BACKGROUND: Advocacy has been described by parents of children with autism as an important coping strategy, enabling them to move forward by redirecting emotions into actions. A key factor in the development of collaborative and constructive partnerships between service providers and parents is having an understanding of how parents engage in advocacy and the support needed to do so. This meta-synthesis was undertaken to consolidate in-depth qualitative data from parents’ perspectives of the process that they use to advocate for their children with autism. METHODS: A qualitative meta-synthesis was conducted, whereby 15 databases were systematically searched. Thirty-one studies were identified and appraised using an adapted version of the Critical Appraisal Skills Programme tool. Data were synthesized into themes through the steps of review, meta-aggregation, integration, and interpretation. RESULTS: The voices of 1,662 parents are presented describing the process of advocacy in the stages of seeking a diagnosis, seeking self-education, and taking action. Taking action includes 2 subthemes: seeking, access, and use of support services and community engagement and educating others. CONCLUSIONS: Results highlight the significant impact that positive experiences with first-line professionals have during the diagnosis process and how these experiences lay the foundation for all future relationships with other service providers. Important implications arise from this meta-synthesis for service providers in supporting parents’ advocacy and hence building constructive relationships with families with a child with autism.

Importance: Autism spectrum disorders (ASD) are characterized by impairments in social interaction, communication, and repetitive or restrictive behavior. Although multiple physiologic and biochemical studies have reported defects in mitochondrial oxidative phosphorylation in patients with ASD, the role of mitochondrial DNA (mtDNA) variation has remained relatively unexplored. Objective: To assess what impact mitochondrial lineages encompassing ancient mtDNA functional polymorphisms, termed haplogroups, have on ASD risk. Design, Setting, and Participants: In this cohort study, individuals with autism and their families were studied using the Autism Genetic Resource Exchange cohort genome-wide association studies data previously generated at the Children’s Hospital of Philadelphia. From October 2010 to January 2017, we analyzed the data and used the mtDNA single-nucleotide polymorphisms interrogated by the Illumina HumanHap 550 chip to determine the mtDNA haplogroups of the individuals. Taking into account the familial structure of the Autism Genetic Resource Exchange data, we then determined whether the mtDNA haplogroups correlate with ASD risk. Main Outcomes and Measures: Odds ratios of mitochondrial haplogroup as predictors of ASD risk. Results: Of 1624 patients with autism included in this study, 1299 were boys (80%) and 325 were girls (20%). Families in the Autism Genetic Resource Exchange collection (933 families, encompassing 4041 individuals: 1624 patients with ASD and 2417 healthy parents and siblings) had been previously recruited in the United States with no restrictions on age, sex, race/ethnicity, or socioeconomic status. Relative to the most common European haplogroup HHV, European haplogroups I, J, K, O-X, T, and U were associated with increased risk of ASD, as were Asian and Native American haplogroups A and M, with odds ratios ranging from 1.55 (95% CI, 1.16-2.06) to 2.18 (95% CI, 1.59-3) (adjusted P < .04). Hence, mtDNA haplogroup variation is an important risk factor for ASD. Conclusions and Relevance: Because haplogroups I, J, K, O-X, T, and U encompass 55% of the European population, mtDNA lineages must make a significant contribution to overall ASD risk.

Weak central coherence (processing details over gist), poor oral language abilities, poor suppression, semantic interference, and poor comprehension monitoring have all been implicated to affect reading comprehension in individuals with autism spectrum disorder (ASD). This study viewed the contributions of different supporting skills as a collective set of skills necessary for context integration-a multi-component view-to examine individual differences in reading comprehension in school-age children (8-14 years) with ASD (n = 23) and typically developing control peers (n = 23). Participants completed a written ambiguous sentence comprehension task in which participants had to integrate context to determine the correct homonym meaning via picture selection. Both comprehension products (i.e., offline representations after reading) and processes (i.e., online processing during reading) were evaluated. Results indicated that children with ASD, similar to their TD peers, integrated the context to access the correct homonym meanings while reading. However, after reading the sentences, when participants were asked to select the meanings, both groups experienced semantic interference between the two meanings. This semantic interference hindered the children with ASD’s sentence representation to a greater degree than their peers. Individual differences in age/development, word recognition, vocabulary breadth (i.e., number of words in the lexicon), and vocabulary depth (i.e., knowledge of the homonym meanings) contributed to sentence comprehension in both children with ASD and their peers. Together, this evidence supports a multi-component view, and that helping children with ASD develop vocabulary depth may have cascading effects on their reading comprehension. Autism Res 2017. (c) 2017 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Like their peers, children with ASD were able to integrate context, or link words while reading sentences with ambiguous words (words with two meanings). After reading the sentences, both groups found it hard to pick the correct meaning of the ambiguous sentence and this decision was more difficult for the participants with ASD. Older children, children with better word reading abilities, and children with higher vocabularies were better at understanding ambiguous sentences. Helping children with ASD to develop richer vocabularies could be important for improving their reading comprehension.

BACKGROUND: Adolescents with attention-deficit/hyperactive disorder (ADHD) or autism spectrum disorder (ASD) are at high risk of anxiety and depression. This is important to identify in the clinical assessment to understand its impact. AIMS: The aim of this study is to investigate the correlation between parent- and self-reports of anxiety and depression in adolescents with ADHD or ASD, as well as the correlation with adaptive functioning and performance on an attention test. METHOD: A total of 65 adolescents with an ADHD diagnosis (n = 24) or an ASD diagnosis (n = 41) filled out Beck Youth Inventories of Emotional and Social Impairment (BYI) to assess depression and anxiety and completed a Continuous Performance Test (QbTest) measuring ADHD symptoms. Parents of the participants completed the internalizing domain in the Five to Fifteen questionnaire (FTF), measuring symptoms of anxiety and depression, and the Vineland Adaptive Behavior Scales (VABS) about the adolescent’s adaptive functioning. RESULTS: Approximately a third of the study group self-reported substantial internalizing mental symptoms not always recognized by parents, and not always obvious in adaptive function or performance at ADHD test. Correlations between BYI and FTF were low. The BYI depression inventory correlated negatively with VABS and positively with activity level in a subgroup medicated for ADHD. There was a stronger correlation between girls BYI and FTF results as compared with boys. CONCLUSIONS: The results highlight the need for identification of anxiety and depression, using both self- and parent report. Present anxiety and depression symptoms do not seem to affect the clinical assessment of ASD and ADHD.

OBJECTIVE: To determine whether there is an association between parent and sibling obesity status and obesity status in children with autism spectrum disorder (ASD). METHODS: We examined predictors of obesity in children with ASD with body mass index data for the proband, 1 sibling, and 2 parents using data from the multisite Simons Simplex Collection. RESULTS: In a stepwise logistic regression model, proband obesity status was associated with obesity status of the sibling (odds ratio [OR] 2.66; 95% confidence interval [CI], 1.92-3.70), mother (OR 2.10; 95% CI, 1.59-2.77), and father (OR 1.51; 95% CI, 1.15-1.98). Proband obesity was also related to somatic complaints (OR 1.60; 95% CI, 1.006-2.53), mood stabilizers (OR 1.80; 95% CI, 1.19-2.72), internalizing problems (OR 1.60; 95% CI, 1.14-2.30), age (OR 1.01; 95% CI, 1.00-1.01), and some adaptive functioning domains (OR 0.987; 95% CI, 0.977-0.997). Race, ethnicity, income, sex, and maternal education were not significant predictors. CONCLUSION: Familial factors were generally the strongest predictors of obesity rather than medication use, demographics, or psychological characteristics. Results support a family-centered approach to treatment of obesity in children with ASD.

BACKGROUND: Two experiments investigated the contribution of conflict inhibition to pragmatic deficits in children with autism spectrum disorder (ASD). Typical adults’ tendency to reuse interlocutors’ referential choices (lexical alignment) implicates communicative perspective-taking, which is regulated by conflict inhibition. We examined whether children with ASD spontaneously lexically aligned, and whether conflict inhibition mediated alignment. METHODS: Children with ASD and chronological- and verbal-age-matched typically developing controls played a picture-naming game. We manipulated whether the experimenter used a preferred or dispreferred name for each picture, and examined whether children subsequently used the same name. RESULTS: Children with ASD spontaneously lexically aligned, to the same extent as typically developing controls. Alignment was unrelated to conflict inhibition in both groups. CONCLUSIONS: Children with ASD’s referential communication is robust to impairments in conflict inhibition under some circumstances. Their pragmatic deficits may be mitigated in a highly structured interaction.

Accuracy for reading comprehension and inferencing tasks has previously been reported as reduced for individuals with autism spectrum disorder (ASD), relative to typically developing (TD) controls. In this study, we used an eye movements and reading paradigm to examine whether this difference in performance accuracy is underpinned by differences in the inferential work required to compute a co-referential link. Participants read two sentences that contained a category noun (e.g., bird) that was preceded by and co-referred to an exemplar that was either typical (e.g., pigeon) or atypical (e.g., penguin). Both TD and ASD participants showed an effect of typicality for gaze durations upon the category noun, with longer times being observed when the exemplar was atypical, in comparison to typical. No group differences or interactions were detected for target processing, and verbal language proficiency was found to predict general reading and inferential skill. The only difference between groups was that individuals with ASD engaged in more re-reading than TD participants. These data suggest that readers with ASD do not differ in the efficiency with which they compute anaphoric links on-line during reading. Autism Res 2017. (c) 2017 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Individuals with autism spectrum disorder (ASD) have previously been reported to have difficulties with reading comprehension. This study examined whether a difference in the speed with which individuals with ASD form connections between words (co-reference processing) may contribute to comprehension difficulties. No evidence was found to suggest that ASD readers differ to typically developing readers in the speed of co-reference processing. Therefore, this data would suggest that differences in co-reference processing are unlikely to account for reading comprehension difficulties in ASD.

Although many studies have reported domain-general impaired duration perception for speech and nonspeech sounds in children with autism, it remained unclear whether this phenomenon is universally applicable regardless of language background. In some languages such as Finnish and Japanese, vowel duration serves a phonemic role that can signify semantic distinction, and in others (e.g., Mandarin Chinese), vowel duration does not carry this phonemic function. The present event-related potential study investigated neural sensitivity to duration contrasts in speech and nonspeech contexts in Mandarin-speaking children with autism and a control group of age-matched typically developing (TD) children. A passive oddball paradigm was adopted to elicit the mismatch negativity (MMN) and involuntary orienting response (P3a) for change detection. A pure tone condition and a vowel condition were used. The MMN results showed that the autism group had diminished response amplitudes and delayed latency in the pure tone condition compared to the TD group, whereas no group difference was found in the vowel condition. The P3a results showed no significant between-group MMN difference in the pure tone condition. In the vowel condition, the autism group had smaller P3a than the TD group. Together, the distinct patterns of discrimination and orienting responses for duration contrasts in pure tones and vowels are consistent with the « allophonic perception » theory for autism, which may reflect a compromised perceptual weighting system for speech learning.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that is behaviorally defined by social and communication impairments and restricted interests and repetitive behaviors. There is currently no biomarkers that can help in the diagnosis. Several studies suggest that mitochondrial dysfunction is commonly involved in ASD pathophysiology, but standard mitochondrial biomarkers are thought to be very variable. In the present study we examine a wide variety of plasma biomarkers of mitochondrial metabolism and the related abnormalities of oxidative stress and apoptosis in 41 ASD patients assessed for ASD severity using the Childhood Autism Rating Scales and 41 non-related age and sex matched healthy controls. Our findings confirm previous studies indicating abnormal mitochondrial and related biomarkers in children with ASD including pyruvate, creatine kinase, Complex 1, Glutathione S-Transferase, glutathione and Caspase 7. As a novel finding, we report that lactate dehydrogenase is abnormal in children with ASD. We also identified that only the most severe children demonstrated abnormalities in Complex 1 activity and Glutathione S-Transferase. Additionally, we find that several biomarkers could be candidates for differentiating children with ASD and typically developing children, including Caspase 7, gluthatione and Glutathione S-Transferase by themselves and lactate dehydrogenase and Complex I when added to other biomarkers in combination. Caspase 7 was the most discriminating biomarker between ASD patients and healthy controls suggesting its potential use as diagnostic marker for the early recognition of ASD pathophysiology. This study confirms that several mitochondrial biomarkers are abnormal in children with ASD and suggest that certain mitochondrial biomarkers can differentiate between ASD and typically developing children, making them possibly useful as a tool to diagnosis ASD and identify ASD subgroups.

BACKGROUND: Little research exists on suspension of students with autism or intellectual disabilities. We examined suspension rates of students with autism or intellectual disability in Maryland from 2004 to 2015 to understand whether race and disability status predicted the odds of being suspended. METHOD: We used school enrollment data and school suspension data in Maryland for analysis. Descriptive statistics by race and disability category were calculated. Logistic regression was used to examine differences in odds of suspension by race and by disability (ID and autism) each year. RESULTS: Suspension rates in Maryland decreased overall from 2004 to 2015, but African American students with intellectual disability or no disability were significantly more likely to be suspended. White students with autism and White students with intellectual disability had significantly higher odds of suspension than White students without a disability. CONCLUSIONS: Overall risk for suspension in Maryland decreased over time. African American students with autism or intellectual disability, as well as white students with autism or intellectual disability, experienced significantly higher odds of suspension when compared to their White students without a disability. This relatively unexplored issue commands attention from researchers and policymakers alike.

Autism spectrum disorder (ASD) represents a set of complex neurodevelopmental disorders with large degrees of heritability and heterogeneity. We sequenced 136 microcephaly or macrocephaly (Mic-Mac)-related genes and 158 possible ASD-risk genes in 536 Chinese ASD probands and detected 22 damaging de novo mutations (DNMs) in 20 genes, including CHD8 and SCN2A, with recurrent events. Nine of the 20 genes were previously reported to harbor DNMs in ASD patients from other populations, while 11 of them were first identified in present study. We combined genetic variations of the 294 sequenced genes from publicly available whole-exome or whole-genome sequencing studies (4167 probands plus 1786 controls) with our Chinese population (536 cases plus 1457 controls) to optimize the power of candidate-gene prioritization. As a result, we prioritized 67 ASD-candidate genes that exhibited significantly higher probabilities of haploinsufficiency and genic intolerance, and significantly interacted and co-expressed with each another, as well as other known ASD-risk genes. Probands with DNMs or rare inherited mutations in the 67 candidate genes exhibited significantly lower intelligence quotients, supporting their strong functional impact. In addition, we prioritized 39 ASD-related Mic-Mac-risk genes, and showed their interaction and co-expression in a functional network that converged on chromatin remodeling, synapse transmission and cell cycle progression. Genes within the three functional subnetworks exhibited distinct and recognizable spatiotemporal-expression patterns in human brains and laminar-expression profiles in the developing neocortex, highlighting their important roles in brain development. Our results indicate some of Mic-Mac-risk genes are involved in ASD.

OBJECTIVE: Antipsychotic use is controversial in the management of adults with intellectual and developmental disabilities (IDD) because of inconclusive evidence for efficacy in the absence of a comorbid psychiatric condition, and substantial concerns about adverse effects. We aimed to characterize antipsychotic use among Ontario adults with IDD and compare profiles of those with and without a documented psychiatric diagnosis. METHOD: This population-based study included 51,881 adults with IDD under 65 y as of April 2010 receiving provincial drug benefits in Ontario who were followed until March 2016 to identify those dispensed at least one antipsychotic medication. Profiles of those with and without a psychiatric diagnosis were compared. RESULTS: Overall, 39.2% of adults ( n = 20,316) were dispensed an antipsychotic medication, which increased to 56.4% in a subcohort residing in group homes. Almost one-third (28.91%) of people prescribed an antipsychotic medication did not have a documented psychiatric diagnosis. Those without a psychiatric diagnosis differed considerably from those with a diagnosis. In particular, those without a psychiatric diagnosis were older, less likely to have used antidepressants or benzodiazepines in the year before, and less likely to have used ambulatory and acute care. CONCLUSIONS: Antipsychotic use in IDD is common, and occurs frequently without a psychiatric diagnosis. Attention toward how antipsychotics are prescribed and monitored for people with IDD in Canada is warranted to ensure appropriate prescribing.

BACKGROUND: The efficacy of mindfulness-based interventions (MBIs) for stress and psychological distress in professional caregivers supporting individuals with intellectual or developmental disabilities (IDDs) is reviewed. METHODS: Eight studies met inclusion criteria and were systematically reviewed, including RCTs and single-group designs. RESULTS: As per Reichow, Volkmar, and Cicchetti (Journal of Autism and Developmental Disorders, 38, 2008), three studies were classified as « adequate quality » and five were classified as « weak. » There were inconsistent findings in relation to stress, with significant reductions or increases reported by caregivers following MBIs. MBIs consistently improved caregivers’ ratings of distress. Process outcomes suggested increased mindful awareness, increased cognitive defusion and reduced thought suppression. Treatment effects were maintained or continued to grow at follow-up. CONCLUSIONS: Caregivers of individuals with IDDs face multiple challenges on a daily basis. This review supports, at least, short-term benefits for MBIs in the management of stress and distress in caregivers of individuals with IDDs.

Elevated prenatal testosterone exposure has been associated with Autism Spectrum Disorder (ASD) and facial masculinity. By employing three-dimensional (3D) photogrammetry, the current study investigated whether prepubescent boys and girls with ASD present increased facial masculinity compared to typically-developing controls. There were two phases to this research. 3D facial images were obtained from a normative sample of 48 boys and 53 girls (3.01-12.44 years old) to determine typical facial masculinity/femininity. The sexually dimorphic features were used to create a continuous ‘gender score’, indexing degree of facial masculinity. Gender scores based on 3D facial images were then compared for 54 autistic and 54 control boys (3.01-12.52 years old), and also for 20 autistic and 60 control girls (4.24-11.78 years). For each sex, increased facial masculinity was observed in the ASD group relative to control group. Further analyses revealed that increased facial masculinity in the ASD group correlated with more social-communication difficulties based on the Social Affect score derived from the Autism Diagnostic Observation Scale-Generic (ADOS-G). There was no association between facial masculinity and the derived Restricted and Repetitive Behaviours score. This is the first study demonstrating facial hypermasculinisation in ASD and its relationship to social-communication difficulties in prepubescent children.

Mutations in the kinesin family member 1A (KIF1A) gene have been associated with a wide range of phenotypes including recessive mutations causing hereditary sensory neuropathy and hereditary spastic paraplegia and de novo dominant mutations causing a more complex neurological disorder affecting both the central and peripheral nervous system. We identified by exome sequencing a de novo dominant missense variant, (c.38G>A, p.R13H), within an ATP binding site of the kinesin motor domain in a patient manifesting a complex phenotype characterized by autism spectrum disorder, spastic paraplegia and axonal neuropathy. The presence of autism spectrum disorder distinguishes this case from previously reported patients with de novo dominant mutations in KIF1A.

Autism spectrum disorder (ASD) is associated with two core symptoms (social communication deficits and stereotyped repetitive behaviors) in addition to a number of comorbidities. There are no FDA-approved drugs for the core symptoms and the changes that underlie these behaviors are not fully understood. One hypothesis is an imbalance of the excitation (E)/inhibition (I) ratio with excessive E and diminished I occurring in specific neuronal circuits. Data suggests that both gamma-aminobutyric acidA (GABAA) and alpha7 nicotinic acetylcholine receptors (nAChRs) significantly impact E/I. BTBR T+tf/J (BTBR) mice are a model that display an autism-like phenotype with impaired social interaction and stereotyped behavior. A beta2/3-subunit containing GABAA receptor (GABAAR) subtype selective positive allosteric modulator (PAM), 2-261, and an alpha7 nAChR subtype selective PAM, AVL-3288, were tested in social approach and repetitive self-grooming paradigms. 2-261 was active in the social approach but not the self-grooming paradigm, whereas AVL-3288 was active in both. Neither compound impaired locomotor activity. Modulating alpha7 nAChRs alone may be sufficient to correct these behavioral and cognitive deficits. GABAergic and nicotinic compounds are already in various stages of clinical testing for treatment of the core symptoms and comorbidities associated with ASD. Our findings and those of others suggest that compounds that have selective activities at GABAAR subtypes and the alpha7 nAChR may address not only the core symptoms, but many of the associated comorbidities as well and warrant further investigation in other models of ASD.
