Autistic traits,ADHD symptoms,neurological soft signs and regional cerebral blood flow in adults with autism spectrum disorders

The resting regional cerebral blood flow (rCBF) patterns related to co-occurring symptoms such as inattention, hyperactivity, neurological soft signs and motor problems have not yet been disclosed in autism spectrum disorders (ASD). In this study thirteen adults with ASD and ten matched neurotypical controls underwent PET. The scores of rating scales for autistic traits, attention deficit hyperactivity disorder (ADHD) and neurological soft signs were included in a factorial analysis and correlated with rCBF. Factors corresponding to \u27\u27autistic/ADHD traits\u27\u27, \u27\u27sensory-motor integration\u27\u27 and \u27\u27Intelligence/Motor sequencing\u27\u27 were identified. In the ASD group, positive correlations with CBF were found for \u27\u27autistic/ADHD traits\u27\u27 in caudate bilaterally and the inferior parietal lobule, for \u27\u27sensory-motor integration\u27\u27 in parieto-occipital cortex and for \u27\u27Intelligence/Motor sequencing\u27\u27 in the right temporal cortex. Notably, CBF in the left thalamus correlated negatively with all three factors. Autistic traits and ADHD symptoms were associated with shared neural substrates. The correlation between \u27\u27autistic/ADHD traits\u27\u27 and rCBF in the caudate is possibly associated with the executive impairments and ritualistic/stereotyped behaviors apparent in ASD. Furthermore, sensory-motor deficits were correlated with rCBF in the occipital visual cortex, involved in atypical visual perception in ASD. Various behavioral and neurological symptoms are suggested to converge into the ASD phenotype

National Career Development Strategy (NCDS) Research Project - Element 2: Qualitative Research

Urbis was commissioned by the Australian Government Department of Education, Employment and Workplace Relations (DEEWR) to identify and analyse the career development needs and wants of young people (5-24 years), their parents, teachers and communities. The purpose of this research is to inform the creation of a National Career Development Strategy (NCDS)
