Patient Cooperation

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by persistent deficits in social communication and the presence of restricted interests and repetitive behaviours. Comorbidities following ASD, such as seizure, intellectual disability, and sensory impairment worsen patients’ ability to care for themselves. We present the case of a 22-year-old man with autism, intellectual disability and visual impairment who had recurrent pain in his upper and lower left posterior teeth that had cavities. On the first visit, the patient was observed and had panoramic x-ray. Clinical examination could not be done properly due to lack of patient cooperation. Restoration, pulp capping, tooth extraction, and odontectomy were planned under general anaesthesia.

The Individual

As a major neurodevelopmental disorder, Autism Spectrum Disorder (ASD) encompasses deficits in communication and repetitive and restricted interests or behaviors in childhood and adolescence. Its etiology may come from either a genetic, epigenetic, neurological, hormonal, or an environmental cause, generating pathways that often altogether play a synergistic role in the development of ASD pathogenesis. Furthermore, the metabolic origin of ASD should be important as well. A balanced diet consisting of the essential and special nutrients, alongside the recommended caloric intake, is highly recommended to promote growth and development that withstand the physiologic and behavioral challenges experienced by ASD children. In this review paper, we evaluated many studies that show a relationship between ASD and diet to develop a better understanding of the specific effects of the overall diet and the individual nutrients required for this population. This review will add a comprehensive update of knowledge in the field and shed light on the possible nutritional deficiencies, metabolic impairments (particularly in the gut microbiome), and malnutrition in individuals with ASD, which should be recognized in order to maintain the improved socio-behavioral habit and physical health.

Autism spectrum disorder (ASD) is a prevalent neurodevelopmental disorder characterized by impairments in social communication and social interaction, and the presence of repetitive behaviors and/or restricted interests. In the past few years, large-scale whole-exome sequencing and genome-wide association studies have made enormous progress in our understanding of the genetic risk architecture of ASD. While showing a complex and heterogeneous landscape, these studies have led to the identification of genetic loci associated with ASD risk. The intersection of genetic and transcriptomic analyses have also begun to shed light on functional convergences between risk genes, with the mid-fetal development of the cerebral cortex emerging as a critical nexus for ASD. In this review, we provide a concise summary of the latest genetic discoveries on ASD. We then discuss the studies in postmortem tissues, stem cell models, and rodent models that implicate recently identified ASD risk genes in cortical development.

And Behavior

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication and interaction, and restricted interests and behavior patterns. These characteristics are considered as a continuous distribution in the general population. People with ASD show atypical temporal processing in multisensory integration. Regarding the flash–beep illusion, which refers to how a single flash can be illusorily perceived as multiple flashes when multiple auditory beeps are concurrently presented, some studies reported that people with ASD have a wider temporal binding window and greater integration than typically developed people; others found the opposite or inconsistent tendencies. Here, we investigated the relationships between the manner of the flash–beep illusion and the various dimensions of ASD traits by estimating the degree of typically developed participants’ ASD traits including five subscales using the Autism-Spectrum Quotient. We found that stronger ASD traits of communication and social skill were associated with a wider and narrower temporal binding window respectively. These results suggest that specific ASD traits are differently involved in the particular temporal binding processes of audiovisual integration.

Biological Outcomes

Autism is a neurodevelopmental disorder whose diagnosis is based on three behavioral criteria: unusual reciprocal social interactions, deficits in communication, and stereotyped repetitive behaviors with restricted interests. A large number of de novo single gene mutations and chromosomal deletions are associated with autism spectrum disorders. Based on the strong genetic evidence, mice with targeted mutations in homologous genes have been generated as translational research tools. Mouse models of autism have revealed behavioral and biological outcomes of mutations in risk genes. The field is now poised to employ the most robust phenotypes in the most replicable mouse models for preclinical screening of novel therapeutics.

Motor Abnormalities

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by social communication deficits and restricted interests and behaviors which begin very early in life. In about a quarter of cases, the symptoms emerge about 18–24 months after a period of normal development, a phenomenon commonly described as early regression. However, marked functional decline can also occur in persons with autism after a relatively stable childhood. As opposed to early regression, which occurs in normally developing children, late regression occurs typically in adolescents with an established diagnosis of autism. Apart from their occasional mention in the literature, these individuals have not been examined systematically. This Brief Report describes the presentation, comorbidity and short-term outcome of 20 persons with ASD who developed late regression. The mean age of onset of regression was 13 years. One of the earliest symptoms was an increase in obsessive slowing and compulsive rituals. Other symptoms included motor abnormalities, aggression and mood disturbance. The most common comorbid disorder was catatonia occurring in 17 patients. Despite treatment with several modalities, the outcome was often suboptimal. These findings suggest that catatonia is a common cause of late regression in persons with autism. Clinical and research implications are discussed.

The Brain

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that is accompanied by social deficits, repetitive and restricted interests, and altered brain development. The majority of ASD patients suffer not only from ASD itself but also from its neuropsychiatric comorbidities. Alterations in brain structure, synaptic development, and misregulation of neuroinflammation are considered risk factors for ASD and neuropsychiatric comorbidities. Electroencephalography has been developed to quantitatively explore effects of these neuronal changes of the brain in ASD. The pineal neurohormone melatonin is able to contribute to neural development. Also, this hormone has an inflammation-regulatory role and acts as a circadian key regulator to normalize sleep. These functions of melatonin may play crucial roles in the alleviation of ASD and its neuropsychiatric comorbidities. In this context, this article focuses on the presumable role of melatonin and suggests that this hormone could be a therapeutic agent for ASD and its related neuropsychiatric disorders.

Core Symptoms

Abstract Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder with main core symptoms including deficits in social-communication abilities and repetitive behaviors/restricted interests. ASD affects 1 of 88 children worldwide and currently there is no sufficiently effective treatment that alleviates its core deficits. In our previous studies, we have shown that both MSC and MSC-exo can ameliorate core ASD-like symptoms of the BTBR multifactorial mouse model of autism. Furthermore, we have demonstrated that the MSC-exo migrate to distinct neuropathological areas in several mouse models, including the frontal cortex and cerebellum in BTBR mice. In contrast to BTBR mice, which is a multifactorial model of autism, the Shank3B KO mouse is used to study ASD which develops due to a specific genetic mutation. Here we demonstrate that intranasal treatment with MSC-exo improves the social behavior deficit in multiple paradigms, increases vocalization and reduces repetitive behaviors. We also observed an increase of GABRB1 in the prefrontal cortex. Taken together, our data indicate that intranasal treatment with MSC-exo improves the core ASD-like deficits of in this mouse model autism and therefore has the potential to treat ASD patients carrying the Shank3 mutation.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by social-communication deficits and the presence of restricted interests and/or repetitive behaviors. There are currently no psychopharmacological agents approved to treat core symptoms of ASD. As such, behavioral interventions are the most effective method for improving symptoms. In the current chapter, we propose that administering the neuropeptide oxytocin in conjunction with evidence-based behavioral interventions may lead to improved outcomes in social-communication for children with ASD. From a mechanistic perspective, we hypothesize that oxytocin may “prime” social reward circuitry in the brain, thereby allowing behavioral interventions designed to increase social motivation/initiation to be more effective. Extant literature related to theories of ASD, oxytocin administration in children with ASD, and behavioral intervention outcomes are reviewed, and considerations for individual characteristics (e.g., genetics, oxytocin availability, age, behavioral profile, etc.) that may affect efficacy are discussed.

Autism is a lifelong neurodevelopmental disorder that affects approximately 1% of children worldwide. Children with autism have difficulties in social interactions and communication and often engage in repetitive behaviors or have restricted interests (American Psychiatric Association, 2013). As a result of their child’s autism diagnosis, parents of children with autism often experience increased stress and poorer psychological well-being. Moreover, relationships within the family (e.g., marital relationship) may be negatively impacted. Addressing the needs of family members, particularly parents, is critical, as decades of research have shown that parents’ psychological well-being can affect the way that parents interact with their children. These interactional patterns can, in turn, impact children’s development in many of the areas that are affected by autism, including the social and emotional, language, and cognitive domains. The government of Qatar has recently taken steps to address the needs of children with autism and their families. The overarching aim of the Qatar National Autism Plan is to improve the lives of individuals with autism and their families. The six pillars of the National Autism Plan are designed to address the needs of individuals with autism and their families in areas such as raising awareness about autism, receiving early diagnosis, and accessing treatment and education. Once these needs are met, it is likely that the families of children with autism in Qatar can flourish. However, there are likely to be other challenges and unmet needs that the National Autism Plan does not address, and it was with this in mind that this first comprehensive study of families of children with autism in Qatar was undertaken.

Acting In Concert

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that affects social interaction and communication, with restricted interests, activity and behaviors. ASD is highly familial, indicating that genetic background strongly contributes to the development of this condition. However, only a fraction of the total number of genes thought to be associated with the condition have been discovered. Moreover, other factors may play an important role in ASD onset. In fact, it has been shown that parental conditions and in utero and perinatal factors may contribute to ASD etiology. More recently, epigenetic changes, including DNA methylation and micro RNA alterations, have been associated with ASD and proposed as potential biomarkers. This review aims to provide a summary of the literature regarding ASD candidate genes, mainly focusing on synapse formation and functionality and relevant epigenetic and environmental aspects acting in concert to determine ASD onset.
