About Autism
High functioning autism

Autism exists on a spectrum.

Some people will experience certain symptoms in a certain way while others will not and vice versa.

This has led to a term in the community known as “high functioning autism.”

But what exactly does this mean, and how is it identified and diagnosed?

What is High Functioning Autism?

High functioning autism is not an official medical diagnosis.

Instead, it’s an informal term used to describe individuals with autism who are able to speak, write, read, and handle basic everyday tasks.

These people can live independently and hold down jobs with minimal interruptions to their daily lives.
