Autism spectrum disorder (ASD) is characterized by social communication deficits, impaired social interaction, and restricted and stereotyped behaviours and interests. The typical onset is during early childhood. Behaviourally, people with ASD have difficulties in tolerating proximity. Insecure attachment is frequently observed. At the cognitive level, people with ASD have selective difficulties in mentalizing or ‘theory of mind’, possibly related to a dysfunctional mirror neuron system and alterations of the oxytocin system. Conversely, many with ASD (particularly those formerly diagnosed with Asperger’s syndrome) have superior technical skills. It has been hypothesized that the brains of individuals with ASD are skewed to maleness, possibly linked to genomic imprinting of paternal genes. The preservation of genes that predispose to ASD may have undergone sexual selection fostering ‘slow’ life-history strategies. None of the evolutionary hypotheses on ASD is conclusive so far, but open to empirical testing.

The amygdala is a core node in the social brain which exhibits structural and functional abnormalities in Autism spectrum disorder and there is evidence that the mirror neuron system (MNS) can functionally compensate for impaired emotion processing following amygdala lesions. In the current study, we employed an fMRI paradigm in 241 subjects investigating MNS and amygdala responses to observation, imagination and imitation of dynamic facial expressions and whether these differed in individuals with higher as opposed to lower autistic traits. Results indicated that individuals with higher compared to lower autistic traits showed reduced left amygdala responses to imitation and enhanced responses in the left superior temporal sulcus (STS) of the MNS to observation, imagination and imitation. Additionally, functional connectivity between the left amygdala and the left STS as well as some other MNS regions was increased in individuals with higher autistic traits, especially during imitation of fearful expressions. The amygdala-MNS connectivity significantly moderated autistic group differences on recognition memory for fearful faces and real-life social network indices, indicating that increased amygdala-MNS connectivity could diminish the social behavioral differences between higher and lower autistic trait groups. Overall, findings demonstrate decreased imitation-related amygdala activity in individuals with higher autistic traits in the context of increased cortical MNS activity and amygdala-MNS connectivity which may functionally compensate for amygdala dysfunction and social deficits. Training targeting the MNS may capitalize on this compensatory mechanism for therapeutic benefits in Autism spectrum disorder.

Abstract Autism spectrum disorder (ASD) is a condition of multiple origins. It is characterised by a range of behaviour patterns, in addition to disturbed social and emotional functioning. Of note, early therapy is conducive to better treatment results. A few recently discussed therapies have a particularly positive impact on children with ASD. Corbett et al. [2] proposed Sense Theatre. This involves instilling appropriate behaviours and communication patterns into the afflicted individual through acting. Role-playing and other similar techniques also offer an opportunity for children with ASD to improve their areas of empathy and social cooperation. With regard to bio-feedback-related techniques, Friedrich et al. [3] was noted for developing the Brain-computer method, a system of game interface connected to an external device. The method targets the mirror neuron system (MNS) in order to enhance cognitive, emotional and behavioural functions through neurofeedback. An approach put forward by Solomon et al. [10] is called ‘Play and Language for Autistic Youngsters (PLAY) Project Home Consultation’. Herein, volunteers visit patients’ homes on a regular basis to engage the children in play and games, after which they discuss with parents, the issues that came up. The PLAY reduces guardians’ stress levels and improves children’s skills. A pharmacological method is that of administering sulphoraphane [9], which reduces damaging effects. As others claim [8,1,7], other dietary approaches prove efficient as well. In summation, an early intervention and the employment of a multimodal treatment approach can be of importance for enhancing the life of ASD-affected children.

Social Encounters

Two different neural systems and their associated functions have been identified by social neuroscience as important factors of social interaction: the mirror neuron system (MNS) and the mentalizing system (MENT), mirroring and mentalizing, respectively. Since anomalies in social behavior are core to autism spectrum disorder, observation of impairments in this disease is particularly interesting for research on those functions. Yet, the majority of studies concentrated respectively on one of the two networks or associated abilities or did not take into account clinical populations to learn more about the synergy of both during social encounters. This study is the first to examine those complex skills between two diagnostic groups using an appropriate behavioral approach. A new set of stimuli allowed to compare mirroring and mentalizing by addressing both recognition abilities with the same visual input, controlling for potentially confounding variables.Results indicate anomalies in the detection of mood, but not in the detection of actions in autism, suggesting impairments in mentalizing but normal functioning of mirroring abilities. Since no differences between mirroring and mentalizing in the group of healthy control participants were detected, findings can be interpreted as an indication for a primal separation of both functions or neural networks, respectively. However, a synergy seems to be probable, but needs to be clarified by further research. Additionally, a significantly higher number of unanswered trials was observed in persons with autism, indicating a tendency of avoidance of uncertainty in autism.

Spectrum Disorder

Autism spectrum disorder (ASD) is defined by deficits in social communication and interaction, and restricted and repetitive behaviors and interests. Although current diagnostic conceptualizations of ASD do not include emotional difficulties as core deficits, the disorder is associated with emotion dysregulation across the lifespan, with considerable implications for long-term psychological, social, and educational outcomes. The overarching goal of this chapter is to integrate existing knowledge of emotion dysregulation in ASD and identify areas for further investigation. The chapter reviews the prevalence and expressions of emotion dysregulation in ASD, discusses emerging theoretical models that frame emotion dysregulation as an inherent (rather than associated) feature of ASD, presents neurobiological findings and mechanisms related to emotion dysregulation in ASD, and identifies continuing controversies and resulting research priorities.

Students With Autism

Students with Autism Spectrum Disorder are likely to demonstrate social impairments that contribute to challenging behaviors and academic difficulties. As a result, the task of improving social communication skills is a critical component to any educational program for this population. Scripting provides an evidence-based and versatile option for improving social communication, yielding valuable results while requiring limited time and resource preparation from educators. In this article, we present step by step guidance to support practitioners in using scripting interventions. Considerations are discussed for adapting this intervention to meet the needs of students across the autism spectrum and links to resources for strengthening implementation and including other evidence-based practices.

Abstract Rationale Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by deficits in social communication and interaction and restricted, repetitive behaviors. The unmet medical need in ASD is considerable since there is no approved pharmacotherapy for the treatment of these deficits in social communication, interaction, and behavior. Cariprazine, a dopamine D3-preferring D3/D2 receptor partial agonist, is already approved for the treatment of schizophrenia and bipolar I disorder in adults; investigation in patients with ASD is warranted. Objectives The aim of this study was to investigate the effects of cariprazine, compared with risperidone and aripiprazole, in the rat prenatal valporic acid (VPA) exposure model on behavioral endpoints representing the core and associated symptoms of ASD. Methods To induce the ASD model, time-mated Wistar rat dams were treated with VPA during pregnancy. Male offspring were assigned to groups and studied in a behavioral test battery at different ages, employing social play, open field, social approach-avoidance, and social recognition memory tests. Animals were dosed orally, once a day for 8 days, with test compounds (cariprazine, risperidone, aripiprazole) or vehicle before behavioral assessment. Results Cariprazine showed dose-dependent efficacy on all behavioral endpoints. In the social play paradigm, only cariprazine was effective. On the remaining behavioral endpoints, including the reversal of hyperactivity, risperidone and aripiprazole displayed similar efficacy to cariprazine. Conclusions In the present study, cariprazine effectively reversed core behavioral deficits and hyperactivity present in juvenile and young adult autistic-like rats. These findings indicate that cariprazine may be useful in the treatment of ASD symptoms.

Abstract Background Autism spectrum disorder (ASD) is a chronic neurodevelopmental condition with a prevalence rate above 1%, characterized by deficits in social communication and interaction; restrictive, repetitive patterns of behavior, interests, or activities; and a preference for sameness and routines. The majority of adult ASD patients suffer from comorbid conditions such as depression and anxiety. Therapy options for adult ASD patients are lacking, with presently no available evidence-based interventions in Germany. Recently, two interventions to improve social responsiveness have been published. FASTER (“Freiburger Asperger-Spezifische Therapie für ERwachsene” = Freiburg Asperger-specific therapy for adults) is a manualized group psychotherapy program including three modules on psychoeducation, stress regulation management, and non-verbal and verbal social communication training with videotaped tasks. SCOTT&EVA (“Social Cognition Training Tool”, and its enhancement “Emotionen Verstehen und Ausdruecken” = understanding and expressing emotions) is a computer-based training program to enhance social cognition including video and audio material of emotional expressions and complex real-life social situations. Initial studies for both programs have shown good feasibility and efficacy. Methods Three hundred sixty adult participants with an autism spectrum disorder (ASD) will take part in a randomized controlled three-armed multi-center trial to prove the efficacy of manualized group psychotherapy and a manualized computer-based training program. Both interventions will be compared with a treatment as usual (TAU) group, aiming to establish evidence-based psychotherapy approaches for adult individuals with ASD. The primary outcome is evaluated by parents, spouses, or others who have sufficient insight into the respective participant’s social communication and interaction, and will be measured with the Social Responsiveness Scale. First, each of both interventions will be compared to TAU. If at least one of the differences is significant, both interventions will be compared against each other. The primary outcome will be measured at baseline (T0) and 4 months after baseline (T1). Discussion The trial is the first to validate psychiatric therapeutic and training interventions for adult ASD patients in Germany. A trial is needed because the prevalence of ASD in adulthood without intellectual disability is high, and no evidence-based intervention can be offered in Germany. Trial registration German Clinical Trial Register DRKS00017817. Registered on 20 April 2020.
