Minor Physical Anomalies (MPAs) are subtle abnormalities of the head, face, and limbs, without significant cosmetic or functional impact to the individual. They are assumed to represent external markers of developmental deviations during foetal life. MPAs have been suggested to indicate severity in mental illness and constitute external markers for atypical brain development. Higher frequencies of MPAs can be found in children with autism. The aims of the present study were to examine the prevalence and patterns of MPAs in adults with autism spectrum disorder (ASD) and to investigate whether MPAs are associated with symptom severity and overall functioning. Fifty adults with ASD and intelligence within the normal range and 53 healthy controls were examined with the Waldrop scale, an instrument for assessing MPAs. Face and feet were photographed enabling blinded assessment. Significant differences between the ASD and the control group were found on the MPA total scores, and also in the craniofacial region scores. Moreover, the shape of the ears was associated with autistic traits, in the ASD group. High MPA total scores were associated with poorer functioning. The findings suggest a link between MPAs, autistic traits, and level of functioning. Assessment of MPAs may assist in the diagnostic procedure of psychiatric disorders.

AbstractWhile many individuals with autism spectrum disorder (ASD) experience difficulties with language processing, non-linguistic semantic processing may be intact. We examined neural responses to an implicit semantic priming task by comparing N400 responses—an event-related potential related to semantic processing—in response to semantically related or unrelated pairs of words or pictures. Adults with ASD showed larger N400 responses than typically developing adults for pictures, but no group differences occurred for words. However, we also observed complex modulations of N400 amplitude by age and by level of autistic traits. These results offer important implications for how groups are delineated and compared in autism research.

Dental anxiety is associated with previous distressing dental experiences, such as lack of understanding of the dentist intentions, perceptions of uncontrollability and experiences of pain during dental treatment. People with autism spectrum disorder (ASD) are impaired in building flexible predictions and expectations, which is very much needed during a dental visit. The aims of the study were to investigate if people with ASD have more negative dental experiences and a higher level of dental anxiety compared to a matched control group. Forty-seven adults with ASD and of normal intellectual performance, and 69 age- and sex-matched typically developing controls completed questionnaires on previous dental experiences and dental anxiety, the Dental Anxiety Scale, and the Dental Beliefs Survey. The ASD group experienced pain during dental treatments more often than the controls and 22% had repeatedly experienced being forced to dental treatment they were not prepared for, compared to 3% of the controls. A higher level of dental anxiety was reported by the ASD group. Dental treatment and methods for supporting the communication with patients with ASD need to be developed, in order to reduce the negative dental experiences and dental anxiety in people with ASD.

AbstractBackgroundThe promise of precision medicine for autism spectrum disorder (ASD) hinges on developing neuroscience-informed individualized interventions. Taking an important step in this direction, we investigated neuroplasticity in response to an ecologically-valid, computer-based social-cognitive training (SCOTT).MethodsIn an active control group design, 48 adults with ASD were randomly assigned to a 3-month SCOTT or non-social computer training. Participants completed behavioral tasks, a functional and structural magnetic resonance imaging session before and after the training period.ResultsThe SCOTT group showed social-cognitive improvements on close and distant generalization tasks. The improvements scaled with reductions in functional activity and increases in cortical thickness in prefrontal regions.ConclusionIn sum, we provide evidence for the sensitivity of neuroscientific methods to reflect training-induced social-cognitive improvements in adults with ASD. These results encourage the use of neuroimaging data to describe and quantify treatment-related changes more broadly.

BackgroundChildren and adolescents with autism spectrum disorder (ASD) are a highly medicated group. Few studies have examined the neuropsychiatric profile and patterns of psychotropic medication use among adults with ASD.AimsTo describe and compare the neuropsychiatric profile and psychotropic medication use in a cohort of adults with ASD and non-autistic controls.MethodBaseline data from a survey-based, longitudinal study of adults with ASD in Australia. Participants were 188 adults with ASD and 115 controls aged 25–80 years.ResultsASD was associated with increased odds of psychotropic medication use even when controlling for the presence of any neurological or psychiatric disorder. There were no corresponding indications for 14.4% of psychotropic medications prescribed to adults with ASD.ConclusionsThis study found substantial psychotropic prescribing for adults with ASD. Patterns of psychotropic medication use may reflect prescribing for behavioural indications despite limited evidence to support this practice.Declaration of interestNone.

Vocal Pitch

We tested the ability to recognise speech-in-noise and its relation to the ability to discriminate vocal pitch in adults with high-functioning autism spectrum disorder (ASD) and typically developed adults (matched pairwise on age, sex, and IQ). Typically developed individuals understood speech in higher noise levels as compared to the ASD group. Within the control group but not within the ASD group, better speech-in-noise recognition abilities were significantly correlated with better vocal pitch discrimination abilities. Our results show that speech-in-noise recognition is restricted in people with ASD. We speculate that perceptual impairments such as difficulties in vocal pitch perception might be relevant in explaining these difficulties in ASD.

Despite legislation to improve post-school outcomes for young adults with autism spectrum disorder, they experience poorer employment outcomes than their peers without disabilities. Data indicate persons with ASD experience lower employment rates, earn less money, work fewer hours, are less engaged in their communities, and live independently less frequently than their peers without disabilities. Furthermore, the earnings of individuals with ASD lag behind earnings of their peers both with and without disabilities. In order to help improve employment outcomes for youth with ASD, this chapter describes the characteristics contributing to employment of individuals with ASD, the factors influencing employment of individuals with ASD, and the research related to evidence-based practices for young adults with ASD.

Number Of Individuals

Given the increasing number of individuals diagnosed with autism spectrum disorder (ASD), there is a critical need to develop programs that facilitate positive behavior outcomes during the transition to adulthood. Furthermore, many adults with ASD do not have access to intervention programs due to remote locations, lack of qualified personnel, and/or long waitlists. This study, conducted within the context of a combined multiple baseline and changing criterion design, examined the use of videoconferencing (VC) to provide intervention from a remote location. Results showed that following intervention participants were able to independently perform the targeted skills and all targeted skills maintained during follow-up probes. All participants rated the intervention highly and said that they would recommend the intervention to others. These results are discussed in relation to potential avenues to increase access to services for individuals with ASD, particularly in remote and underserved areas, using VC.

Adults with autism spectrum disorder (ASD) and significant intellectual disability (ID) often have limited speech communication abilities. Abundant research supports use of augmentative and alternative communication (AAC) to enhance skills of children with ASD and ID, but less research has examined efficacy of AAC with non-speaking adults. In this study, three adults with ASD and significant ID were taught basic functional communication using the iPod Touch® with MyTalk Mobile® software within a single-case, multiple-probe across-subjects design. The iPod Touch® taught with most-to-least prompting increased participants’ independent manding, participants were able to discriminate between picture symbols, and participants’ manding generalized to a naturalistic setting with typically available preferred items. Implementation of AAC coincided with increases in speech for one participant. Results illustrate how an applied behavior analysis approach incorporating a speech generating device is effective in teaching communication to adults with ASD and significant ID.

Abstract Background Neurological, structural, and behavioral abnormalities are widely reported in individuals with autism spectrum disorder (ASD); yet there are no objective markers to date. We postulated that by using dominant and nondominant ear data, underlying differences in auditory evoked potentials (AEPs) between ASD and control groups can be recognized. Purpose The primary purpose was to identify if significant differences exist in AEPs recorded from dominant and nondominant ear stimulation in (1) children with ASD and their matched controls, (2) adults with ASD and their matched controls, and (3) a combined child and adult ASD group and control group. The secondary purpose was to explore the association between the significant findings of this study with those obtained in our previous study that evaluated the effects of auditory training on AEPs in individuals with ASD. Research Design Factorial analysis of variance with interaction was performed. Study Sample Forty subjects with normal hearing between the ages of 9 and 25 years were included. Eleven children and 9 adults with ASD were age- and gender-matched with neurotypical peers. Data Collection and Analysis Auditory brainstem responses (ABRs) and auditory late responses (ALRs) were recorded. Adult and child ASD subjects were compared with non-ASD adult and child control subjects, respectively. The combined child and adult ASD group was compared with the combined child and adult control group. Results No significant differences in ABR latency or amplitude were observed between ASD and control groups. ALR N1 amplitude in the dominant ear was significantly smaller for the ASD adult group compared with their control group. Combined child and adult data showed significantly smaller amplitude for ALR N1 and longer ALR P2 latency in the dominant ear for the ASD group compared with the control group. In our earlier study, the top predictor of behavioral improvement following auditory training was ALR N1 amplitude in the dominant ear. Correspondingly, the ALR N1 amplitude in the dominant ear yielded group differences in the current study. Conclusions ALR peak N1 amplitude is proposed as the most feasible AEP marker in the evaluation of ASD.

Abstract Date Presented Accepted for AOTA INSPIRE 2021 but unable to be presented due to online event limitations. The purpose of this study is to obtain deeper understanding of the challenges that young adults with autism spectrum disorder endure in their pursuit of establishing friendships. A mixed-methods study design was used. Participants were interviewed and completed the Autism Spectrum Quotient (AQ). Results showed that the participants still showed autistic traits, although each AQ component was similar to the norms. Three themes were emerged from the interview: intrinsic value of friendship, friendship as a partnership, Primary Author and Speaker: Megan C.
