The association between maternal diabetes and risk of autism spectrum disorder in offspring was not completely consistent. We performed an updated and systematic review and meta-analysis with relevant studies published until 6 August 2020. We included 17 publications, describing 15 studies, including 1,751,537 participants. Exposure to maternal…

Autism spectrum disorder (ASD) is a complex neurodevelopmental condition. Genetic, environmental, and epigenetic variables are all likely to have a role in the occurrence of ASD. This systematic review was done to determine the implications of genetic factors and modifiers in ASD. Our results show that nearly all human chromosomes have one or more…

Gelotophobia (fear of being laughed at) is an under-researched phenomenon in autistic people, yet can have a significant impact on autistic people's quality of life. A narrative review was undertaken to explore if gelotophobia and being autistic are related and what is currently known in the academic literature regarding gelotophilia (joy of being…

Motor stereotypy is a type of repetitive motor behavior frequently occurring in autism spectrum disorder (ASD). Individuals with maladaptive daydreaming (MD) report repetitive motor behavior associated with addictive and immersive daydreaming. Many autistic self-advocates report symptoms of MD. Motor stereotypy in ASD is associated with lower…

We conducted meta-analysis in order to determine if there are significant differences in left and right amygdala volume in individuals with autism spectrum disorders (ASD) compared to a control group. Twenty-three studies fulfilled inclusion criteria for our study. Right amygdala volume was significantly larger in ASD patients compared to controls…

This study aimed to review the scientific literature on etiopathogenic factors of savant syndrome associated with autism spectrum disorder (ASD). Searches were performed in the following databases: Medical Literature Analysis and Retrieval System Online, Embase, Scopus, Science Direct, Cochrane Library, Latin America and Caribbean Center on Health…

In the last 5 years, the literature on animal-assisted intervention (AAI) for Autism Spectrum Disorder (ASD) has doubled in size from 42 studies prior to 2015 to 85 studies (cumulative total assessed in 2020). Horses remain the most commonly researched animal for AAI, followed by dogs. The most commonly researched outcome was social interaction,…

Sibling-mediated interventions (SMI) have the potential to increase social communication, play, and interpersonal skills for children on the autism spectrum. However, less is known about effective practices for training siblings to be intervention mediators. Existing SMI systematic reviews and meta-analyses have focused on the effects of SMIs for…

Background: Gender dysphoria (GD) appears disproportionately common in people with autism spectrum disorders (ASDs). Concurrent intellectual disability (ID) may limit assessment of these individuals and their access to gender-affirming healthcare. This study aims to summarise knowledge on the presentation of GD in those with co-occurring ASD and…

Autism spectrum disorder (ASD) can affect individuals from different backgrounds, cultures, and heritages. Many cultural factors may change the individuals' ASD experience in daily life. It also impacts how autism is tackled, interpreted, and acknowledged in various communities. Cultural perceptions about ASD and other disabilities may prevent…

Although anxiety is commonly researched in autism, the focus has predominantly been on anxiety disorders and not upon general levels of anxiousness or trait anxiety. This review summarises research investigating trait anxiety in autism. Systematic searches yielded 1099 records, with 23 studies meeting inclusion criteria. Study participants were…

Multiple technological aids have been proposed to support the social interactions of people with autism. The literature is extensive, but in many of the works there is a lack of clear processes focused on improving social skills. In this paper, we analyse a selection of 57 technological supports from the last 10 years, whose main characteristic is…

Friendships are vital to mental health and well-being. Understanding autistic individuals' lived experiences of friendship is necessary to support friendship development. A scoping review exploring autistic individuals' experiences of friendship was undertaken to understand their perspectives of friendship. Electronic database and manual reference…

The relationships between neurotypical (NT) children and their sibling with autism spectrum disorder (ASD) can be complex and lead to stress and strained relationships. Existing theories help us understand the relationships of children with ASD and their caregivers, but we have limited knowledge about the experiences of NT siblings. To fill this…

Sleep disturbances have been found to increase severity of core autism spectrum disorder (ASD) symptoms such as social and communication difficulties and repetitive behaviours. However, very little is known about the impact of sleep on cognitive functioning in ASD. A systematic literature search identified fifteen original studies meeting…
