What Causes Asperger’s Syndrome?

Asperger’s Syndrome, also known as Asperger’s Disorder, is a neurodevelopmental disorder that affects social interaction, communication, and behavior. This condition is part of a group of conditions referred to as Autism Spectrum Disorder (ASD). In this article, we will discuss the various factors that contribute to the development of Asperger’s Syndrome.

Genetic Factors

There is a significant genetic component to the development of Asperger’s Syndrome. Studies have shown that the disorder tends to run in families. A child with an older sibling or parent with Asperger’s Syndrome is more likely to develop the condition.

Researchers have identified several genes that may contribute to Asperger’s Syndrome, although the exact genetic mechanisms still need to be determined. Some of these genes are involved in brain development and function, particularly in the areas of social communication and emotional regulation.

Environmental Factors

Environmental factors may also play a role in the development of Asperger’s Syndrome. There is some evidence to suggest that exposure to pollutants or toxins during pregnancy or early childhood may increase the risk of developing the disorder.

Maternal infections during pregnancy have also been linked to an increased risk of autism spectrum disorders, including Asperger’s Syndrome. Studies have found that children born to mothers who had a flu or other infection during pregnancy are more likely to be diagnosed with ASD.

Brain Development

Asperger’s Syndrome is a result of differences in brain development and function. Studies have found structural and functional differences in the brains of individuals with Asperger’s Syndrome compared to those without the disorder.

Research has shown that the connections between different regions of the brain are altered in individuals with Asperger’s Syndrome. This can affect social and communication skills, language development, and emotional regulation.

Parenting Style

There is no evidence to suggest that parenting style causes Asperger’s Syndrome. However, the way parents interact with their children may affect the child’s social and communication development.

Studies have shown that parents of children with Asperger’s Syndrome tend to show less affection and warmth towards their children. This is not necessarily a cause of the disorder, but it may contribute to difficulties with social interaction and emotional regulation.


While the exact causes of Asperger’s Syndrome are not yet fully understood, research suggests that a combination of genetic and environmental factors contribute to its development. Understanding these factors can help us identify individuals who may be at risk and provide early interventions to improve outcomes.

It is important to note that individuals with Asperger’s Syndrome can lead fulfilling and productive lives with appropriate support and accommodations. This includes interventions such as speech and language therapy, social skills training, and behavioral therapy.

Further research is needed to better understand the causes of Asperger’s Syndrome and develop effective treatments for individuals with the disorder. With ongoing research and support, individuals with Asperger’s Syndrome can achieve their full potential and thrive in their communities.


FAQs about What Causes Aspergers Syndrome

1. Is Aspergers Syndrome a genetic disorder?

Yes, studies have shown that Aspergers Syndrome is largely genetic. This means that a person is more likely to develop Aspergers if they have close family members who also have the disorder. However, genetics alone do not fully account for the development of Aspergers, and environmental factors may also play a role.

2. Can environmental factors trigger Aspergers Syndrome?

There is some evidence to suggest that environmental factors, such as exposure to toxins or infections during pregnancy, may contribute to the development of Aspergers. However, research on this topic is still ongoing, and the exact relationship between environmental factors and Aspergers is not yet fully understood.

3. How can Aspergers Syndrome be diagnosed?

Aspergers Syndrome is typically diagnosed through a combination of clinical assessment and observation of a person’s behaviour and development. There is currently no single test or biomarker that can definitively diagnose Aspergers, and diagnosis can be a complicated process. However, early detection and diagnosis are important in order to provide early interventions and support for people with the disorder.
