Practical applications of brief screening questionnaires for autism spectrum disorder in a psychiatry outpatient setting.

ABSTRACT:

Objectives

This study was designed to examine the diagnostic performance of the social and communication disorders checklist (SCDC) and strength and difficulties questionnaire (SDQ) to detect autism spectrum conditions (ASC), along with the social responsiveness scale-second edition (SRS-2) as reference, in a psychiatry outpatient setting.

Methods

We translated the SCDC into Japanese since its Japanese version was unavailable. We examined its test-retest reliability as well as the internal consistency reliability and diagnostic performance of the three questionnaires among 41 Japanese psychiatric outpatients, using the best-estimate diagnosis of ASC based on the diagnostic interview for social and communication disorders, as a gold standard.

Results

The test-retest reliability was high for the SCDC. Although the internal consistency reliability was high for the SCDC and SRS-2, that was low for the prosocial and peer problem subscales of the SDQ. The performance of the SCDC, SDQ, and SRS-2 to detect ASC was moderate: the area under the ROC curve of 0.78, 0.78, and 0.84, respectively.

Conclusions

Although questionnaires to detect ASC, including the three examined, generally have only moderate performance in this setting, these can be successfully applied to high-risk populations such as psychiatry outpatients, when multi-level rather than dichotomous likelihood ratios are used.

Practical Management: Brief Physical Examination for Sport-Related Concussion in the Outpatient Setting.

Project description:This article presents a brief, focused physical examination [PE, the Buffalo Concussion Physical Examination (BCPE)] for sport-related concussion (SRC) to be considered for use in the outpatient setting by sports medicine physicians, pediatricians, and primary-care physicians. This companion paper describes how to perform the PE, which was derived in a separate study presented in this journal. It is envisioned for use at the initial and follow-up outpatient visits both for acute concussions and in patients with prolonged symptoms. A pertinent PE, combined with other assessments, can help identify specific treatment targets in those with persistent symptoms after SRC. The BCPE includes orthostatic vital signs and examinations of the cranial nerves, oculomotor/ophthalmologic, cervical, and vestibular systems. Supplementary tests, including testing for exercise tolerance and neurocognitive function, may be performed if indicated. It is recommended that a PE be performed at the initial visit and every 1 to 2 weeks after SRC. On return of symptoms, cognition, and the PE to baseline, as well as normalization of any supplementary tests, patients can begin a return to play program.

Comorbid autism spectrum disorder and anxiety disorders: a brief review.

Project description:Appearing in 40% of the cases of autism spectrum disorder (ASD), comorbid anxiety presents unique challenges for practitioners by amplifying problem behaviors such as social skills deficits, resistance to change and repetitive behaviors. Furthermore, comorbid ASD/anxiety strains familial relationships and increases parental stress. Research indicates that the neurobiological interactions between anxiety and ASD require comprehensive assessment approaches, modified cognitive behavioral therapy and carefully managed pharmacological interventions. Meta-analyses indicate that cognitive behavioral therapy with exposure is an effective treatment option when adequately accounting for social, familial and cognitive variables. The purpose of this focused review is to update readers on the latest research advances in comorbid ASD and anxiety, including prevalence, assessment, psychosocial and pharmacological treatment.

Measuring treatment response in children with autism spectrum disorder: Applications of the Brief Observation of Social Communication Change to the Autism Diagnostic Observation Schedule.

Project description:This study aims to determine the validity and reliability of applying the coding strategy from the Brief Observation of Social Communication Change, a newly validated treatment outcome measure, to videotaped segments of the Autism Diagnostic Observation Schedule. Results indicate strong reliability and validity of the Brief Observation of Social Communication Change ratings using the Autism Diagnostic Observation Schedule segments in detecting changes in social communication over the course of treatment in young, minimally verbal children with autism spectrum disorder. Results also suggest that the Brief Observation of Social Communication Change, when applied to Autism Diagnostic Observation Schedule segments, may be more sensitive in detecting subtle changes in social communication compared to the Autism Diagnostic Observation Schedule Calibrated Severity Scores. These results may support the application of the Brief Observation of Social Communication Change to pre-existing datasets of Autism Diagnostic Observation Schedule videos to examine treatment responses.

Genetics of Autism Spectrum Disorder: Current Status and Possible Clinical Applications.

Project description:Autism spectrum disorder (ASD) is one of the most complex behavioral disorders with a strong genetic influence. The objectives of this article are to review the current status of genetic research in ASD, and to provide information regarding the potential candidate genes, mutations, and genetic loci possibly related to pathogenesis in ASD. Investigations on monogenic causes of ASD, candidate genes among common variants, rare de novo mutations, and copy number variations are reviewed. The current possible clinical applications of the genetic knowledge and their future possibilities are highlighted.

Rare genetic susceptibility variants assessment in autism spectrum disorder: detection rate and practical use.

Project description:Autism spectrum disorder (ASD) is a neurodevelopmental disorder with a strong genetic component whose knowledge evolves quickly. Next-generation sequencing is the only effective technology to deal with the high genetic heterogeneity of ASD in a clinical setting. However, rigorous criteria to classify rare genetic variants conferring ASD susceptibility are currently lacking. We have performed whole-exome sequencing to identify both nucleotide variants and copy number variants (CNVs) in 253 ASD patients, including 68 patients with intellectual disability (ID) and 90 diagnosed as Asperger syndrome. Using explicit criteria to classify both susceptibility genes and susceptibility variants we prioritized 217 genes belonging to the following categories: syndromic genes, genes with an excess of de novo protein truncating variants and genes targeted by rare CNVs. We obtained a susceptibility variant detection rate of 19.7% (95% CI: [15-25.2%]). The rate for CNVs was 7.1% (95% CI: [4.3-11%]) and 12.6% (95% CI: [8.8-17.4%]) for nucleotide variants. The highest rate (30.1%, 95% CI: [20.2-43.2%]) was obtained in the ASD + ID subgroup. A strong contributor for at risk nucleotide variants was the recently identified set of genes (n = 81) harboring an excess of de novo protein truncating variants. Since there is currently no evidence that the genes targeted here are necessary and sufficient to cause ASD, we recommend to avoid the term "causative of ASD" when delivering the information about a variant to a family and to use instead the term "genetic susceptibility factor contributing to ASD".

Autism spectrum disorder.

Project description:Autism spectrum disorder is a construct used to describe individuals with a specific combination of impairments in social communication and repetitive behaviours, highly restricted interests and/or sensory behaviours beginning early in life. The worldwide prevalence of autism is just under 1%, but estimates are higher in high-income countries. Although gross brain pathology is not characteristic of autism, subtle anatomical and functional differences have been observed in post-mortem, neuroimaging and electrophysiological studies. Initially, it was hoped that accurate measurement of behavioural phenotypes would lead to specific genetic subtypes, but genetic findings have mainly applied to heterogeneous groups that are not specific to autism. Psychosocial interventions in children can improve specific behaviours, such as joint attention, language and social engagement, that may affect further development and could reduce symptom severity. However, further research is necessary to identify the long-term needs of people with autism, and treatments and the mechanisms behind them that could result in improved independence and quality of life over time. Families are often the major source of support for people with autism throughout much of life and need to be considered, along with the perspectives of autistic individuals, in both research and practice.

Brief Report: Caregiver Confidence in Reporting Anxiety Symptoms in Children with Autism Spectrum Disorder.

Project description:Assessment of anxiety in children with autism spectrum disorder (ASD) most commonly includes parent questionnaires. However, due to the nature of the questions and verbal limitations often present in children with ASD, caregivers may have difficulty completing such measures. Caregivers of 144 children with ASD ages 6 to 12 completed the Child and Adolescent Symptom Inventory-4 ASD Anxiety Scale and rated their level of confidence in responding to each item. Results indicated that parents had a moderate to high level of confidence in rating their children's anxiety symptoms. Parent confidence was not influenced by their child's age, expressive language ability, or intellectual functioning, but was related to their child's anxiety symptom count and ASD severity.

Epigenome analysis of autism spectrum disorder samples

Project description:The aim of this study was to identify ASD vulnerability components, explore possible vulnerability subgroups, and evaluate environmental contribution to phenotypic variability. We performed PCA and cluster analysis using ASD risk factor data. We found that PC1 had a higher correlation with psychosocial stress (maternal stress, maternal education, and social class), and PC2 a higher correlation with biological factors (Psychiatric Family History and Gestational Complications). Clustering analysis of PCA scores using bootstrap approach showed two clusters. Comparing the methylome between clusters we found 11.879 DMPs (p<0.05), and their CpG sites were enriched in VMRs, most showing environmental and genetic influences. Hypermethylated probes presented higher rates in different regulatory regions associated with functional SNPs, indicating that the subgroups may have different affected regulatory regions and their liability to disease explained by common variations. Vulnerability score moderated by epigenetic clock was associated with Vineland Total score (p=0.0036, adjR2=0.31), suggesting risk factors with stress burden can influence phenotype.

RNA-seq of 36 individuals with autism spectrum disorder

Project description:To assess the clinical impact of splice-altering noncoding mutations in autism spectrum disorder (ASD), we used a deep learning framework (SpliceAI) to predict the splice-altering potential of de novo mutations in 3,953 individuals with ASD from the Simons Simplex Collection. To validate these predictions, we selected 36 individuals that harbored predicted de-novo cryptic splice mutations; each individual represented the only case of autism within their immediate family. We obtained peripheral blood-derived lymphoblastoid cell lines (LCLs) and performed high-depth mRNA sequencing (approximately 350 million 150 bp single-end reads per sample). We used OLego to align the reads against a reference created from hg19 by substituting de novo variants of each individual with the corresponding alternate allele.
