Autism spectrum disorder (ASD) is a group of disabilities with impairments in physical, verbal, and behavior areas. Regardless the growing frequency of autism, no medicine has been formed for the management of the ASD primary symptoms. The most frequently prescribed drugs are off-label. Therefore, there is necessity for an advance tactic for the treatment of autism. The endocannabinoid system has a central role in ruling emotion and social behaviors. Dysfunctions of the system donate to the behavioral deficits in autism. Therefore, the endocannabinoid system represents a potential target for the development of a novel autism therapy. Cannabis and associated compounds have produced substantial research attention as a capable therapy in neurobehavioral and neurological syndromes. In this review we examine the potential benefits of medical cannabis and related compounds in the treatment of ASD and concurrent disorders.

Unique perceptual skills and abnormalities in perception have been extensively demonstrated in those with autism for many perceptual domains, accounting, at least in part, for some of the main symptoms. Several new hypotheses suggest that perceptual representations in autism are unrefined, appear less constrained by exposure and regularities of the environment, and rely more on actual concrete input. Consistent with these emerging views, a bottom-up, data-driven fashion of processing has been suggested to account for the atypical perception in autism. It is yet unclear, however, whether reduced effects of prior knowledge and top-down information, or rather reduced noise in the sensory input, account for the often-reported bottom-up mode of processing in autism. We show that neither is sufficiently supported. Instead, we demonstrate clear differences between autistics and neurotypicals in how incoming input is weighted against prior knowledge and experience in determining the final percept. Importantly, the findings tap central differences in perception between those with and without autism that are consistent across identified sub-clusters within each group.

A sense of being connected to other autistic people has been reported anecdotally. Friendships and connectedness may be important to autistic people and beneficial for their wellbeing. Our research aimed to understand the autistic community by interviewing 20 autistic people about their experiences of being connected to other autistic people. Participants were interviewed in person, over video, using a text-based software to type or over email. Participants detailed three parts of autistic community connectedness: a sense of belonging, social connection with autistic friends and political connectedness. The friendships autistic people had with one another were deemed to be very important to participants because it gave them confidence, provided companionship and made them happy. Some participants did not experience connectedness to the autistic community. These participants also found autism to be less important to their identity and had fewer positive feelings about being autistic. This research is important as it raises awareness that community connectedness is viewed as important to this group. It is possible that community connectedness may help protect the mental health of autistic people when they face stigma or negative life experiences in society.

Augmentative and Alternative Communication is an aided or unaided means of communication which supports existing communication abilities of an individual or replaces natural speech due to any speech and language disorder. The deficit could be developmental or acquired such as autism spectrum disorder, cerebral palsy, learning difficulties, dysarthria, dyspraxia or due to any acquired neurological condition such as aphasia and other degenerative disorders. Furthermore, it may be due to surgical procedures such as laryngectomy. Alternate means of communication have also been successfully used with COVID-19 patients. These tools may include pictures, symbols, signs or voice output devices. Parents of children with special needs and medical professionals have been reluctant in implementing the approach due to certain misconceptions. The aim of this review is to summarize the current evidence for the use of Augmentative and Alternative Communication with a range of disorders in relation to in relation to Pakistan.

6. Chan JKY, Leung PWL. Common outcome, different pathways: Social information-processing deficits in autism spectrum disorder and attention-deficit/hyperactivity disorder. World journal of psychiatry. 2022; 12(2): 286-97.

Social functioning is a key domain of impairment in both autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD). This review adopts the social information-processing model as the theoretical framework to compare and contrast the deficits of ASD and ADHD at each of the six steps of social information-processing. Both disorders show deficits at each step, but the nature and origins of the deficits are different. Thus, while both disorders exhibit a common outcome of social impairment, the exact pathways that each disorder traverses along the six steps of social information-processing are different. For ASD, there is a social knowledge/behaviour deficit arising from difficulties in social/emotional cue detection, encoding, and interpretation, leading to problems in joining and initiating social interaction. For ADHD, there is a performance deficit incurred by disruption arising from the ADHD symptoms of inattention and hyperactivity/impulsivity, while its acquisition capacity on social knowledge is relatively intact. The inattentive, intrusive, and impulsive behaviours of ADHD unsettle social interaction. Finally, this review proposes training targets for intervention along the six steps of the social information-processing model for ASD and ADHD, as well as areas for future research in further elucidating the social impairment of the two disorders.

Analysis of X-inactivation status in a Rett syndrome natural history study cohort. Molecular genetics & genomic medicine. 2022; 10(5): e1917.

BACKGROUND: Rett syndrome (RTT) is a rare neurodevelopmental disorder associated with pathogenic MECP2 variants. Because the MECP2 gene is subject to X-chromosome inactivation (XCI), factors including MECP2 genotypic variation, tissue differences in XCI, and skewing of XCI all likely contribute to the clinical severity of individuals with RTT. METHODS: We analyzed the XCI patterns from blood samples of 320 individuals and their mothers. It includes individuals with RTT (n = 287) and other syndromes sharing overlapping phenotypes with RTT (such as CDKL5 Deficiency Disorder [CDD, n = 16]). XCI status in each proband/mother duo and the parental origin of the preferentially inactivated X chromosome were analyzed. RESULTS: The average XCI ratio in probands was slightly increased compared to their unaffected mothers (73% vs. 69%, p = .0006). Among the duos with informative XCI data, the majority of individuals with classic RTT had their paternal allele preferentially inactivated (n = 180/220, 82%). In sharp contrast, individuals with CDD had their maternal allele preferentially inactivated (n = 10/12, 83%). Our data indicate a weak positive correlation between XCI skewing ratio and clinical severity scale (CSS) scores in classic RTT patients with maternal allele preferentially inactivated XCI (r(s) = 0.35, n = 40), but not in those with paternal allele preferentially inactivated XCI (r(s) = -0.06, n = 180). The most frequent MECP2 pathogenic variants were enriched in individuals with highly/moderately skewed XCI patterns, suggesting an association with higher levels of XCI skewing. CONCLUSION: These results extend our understanding of the pathogenesis of RTT and other syndromes with overlapping clinical features by providing insight into the both XCI and the preferential XCI of parental alleles.

9. Hartley C, Bird LA. Exploring the Influence of Object Similarity and Desirability on Children’s Ownership Identification and Preferences in Autism and Typical Development. Journal of autism and developmental disorders. 2022.

This study investigated how ownership identification accuracy and object preferences in children with autism spectrum disorder (ASD) are influenced by visual distinctiveness and relative desirability. Unlike typically developing (TD) children matched on receptive language (M age equivalents: 58.8-59.9 months), children with ASD had difficulty identifying another person’s property when object discriminability was low and identifying their own relatively undesirable objects. Children with ASD identified novel objects designated to them with no greater accuracy than objects designated to others, and associating objects with the self did not bias their preferences. We propose that, due to differences in development of the psychological self, ownership does not increase the attentional or preferential salience of objects for children with ASD.

BACKGROUND: Employment is often central to individuals’ lives. However, individuals with intellectual or developmental disabilities are often absent from the workplace, and little research has examined their interest in working. AIMS: This study examined whether people with intellectual and/or developmental disabilities want jobs; why they do or do not want jobs; and, if they want to work, what types of jobs they would like to have. MATERIALS AND METHODS: Our analyses consisted of 629 participants (379 male, 248 female, 2 unspecified) who participated in an interview. RESULTS: Results suggested that many individuals with intellectual or developmental disabilities want jobs. Our study identified gender differences in vocational interests and motivation for employment. There were no significant differences between age groups. DISCUSSION AND CONCLUSION: In the future, research could expand upon these findings by exploring how various factors, such as other social identities, affect vocational interests of individuals with intellectual or developmental disabilities.

Autistic traits and alcohol use in adolescents within the general population. European child & adolescent psychiatry. 2022.

It has been suggested that autistic traits are associated with less frequent alcohol use in adolescence. Our study seeks to examine the relationship between autistic traits and alcohol use in a large adolescent population. Leveraging data from the IMAGEN cohort, including 2045 14-year-old adolescents that were followed-up to age 18, we selected items on social preference/skills and rigidity from different questionnaires. We used linear regression models to (1) test the effect of the sum scores on the prevalence of alcohol use (AUDIT-C) over time, (2) explore the relationship between autistic traits and alcohol use patterns, and (3) explore the specific effect of each autistic trait on alcohol use. Higher scores on the selected items were associated with trajectories of less alcohol use from the ages between 14 and 18 (b = - 0.030; CI 95% = - 0.042, – 0.017; p < 0.001). Among adolescents who used alcohol, those who reported more autistic traits were also drinking less per occasion than their peers and were less likely to engage in binge drinking. We found significant associations between alcohol use and social preference (p < 0.001), nervousness for new situations (p = 0.001), and detail orientation (p < 0.001). Autistic traits (social impairment, detail orientation, and anxiety) may buffer against alcohol use in adolescence.

Autistic people contend with high levels of stigma in a wide array of cultures worldwide. There is a scarcity of literature on stigma in relation to autism in faith communities, with some limited research on this issue in Christian, Muslim and Hindu populations. There is virtually no research focussing on this topic in Jewish communities and to our knowledge, none at all within UK Jewish contexts. In this study, we aimed to explore experiences of stigma towards autism and sought views on what steps have and can be taken to reduce such stigma. Using an interpretative phenomenological analysis approach, we conducted semi-structured interviews with 10 participants within the UK Jewish community, including parents, rabbis, SENDCos, teachers, and headmasters of autistic children in both mainstream and specialist autistic schools. Interviews were conducted over 2 months in 2020. During analysis, 5 superordinate (central) themes and 13 subordinate themes were abstracted from the data. Superordinate themes included ‘Stigma not specific to the Jewish community’; ‘Considerable strides made’; ‘More a lack of knowledge or denial than stigma’; ‘Fear of stigma is a real concern but not widely prevalent’; and ‘Potent factors that reduce stigma in the Jewish community’. We recommend workshops for greater awareness and training for teachers and parents on autism and autistic children’s experiences. We also recommend the formation of specialist autism schools in other communities and promotion of positive narratives concerning autistic people, as this successfully reduced stigma within the Jewish community.

Timely data on service use and needs across the lifespan are essential to developing an effective and efficient service delivery system that is responsive to developmental issues. This study uses data from one of the largest statewide surveys conducted between 2017 and 2018 to compare service use and unmet needs among individuals on the autism spectrum across the lifespan. A statewide sample of 5792 caregivers of autistic children and adults were included in the study. Logistic regressions were conducted to compare service use and need among six age groups ranging from early childhood (0-5 years) to later adulthood (31+) while adjusting for sociodemographic characteristics. We found that the transition-age adult group (18-21 years) was less likely to receive services, including speech/language therapy, occupational therapy, one-on-one support, and social skill training, than adolescents. However, case management and mental health services increased with age. Young adults (22-30 years) were more likely to report unmet needs than both adolescents and transition-age adult groups. The use of services overall decrease and service needs increased compared to results from an earlier statewide survey that was conducting in 2009-2010. These results can be used to inform developmentally appropriate autism-related healthcare policies and service development and delivery. This study offers a more detailed look at differences between adult age subgroups that are novel. Further research is needed about the prevalence of ASD in adulthood, clinical trajectories, and outcomes in order to support autistic adults in getting the appropriate services and supports.

The broad autism phenotype commonly refers to sub-clinical levels of autistic-like behaviour and cognition presented in biological relatives of autistic people. In a recent study, we reported findings suggesting that the broad autism phenotype may also be expressed in facial morphology, specifically increased facial masculinity. Increased facial masculinity has been reported among autistic children, as well as their non-autistic siblings. The present study builds on our previous findings by investigating the presence of increased facial masculinity among non-autistic parents of autistic children. Using a previously established method, a ‘facial masculinity score’ and several facial distances were calculated for each three-dimensional facial image of 192 parents of autistic children (58 males, 134 females) and 163 age-matched parents of non-autistic children (50 males, 113 females). While controlling for facial area and age, significantly higher masculinity scores and larger (more masculine) facial distances were observed in parents of autistic children relative to the comparison group, with effect sizes ranging from small to medium (0.16 ≤ d ≤ .41), regardless of sex. These findings add to an accumulating evidence base that the broad autism phenotype is expressed in physical characteristics and suggest that both maternal and paternal pathways are implicated in masculinized facial morphology.

Autism spectrum disorder (ASD) is a neurodevelopmental disease featuring social interaction deficits and repetitive/stereotyped behaviours; the prevalence of this disorder has continuously increased. Progranulin (PGRN) is a neurotrophic factor that promotes neuronal survival and differentiation. However, there have not been sufficient studies investigating its effect in animal models of autism. This study investigated the effects of PGRN on autistic phenotypes in rats treated with valproic acid (VPA) and assessed the underlying molecular mechanisms. PGRN was significantly downregulated in the cerebellum at postnatal day 14 (PND14) and PND35 in VPA-exposed rats, which simultaneously showed defective social preference, increased repetitive behaviours, and uncoordinated movements. When human recombinant PGRN (r-PGRN) was injected into the cerebellum of newborn ASD model rats (PND10 and PND17), some of the behavioural defects were alleviated. r-PGRN supplementation also reduced cerebellar neuronal apoptosis and rescued synapse formation in ASD rats. Mechanistically, we confirmed that PGRN protects neurodevelopment via the PI3K/Akt/GSK-3β pathway in the cerebellum of a rat ASD model. Moreover, we found that prosaposin (PSAP) promoted the internalisation and neurotrophic activity of PGRN. These results experimentally demonstrate the therapeutic effects of PGRN on a rat model of ASD for the first time and provide a novel therapeutic strategy for autism.

INTRODUCTION: Robot-assisted Therapy (RAT) can improve the behavior of children with Autism Spectrum Disorder (ASD) in a spontaneous and entertaining way. There are no previous experiences of this type of inter vention in our country. OBJECTIVE: To describe a clinical experience of using RAT and its impact on the behaviors of a group of children with ASD, in a therapeutic context. PATIENTS AND METHOD: Quasi experimental clinical experience type study. 4 children with a clinical diagnosis of ASD were selected, supported by the ADOS-2 (Autism Diagnostic Observation Schedule); aged between 9 and 13 years, and normal IQ according to the WISC-III (Wechsler Intelligence Scale for Children). This study was approved by the Central Metropolitan Ethics Committee. Patients attended 10 structured robot-as sisted therapy sessions, working collaboratively in pairs. Workshop attendance and parent and child satisfaction were evaluated through surveys, the adaptive behavior with the Vineland scale, and so cial interaction with video coding guidelines. RESULTS: Patients presented a very good adherence and satisfaction with the activity. There was an improvement in socialization behaviors and social age. Video-coding showed an increase in social interaction and improvement in the behavior of the pa tients after attending workshops. CONCLUSIONS: We observed that the experience with RAT, adapted to the context of a Chilean public health center, was highly attractive and beneficial for patients with ASD, improving core symptoms such as difficulties in social interaction and behavioral problems.

INTRODUCTION: Temperament differences were shown in children with autism spectrum disorder (ASD); however, associations of temperament with ASD severity and accompanying psychiatric symptoms have yet to be studied. METHODS: We evaluated 58 ASD-diagnosed children’s temperaments through disorder severity and psychiatric symptoms and compared them with 58 typically developed children. We utilized the Children’s Behavior Questionnaire-Short Form, The Strengths and Difficulties Questionnaire (SDQ). The Childhood Autism Rating Scale (CARS) was used to evaluate psychiatric symptoms and ASD severity levels of children. RESULTS: Negative affect, effortful control, and perceptual sensitivity were found lower in ASD-diagnosed children and decreased with ASD severity. Effortful control was also found negatively correlated with scores of behavioral problems, hyperactivity, and total difficulties. Besides, anger/frustration was found predictive for conduct and peer problems, and total difficulty scores. CONCLUSION: Further studies are needed to verify and expand these pioneer findings.
