    Metastability in the brain is thought to be a mechanism involved in the dynamic organization of cognitive and behavioral functions across multiple spatiotemporal scales. However, it is not clear how such organization is realized in underlying neural oscillations in a high-dimensional state space. It was shown that macroscopic oscillations often form phase-phase coupling (PPC) and phase-amplitude coupling (PAC), which result in synchronization and amplitude modulation, respectively, even without external stimuli. These oscillations can also make spontaneous transitions across synchronous states at rest. Using resting-state electroencephalographic signals and the autism-spectrum quotient scores acquired from healthy humans, we show experimental evidence that the PAC combined with PPC allows amplitude modulation to be transient, and that the metastable dynamics with this transient modulation is associated with autistic-like traits. In individuals with a longer attention span, such dynamics tended to show fewer transitions between states by forming delta-alpha PAC. We identified these states as two-dimensional metastable states that could share consistent patterns across individuals. Our findings suggest that the human brain dynamically organizes inter-individual differences in a hierarchy of macroscopic oscillations with multiple timescales by utilizing metastability.

    Many parents have experienced difficulties in parenting children with autism. We, therefore, consider a more in-depth understanding that is necessary to explore the challenges facing parents and families to provide a better outcome for both. We interviewed 21 parents of 24 children with autism spectrum disorder (ASD) to qualitatively explore the challenges they experienced through a phenomenological framework. Four main aspects emerged as challenges to the parents: inadequate knowledge, psychological distress and stigma, lack of support, and barriers to services. These four themes reflect a lack of balance between the needs of caregivers and the services and resources or support available in the community to meet those needs. Our study contributes to an understanding of how parents perceive challenges, making it easier to take necessary action to meet their needs and ease their burden of stress. A concerted effort is needed to coordinate services across all disciplines to address these challenges.

    PURPOSE: Technological advances in robotics have brought about exciting developments in different areas such as education, training, and therapy. Recent research has suggested that the robot can be even more effective in rehabilitation, therapy, and education for individuals with Autism Spectrum Disorder (ASD). In this paper, a comprehensive review of robotic technology for children with ASD is presented wherein a large number of journals and conference proceedings in science and engineering search engines' databases were implicated.

    MATERIALS AND METHODS: A search for related literature was conducted in three search engines' databases, Web of Science, Scopus, and IEEE Xplore. Thematic keywords were used to identify articles in the recent ten years in titles, keywords, and abstracts. The retrieved articles were filtered, analysed, and evaluated based on specific inclusion and exclusion criteria.

    RESULTS: A total of 208 studies were retrieved, while 166 met the inclusion criteria. The selected studies were reviewed according to the type of robot, the participants, objectives, and methods. 68 robots were used in all studies, NAO robot was used in 30.5% of those studies. The total number of participants in all studies was 1671. The highest percentage of the studies reviewed were dedicated to augmenting the learning skills.

    CONCLUSIONS: Robots and the associated schemes were used to determine their feasibility and validity for augmenting the learning skills of autistic children. Most of the studies reviewed were focused on improving the social communication skills of autistic children and measuring the extent of robot mitigation of stereotyped autistic behaviours.Implications for rehabilitationSocial robots are not considered as promising tools to be utilized for rehabilitation of autistic children only, but also has been used for children and young people with severe intellectual disability.Rehabilitation for individuals with ASD using robots can augment their cognitive and social skills, but further studies should be conducted to clarify its effectiveness based on other factors such as sex, age and IQ of the participates.Robotic-based rehabilitation is not limited to the physical robots only, but virtual robots have been used also, whereas each of which can be used individually or simultaneously. However, further study is required to assess the extent of its efficiency and effectiveness for both cases.

    Alongside difficulties with communication and social interaction, autism is often accompanied by unusual sensory and perceptual experiences including enhanced visual performance on tasks that involve separating local parts from global context. This superiority may be the result of atypical integrative processing, involving feedback and lateral connections between visual neurons. The current study investigated the integrity of these connections in autistic adults by examining two psychophysics tasks that rely on these processes - collinear facilitation and contour integration. The relative contribution of feedback and lateral connectivity was studied by altering the timing of the target relative to the flankers in the collinear facilitation task, in 16 autistic and 16 non-autistic adults. There were no significant differences in facilitation between the autistic and non-autistic groups, indicating that for this task and participant sample, lateral and feedback connectivity appear relatively intact in autistic individuals. Contour integration was examined in a different group of 20 autistic and 18 non-autistic individuals, for open and closed contours to assess the closure effect (improved detection of closed compared to open contours). Autistic individuals showed a reduced closure effect at both short (150 ms) and longer (500 ms) stimulus presentation durations that was driven by better performance of the autistic group for the open contours. These results suggest that reduced closure in a simple contour detection paradigm is unlikely to be due to slower global processing. Reduced closure has implications for understanding sensory overload by contributing to reduced figure-ground segregation of salient visual features.

    In this work, gene expression in autism spectrum disorder (ASD) is analyzed with the goal of selecting the most attributed genes and performing classification. The objective was achieved by utilizing a combination of various statistical filters and a wrapper-based geometric binary particle swarm optimization-support vector machine (GBPSO-SVM) algorithm. The utilization of different filters was accentuated by incorporating a mean and median ratio criterion to remove very similar genes. The results showed that the most discriminative genes that were identified in the first and last selection steps included the presence of a repetitive gene (CAPS2), which was assigned as the gene most highly related to ASD risk. The merged gene subset that was selected by the GBPSO-SVM algorithm was able to enhance the classification accuracy.

    Caring for children with autism spectrum disorder (ASD) negatively impacts quality of life (QoL). This cross-sectional study aimed to determine the factors associated with perceived QoL and how problematic a child's autism-specific difficulties are among the main caregivers of children with ASD who attend specialized preschool programs at the National Autism Society of Malaysia and IDEAS Autism Centre located in Selangor and Kuala Lumpur. Utilizing the questions from Parts A and B of the Quality of Life in Autism Questionnaire (QoLA), the data from 116 responders were analyzed using univariate and multivariate linear regression. The mean scores of Part A and Part B were 88.55 ± 17.25 and 56.55 ± 12.35, respectively. The QoL was significantly associated with staying in an apartment/flat -11.37 (95%CI: -19.52, -1.17, p = 0.008), main caregivers attending two training sessions 10.35 (95%CI: 1.17, 19.52, p = 0.028), and more than three training sessions 13.36 (95%CI: 2.01, 24.70, p = 0.022). Main caregiver perceptions of their child's autistic-specific difficulties were significantly associated with not receiving additional help for childcare: no maid -13.54 (95%CI: -24.17, -12.91, p = 0.013); no grandparent -8.65 (95%: -14.33, -2.96, p = 0.003); and main caregivers not having asthma 8.44 (95%CI: 0.02, 16.86, p = 0.049). These identified factors can be considered to inform main caregivers and health care providers on targeted ways to improve the QoL of main caregivers.

    Background: This study evaluates the effectiveness of parent-assisted children's friendship training intervention for enhancing friendship quality and social skills among children with autism spectrum disorders (ASD). We conducted a quasi-experimental study to investigate the effective outcomes of social skills and friendship quality in the pre-and post-parent-assisted CFT intervention phases; Methods: to conduct a 12-week field session, 30 children with their parents were selected. The Social Skills Improvement System Rating Scales and the Quality of Play Questionnaire-Parent were used to assess the effectiveness of the parent-assisted children's friendship training during pre-and post-intervention. A semi-structured interview with parents was conducted at the end of the session; Results: findings revealed that intervention improved the social skills of these children. Additionally, the friendship quality of children with ASD improved before and after the intervention, however, engagement remained unchanged. Parents also showed some sort of improvement after the session as they reported a heightened sense of fear and resistance, awareness, learning and adjustment, change is not easy, and identifying support; Conclusions: there was clear evidence that children with ASD benefitted from parent-assisted CFTs in terms of social skills and friendship quality. However, larger and controlled studies are required to draw firm conclusions about this kind of intervention.

    While scholars have investigated positive body image across diverse populations, extant theory largely excludes those with differing socio-cognitive experiences, such as autistic individuals. Using constructivist grounded theory, this study sought to develop a grounded theory of positive body image in autistic individuals. One-to-one interviews with photo-elicitation were conducted with 20 autistic adults (7 women, 8 men, 5 non-binary/agender; aged 18-53 years) from the United Kingdom. Through a process of open, axial, and focused coding, a grounded theory was developed around a core category of positive body image in autistic adults and was found to comprise six themes: body connection, body acceptance, appreciating body functionality and neurodivergent strengths, having a body-positive protective filter, taking care of the body, and body and appearance neutrality. Our findings suggest that some aspects of positive body image in autistic individuals are consistent with those found in neurotypical adults. However, positive body image in autistic individuals further encompasses both the sensory (i.e., how the body is felt) and aesthetic (i.e., how the body is seen) body. These findings may stimulate research aimed at improving positive body image in autistic populations.

    Asperger's Syndrome is a distinct variant of autism, with a prevalence rate of 10 to 26 per 10,000 of normal intelligence, and 0.4 per 10,000 in those with mild mental retardation. The syndrome now has its own clinical entity and diagnostic criteria. It is being officially listed in the ICD-10 under pervasive developmental disorder. Two such cases are described in this article. Case One lacked the ability to relate to others, was excessively preoccupied with the late actor P. Ramlee and demonstrated a peculiar behaviour of holding on to toothbrushes in his early childhood. Cognitively, he was unable to synthesise words into meaningful sentences. Similarly, Case Two was unable to relate well to others and was preoccupied with the planets and its constellations. Though he appeared intelligent with an IQ score of 101, he was unable to follow instructions at school. Both children had motor clumsiness and fulfilled the criteria for the diagnosis of Asperger's Syndrome.

    Autism has been associated with a low antioxidant defense mechanism, while honey has been known for decades for its antioxidant and healing properties. Determination of stingless bee honey (KH) effects on antioxidant enzyme activities and oxidative damage in Autism Lymphoblastoid Cell Line (ALCL) was performed. ALCL and its normal sibling pair (NALCL) were cultured in RPMI-1640 medium at 37°C and 5% CO2. ALCL was treated with 400 μg/mL KH (24 h), and oxidative stress marker, malondialdehyde (MDA), and antioxidant enzyme activities (catalase (CAT), glutathione peroxidase (GPx), and superoxide dismutase (SOD)) were measured via enzyme-linked immunosorbent assay (ELISA), while deoxyribonucleic acid (DNA) damage was determined via comet assay. Low SOD activity (p < 0.05) and high MDA level (p < 0.05) were observed in ALCL compared to NALCL. Higher grade (Grades 2 and 3) of DNA damage was highly observed (p < 0.05) in ALCL compared to NALCL, whereas lower grade (Grades 0 and 1) DNA damage was highly detected (p < 0.05) in NALCL compared to ALCL. KH treatment caused a significant increase in SOD and GPx activities (p < 0.05) in ALCL compared to untreated ALCL. Correspondingly, KH treatment reduced the Grade 2 DNA damage (p < 0.05) in ALCL compared to untreated ALCL. CAT activity showed no significant difference between all three groups, while the MDA level showed no significant difference between treated and untreated ALCL. In conclusion, KH treatment significantly reduced the oxidative stress in ALCL by increasing the SOD and GPx antioxidant enzyme activities, while reducing the DNA damage.

    Autism spectrum disorder (ASD) is a complex neurodevelopmental disability that is frequently associated with food refusal, limited food repertoire and high-frequency single food intake mainly among children with ASD. Provision of nutrition can be very challenging due to the fact of these behavioural problems, either for the parents or special educators. Healthy nutrition is associated with providing and consuming nutritious food with results being in a good state of health. Semi-structured focus group discussions (FGDs) were conducted among 20 participants at a National Autism Centre to explore their understanding towards healthy nutrition. They were parents and special educators who were actively involved with children with ASD. A series of discussions were transcribed verbatim, and four researchers examined each transcript. Inductive analysis linking codes into main thematic categories was conducted using the constant comparison approach across the full data set. The outcome suggested that participants had limited knowledge relating to the proper dietary and nutritional needs of the children. The key messages from the discussion provide a foundation on the development of a nutrition education module which involves primary caretakers of children with ASD.

    Epilepsy is a chronic neurological disorder characterized by the rapid occurrence of epileptic seizures affecting approximately 70 million people worldwide[1,2]. The quality of life of people with epilepsy (PWE) is challenged by a series of comorbidities that might include neurologic and neuropsychiatric disorders (cognitive decline, depression, anxiety, schizophrenia, and autism) as well as metabolic, cardiovascular and respiratory diseases[3]. Neurobehavioral and other comorbidities might share a reciprocal and complex relationship with epileptogenesis and ictogenesis thus biomarkers of the former might be useful for the prediction of the latter and vice versa[4].

    Objective: Parents’ positive attitudes and psychological wellbeing play an important role in the development of the children with developmental disability. This study aimed to measure the prevalence of psychological problems among mothers of children with autism disorder, intellectual disability, and Down syndrome. The second aim was to assess the differences in mothers’ attitudes and psychological problems among their children with intellectual disability, autism disorder, and Down syndrome. The third aim was to identify whether negative attitude was a predictor of psychological problems in these mothers.
    Methods: In this study, 112 mothers of children having mild and moderate levels of autism disorder, Down syndrome, and intellectual disability were assessed using the Parental Attitude Scale and General Health Questionnaire–28.
    Results: Overall, mothers of children with intellectual disability were found to have the most negative attitude towards their child. Mothers of children with autism disorder exhibited higher scores on somatic symptoms, anxiety, and social dysfunction when compared with their counterparts with Down syndrome and intellectual disability. Negative attitude was a significant predictor of psychological problems.
    Conclusion: Parental attitudes and psychological problems would vary among mothers of children with different types of developmental disability.

    The disorder of autism is widely recognised throughout the world. However, the diagnostic criteria and theories of autism are based on research predominantly conducted in Western cultures. Here we compare the expression of autistic traits in a sample of neurotypical individuals from one Western culture (UK) and two Eastern cultures (India and Malaysia), using the Autism-spectrum Quotient (AQ) in order to identify possible cultural differences in the expression of autistic traits. Behaviours associated with autistic traits were reported to a greater extent in the Eastern cultures than the Western culture. Males scored higher than females and science students scored higher than non-science students in each culture. Indian students scored higher than both other groups on the Imagination sub-scale, Malaysian students scored higher than both other groups on the Attention Switching sub-scale. The underlying factor structures of the AQ for each population were derived and discussed.

    The effect of education on children with autism serves as a relative cure for their deficits. As a result of this, they require special techniques to gain their attention and interest in learning as compared to typical children. Several studies have shown that these children are visual learners. In this study, we proposed a Visual Hybrid Development Learning System (VHDLS) framework that is based on an instructional design model, multimedia cognitive learning theory, and learning style in order to guide software developers in developing learning systems for children with autism. The results from this study showed that the attention of children with autism increased more with the proposed VHDLS framework.

    Cultural background might influence knowledge and attitudes regarding autism, influencing willingness to interact. We studied whether beliefs, knowledge, contact, and attitude differed between the UK and Malaysia. With mediation analyses, we studied how these factors influenced willingness to interact. Autism was more often linked to food in the UK, and to upbringing in Malaysia. Knowledge, contact, and acceptance were greater in the UK. When excluding psychology students, Malaysian students were less willing to interact with autistic people. Knowledge and contact appeared to improve acceptance, but acceptance did not mediate the relation between country, beliefs, knowledge, and experience; and willingness to interact. Knowledge and contact regarding autism might improve acceptance in different cultures, but how acceptance could improve interaction is unclear.
