity. Further, a causal relationship between lowered myosin ATPase and weakened mechani...

STUDY DESIGN Prospective, multicenter, international observational study. OBJECTIVE To evaluate motor neurologic outcomes in patients undergoing surgery for complex adult spinal deformity (ASD). SUMMARY OF BACKGROUND DATA The neurologic outcomes after surgical correction for ASD have been reported with significant variability and have not been measured as a primary endpoint in any prospecti...
