Autism spectrum disorder (ASD) is a complicated neurodevelopmental illness that impacts people differently. While much attention has been given to autism in children, it’s equally important to understand how it manifests in adults. In this blog, we’ll delve into the causes, genetic factors, and different types of autism in adults.

What Causes Autism in Adults?

The exact cause of autism remains elusive, but research suggests a combination of genetic and environmental factors contribute to its development. While some cases may be linked to specific genetic mutations or abnormalities, others may result from prenatal factors such as maternal infections or complications during pregnancy. Additionally, environmental factors like exposure to certain toxins or pollutants may also play a role in the development of autism.

Is Autism Genetic?

Genetics is believed to play a significant role in autism. Studies have shown that individuals with a family history of autism are more likely to have the condition themselves, indicating a strong genetic component. However, autism is considered a complex disorder, meaning it’s influenced by multiple genes rather than being solely determined by one gene. This complexity makes it challenging to pinpoint specific genetic causes, but ongoing research continues to shed light on the genetic basis of autism.

Types of Autism in Adults:

High-Functioning Autism (HFA):

Individuals with HFA often have average or above-average intelligence.

They may struggle with social interactions and communication but exhibit fewer severe symptoms compared to other forms of autism.

Asperger’s Syndrome:

Asperger’s syndrome is characterized by difficulties in social interaction and nonverbal communication.

Individuals with Asperger’s often have intense interests in specific subjects and may exhibit repetitive behaviors.

Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS):

PDD-NOS is a diagnosis given when an individual exhibits some, but not all, of the symptoms of autism.

Symptoms may vary widely in severity and presentation, making diagnosis and treatment challenging.


Autism in adults presents unique challenges and opportunities for understanding and support. By exploring the causes, genetic factors, and different types of autism, we can gain a deeper appreciation for the diversity within the autism spectrum and work towards creating more inclusive and supportive environments for individuals with autism. Ongoing research into the underlying mechanisms of autism will continue to enhance our understanding and improve interventions for adults living with this condition. e
