Research into autism causes – including genetic and environmental interactions
Research into the genetic and environmental factors and causes that contribute to autism is crucial for better understanding its origins and development.Â
Early diagnosis and screening
Early identification of autism is key to providing effective interventions. The Hospital Research Foundation Group supports research into how autism develops in children, giving hope to many Australian families facing this challenge. Associate Professor Quenten Schwarz, from the University of South Australia is exploring how a particular type of neuron (a specialised cell communicating nerve impulses) becomes deficient in the brain of autistic and schizophrenic patients, with the hope to provide new ways to diagnose, predict and treat these conditions.
Neurodiversity-affirming interventions
The Hospital Research Foundation Group funds research that supports new therapies and approaches for managing autism, aiming to create more inclusive educational and healthcare environments for people living with autism. For example, we are supporting Murdoch University’s Associate Professor Timothy Fairchild’s project, developing an eight-week personalised exercise program and educational resources for families to boost physical activity for children on the autism spectrum.
Innovative therapies
Advancing therapeutic approaches for people on the autism spectrum is a central area of focus in autism research. . Through our partnerships with leading research centres, we support the development and testing of new therapies designed to enhance the quality of life for people with autism.
Associate Professor Timothy Fairchild from Murdoch University is driving research to help children on the autism spectrum with his innovative program aimed at increasing physical activity. Research has shown that children with autism often face barriers to engaging in physical activity, impacting both their physical and mental health. A/Prof Fairchild’s program aims to help make exercise more accessible, with a focus on improving social skills, motor abilities, and emotional wellbeing.

FAQs
Autism Spectrum Disorders (ASD) is an umbrella term used to describe a range of neurodevelopmental conditions characterised by:
- challenges in social communication,Â
- restricted interests, andÂ
- repetitive behaviours.
The term “spectrum” highlights the wide variability in how these traits are expressed, with individuals experiencing different combinations and degrees of severity. In Australia, ASD is recognised as a lifelong condition, affecting individuals across all demographics.
The diagnosis of ASD in Australia is made based on the criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). These criteria focus on two core areas:
- Social Communication and Interaction: Challenges in understanding and engaging in social interactions, including difficulties in maintaining conversations, reading non-verbal cues, and forming relationships.
- Restricted and Repetitive Behaviours: These may include repetitive movements, rigid routines, intense focus on specific interests, and sensory sensitivities.
ASD is called a “spectrum” because it encompasses a wide range of characteristics and severities, meaning individuals can experience very different strengths and challenges. Some may have mild symptoms and be able to live independently, while others may need significant support with daily activities and communication.
The core features of ASD—difficulties with social communication, restricted interests, and repetitive behaviours—can vary greatly in how they manifest. For example, one individual might have advanced verbal skills but struggle with understanding social cues, while another might have limited verbal communication but excel in certain areas like mathematics or art. Sensory sensitivities are also common, but they can range from mild to overwhelming, with some individuals being highly sensitive to sounds, lights, or textures, while others may seek out certain sensory experiences.
This variability is why ASD is considered a spectrum, emphasising that there is no “one-size-fits-all” experience. Each person with autism has a unique combination of abilities and needs.
The exact causes of autism are not fully understood, but research suggests that autism results from a combination of genetic and environmental factors.
While the causes of autism remain complex, research continues to shed light on the multiple factors involved. Both genetic and environmental influences play a role, and ongoing studies aim to improve our understanding, leading to better early interventions and support for individuals with autism.
Genetic Factors
Genetics plays a major role in the development of ASD. Studies have shown that autism tends to run in families, and certain genetic mutations and chromosomal variations have been linked to an increased risk. However, no single gene causes autism—rather, multiple genetic factors interact with environmental influences (Eapen et al., 2013; Hallmayer et al., 2011).
Environmental Factors
Environmental factors, such as advanced parental age, maternal infections, and pregnancy-related conditions, may increase the risk of autism. Studies in Australia have suggested a potential link between prenatal exposure to certain environmental toxins—such as air pollution and pesticides—and an increased likelihood of autism, although further research is needed to establish definitive causal links (Liew et al., 2015; Croen et al., 2011). Maternal health conditions, such as diabetes or obesity, have also been associated with higher risks of ASD, reinforcing the importance of early prenatal care.
Brain Development
Research consistently shows differences in brain structure and function in individuals with autism. These differences may contribute to challenges with social communication and sensory processing. In particular, some Australian studies have identified atypical patterns in brain growth, with rapid brain expansion observed in early childhood among children with autism (Harada et al., 2014). These early developmental differences could influence the core symptoms of autism, including difficulties with language, behaviour, and emotional regulation.
Genetic and Environmental Interaction
The combined influence of genetic and environmental factors on brain development is a key area of ongoing autism research. Australian studies are exploring how genetic vulnerabilities might interact with prenatal or early childhood exposures to increase the likelihood of autism, offering new insights into early diagnosis and intervention strategies.
There is no scientific evidence to support a link between vaccines and autism. Research into vaccinations and autism links has been conducted over several decades has consistently shown that vaccines, including the MMR (measles, mumps, rubella) vaccine, do not cause autism. The misconception that vaccines are linked to autism originated from a now-debunked study published in 1998 by Andrew Wakefield, which was later retracted due to serious methodological flaws and ethical concerns. Since then, numerous large-scale studies and reviews have conclusively disproven any connection between vaccines and autism.
Numerous large-scale studies have thoroughly investigated the potential link between vaccines and autism. For example, a study published in 2002 in The New England Journal of Medicine examined over 500,000 children and found no increased risk of autism from the MMR vaccine (DeStefano et al., 2004). Another study conducted in Denmark involving over 650,000 children found no increased risk of autism after receiving the MMR vaccine (Madsen et al., 2002).
Health organisations worldwide, including the World Health Organization (WHO), and the Australian Department of Health, have all confirmed that vaccines are safe and do not cause autism. These organisations continue to recommend vaccination as essential for preventing serious diseases and protecting public health.
Australian studies have highlighted that there is no correlation between the timing of vaccinations and the onset of autism symptoms (Eapen et al., 2013). Research also emphasises that early brain development, genetic mutations, and other environmental factors may play a role in the onset of autism, but vaccines are not among them. Vaccination remains a safe and vital public health measure that plays a key role in preventing disease and protecting vulnerable populations, including children with autism.
Stem cell therapy is an exciting area of autism research, exploring how stem cells might help address the neurological challenges of Autism Spectrum Disorder (ASD). Stem cell therapy holds promise for autism treatment, particularly in addressing brain development and immune system function. However, much more research is needed in this area.
Stem cell therapy uses undifferentiated cells that can develop into specialised cells to potentially repair brain tissue, promote neurogenesis (new neuron growth), and treat underlying aspects of ASD. Scientists are exploring how stem cells might restore brain function and help manage the core symptoms of autism, such as social communication and sensory processing difficulties.
Stem cell research in autism is still experimental. While the potential is great, challenges include the need for more research on safety, efficacy, and ethical concerns, such as the source of stem cells and long-term effects. Rigorous clinical trials are required before stem cell therapies can be widely used.
