Review
OBJECTIVE
The relationship between sex/gender differences and autism has attracted a variety of research ranging from clinical and neurobiological to etiological, stimulated by the male bias in autism prevalence. Findings are complex and do not always relate to each other in a straightforward manner. Distinct but interlinked questions on the relationship between sex/gender differences and autism remain underaddressed. To better understand the implications from existing research and to help design future studies, we propose a 4-level conceptual framework to clarify the embedded themes.
METHOD
We searched PubMed for publications before September 2014 using search terms "'sex OR gender OR females' AND autism." A total of 1,906 articles were screened for relevance, along with publications identified via additional literature reviews, resulting in 329 articles that were reviewed.
RESULTS
Level 1, "Nosological and diagnostic challenges," concerns the question, "How should autism be defined and diagnosed in males and females?" Level 2, "Sex/gender-independent and sex/gender-dependent characteristics," addresses the question, "What are the similarities and differences between males and females with autism?" Level 3, "General models of etiology: liability and threshold," asks the question, "How is the liability for developing autism linked to sex/gender?" Level 4, "Specific etiological-developmental mechanisms," focuses on the question, "What etiological-developmental mechanisms of autism are implicated by sex/gender and/or sexual/gender differentiation?"
CONCLUSIONS
Using this conceptual framework, findings can be more clearly summarized, and the implications of the links between findings from different levels can become clearer. Based on this 4-level framework, we suggest future research directions, methodology, and specific topics in sex/gender differences and autism.

Review
This systematic mapping review mapped current knowledge of equine-assisted interventions for people with autism to help guide future practice and research. Thirty-three studies including children and adolescents with autism, 3 of which confirmed diagnoses, were reviewed. Five types of equine-assisted activities were identified across 25 studies, with reported improvements in behavior, social interaction, and communication. Four types of equine-assisted therapies were identified across 8 studies, with reported improvements in motor control and self-care. Different approaches to therapeutic riding and hippotherapy, the most studied interventions, were evident. While this literature reflected early scientific development, it offered broad proof of concept that equine-assisted interventions can benefit children and adolescents with autism. Promising outcomes support continued investigation focused on standardization, appropriateness, and efficacy.

This systematic review describes a set of practices that have evidence of positive effects with autistic children and youth. This is the third iteration of a review of the intervention literature (Odom et al. in J Autism Dev Disorders 40(4):425-436, 2010a; Prevent School Fail 54(4):275-282, 2010b; Wong et al. in https://autismpdc.fpg.unc.edu/sites/autismpdc.fpg.unc.edu/files/imce/documents/2014-EBP-Report.pdf ; J Autism Dev Disorders 45(7):1951-1966, 2015), extending coverage to articles published between 1990 and 2017. A search initially yielded 31,779 articles, and the subsequent screening and evaluation process found 567 studies to include. Combined with the previous review, 972 articles were synthesized, from which the authors found 28 focused intervention practices that met the criteria for evidence-based practice (EBP). Former EBPs were recategorized and some manualized interventions were distinguished as meeting EBP criteria. The authors discuss implications for current practices and future research.

Review
Cerebellar research has focused principally on adult motor function. However, the cerebellum also maintains abundant connections with nonmotor brain regions throughout postnatal life. Here we review evidence that the cerebellum may guide the maturation of remote nonmotor neural circuitry and influence cognitive development, with a focus on its relationship with autism. Specific cerebellar zones influence neocortical substrates for social interaction, and we propose that sensitive-period disruption of such internal brain communication can account for autism's key features.

Review
Since the initial psychological report by Leo Kanner in 1943, relatively little formal biochemical/neurological research on the cause of autism, other than peripheral searches for genomic mutations, had been carried until the end of the 20th century. As a result of studies on twin sets and the conclusion that autism was largely a hereditary defect, numerous investigations have sought various genetic faults in particular. However, such studies were able to reveal a plausible etiology for this malady in only a small percentage of instances. Key bio-molecular characteristics of this syndrome have been uncovered when the potential roles of the glia were studied in depth. Findings related to biochemical deficiencies appearing early in the newborn, such as depressed IGF-1 (insulin-like growth factor #1) in neurogenesis/myelination, are becoming emphasized in many laboratories. Progress leading to timely diagnoses and subsequent prevention of central nervous system dysconnectivity now seems plausible. The tendency for an infant to develop autism may currently be determinable and preventable before irreversible psychosocial disturbances become established. These discussions about glial function will be inter-spersed with comments about their apparent relevance to autism. The concluding portion of this presentation will be a detailed review and summation of this diagnosis and prevention proposition.

PURPOSE OF REVIEW
There is considerable overlap between the features of avoidant-restrictive food intake disorder (ARFID) and autism. The purpose of this scoping review is to provide an overview of studies published on ARFID and autism in 2022 and the first half of 2023.
RECENT FINDINGS
ARFID and autism are highly heritable conditions that often co-occur. In a large autism cohort, 21% of participants and 17% of their parents presented with avoidant-restrictive features. Of children diagnosed with ARFID, 8.2-54.8% are autistic. More than half of individuals with ARFID also have other neurodevelopmental, psychiatric, or somatic diagnoses. Anxiety, depression, sleep disorders, and learning difficulties are particularly common co-occurring issues. Various strategies have been developed to support autistic children with feeding difficulties. It appears that their feeding difficulties, particularly sensory sensitivities, food preferences, and mealtime rituals and routines frequently persist into adolescence and adulthood, but research on optimal support for adults and adolescents is still scarce. Untreated ARFID in autistic individuals may lead to serious complications.
SUMMARY
Individuals seeking specialist care for autism, eating disorders, or gender dysphoria should be screened for ARFID. More research is needed on how to support autistic adolescents and adults with features of ARFID.

INTRODUCTION
Autism or ASDs are neurodevelopmental disorders that affect socio-communicative development, interests, and a restricted and stereotyped pattern of interests and behavior. Epidemiological studies indicate that there are 3 times more boys affected with autism than girls but clinical studies indicate a much higher preponderance in favor of boys. There is an under detection of autism with a late or wrong diagnosis more frequently in girls and women with autism.
OBJECTIVE
To analyze the clinical presentation of autism in girls and women, factors related to under detection and diagnosis or diagnostic confusion, and mechanisms for improving its diagnosis and intervention.
MATERIAL AND METHODS
We will analyze the differences in the clinical presentation of autism between genders, social and cultural factors, cognitive aspects and differential comorbidities in boys and girls with autism, current limitations of diagnostic instruments for the evaluation of autism and which are aspects to improve for a better identification, earlier and more accurate of autism in the female gender.
CONCLUSIONS
Autism in the female gender presents differential clinical, cognitive and biological characteristics associated with under detection and late diagnosis.

Comparative Study
Since Hans Asperger's first description (Arch Psych Nervenkrankh 117:76-136, 1944), through Lorna Wing's translation and definition (Psychol Med 11:115-129, 1981), to its introduction in the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM, 1994), Asperger Syndrome has always aroused huge interest and debate, until vanishing in the DSM fifth edition (2013). The debate regarded its diagnostic validity and its differentiation from high functioning autism (HFA). The present study aimed to examine whether AS differed from HFA in clinical profiles and to analyze the impact of DSM-5's innovation. Differences in cognitive, language, school functioning and comorbidities, were revealed when 80 AS and 70 HFA patients (3-18 years) were compared. Results suggested that an AS empirical distinction within autism spectrum disorder should be clinically useful.

Review
Autism spectrum disorder (referred to here as autism) is one of several overlapping neurodevelopmental conditions that have variable impacts on different individuals. This variability results from dynamic interactions between biological and non-biological risk factors, which result in increasing differentiation between individuals over time. Although this differentiation continues well into adulthood, the infancy period is when the brain and behavior develop rapidly, and when the first signs and symptoms of autism emerge. This review discusses advances in our understanding of the causal pathways leading to autism and overlapping neurodevelopmental conditions. Research is also mapping trajectories of brain and behavioral development for some risk groups, namely later born siblings of children with autism and/or infants referred because of developmental concerns. This knowledge has been useful in improving early identification and establishing the feasibility of targeted interventions for infant risk groups before symptoms arise. However, key knowledge gaps remain, such as the discovery of protective factors (biological or environmental) that may mitigate the impact of risk. Also, the dynamic mechanisms that underlie the associations between risk factors and outcomes need further research. These include the processes of resilience, which may explain why some individuals at risk for autism achieve better than expected outcomes. Bridging these knowledge gaps would help to provide tools for early identification and intervention that reflect dynamic developmental pathways from risk to outcomes.

Randomized Controlled Trial
Sensory processing problems and related dysfunctions are among the most common conditions in children with autism spectrum disorder (ASD). This study examined the effect of sensory integration therapy (SIT) on different aspects of occupational performance in children with ASD. The study was conducted on an intervention group ( n = 16) receiving SIT and a control group ( n = 15) with 3- to 8-year-old children with ASD. The Short Child Occupational Profile (SCOPE) was used to compare the two groups in terms of the changes in their occupational performance and the Sensory Profile (SP) was used to assess sensory problems. The intervention group showed significantly greater improvement in all the SCOPE domains, as well as in all the SP domains, except for the "emotional reactions" and "emotional/social responses" domains, ( p < .05). The effectiveness of SIT in improving occupational performance in children with ASD as a health-related factor is supported by our findings.
