The Main Symptoms of Autism in Adults

Autism in Adults

Autism is a developmental and neurological condition that affects an individual’s behavior, socialization, and communication skills. Usually, it is identified by the time a child turns three years old. 

However, autism is a spectrum disorder, which means that individuals with it may present with symptoms that range from mild to severe. Individuals with mild symptoms may make it into adulthood without receiving a comprehensive diagnosis because they managed to mask their symptoms growing up. In other instances, a lack of support or awareness around their symptoms might have meant they never received a diagnosis. 

As awareness about autism increases, a larger number of adults identify autistic symptoms in themselves and push for a diagnosis. Women, especially, are more likely to receive a later diagnosis of autism than men. This is partly due to high functioning women with autism hiding their symptoms and forcing themselves to fit in socially. There is also growing research to suggest that autism may present differently in males and females, meaning women are much less likely to have received an early diagnosis. 

Helping adults receive a correct diagnosis is important. Many would have struggled with autistic symptoms all their lives, and a diagnosis can really help many adults come to terms with their own behavior and reaction to situations. It also enables them to connect with others in the same situation and receive support with their symptoms and diagnosis.

What next?

If you can identify more than one or two of the above symptoms in yourself, you might want to talk to a medical professional about exploring the options to be evaluated for autism. There are currently no standard diagnostic tests for adults with suspected autism, but diagnostic assessment guides for those working with adults with autism. 

Receiving a correct diagnosis is important at any age.
