22 Symptoms and Signs of High-Functioning Autism In Adults (2022)

Contrary to what most people think, this is not just found in children, signs of high-functioning autism in adults is also quite common.

What Does High Functioning Autism In Adults Mean?

It depends. If someone falls in Level 1 of ASD, then they are considered to be high functioning. However, sometimes it might be that someone’s behavioral attitudes might be Level 2, and their social capabilities turn out to be Level 1.

There are several factors that lead to an autistic person being labeled as high functioning, and some of the factors are as follows:

  • How they communicate with others.
  • How well they’re doing at their jobs and whether they are being able to sustain it or not.
  • How they handle themselves in social situations.
  • How they build and maintain their personal relationships.
  • How they try to mask or hide their autistic traits.

The bottom line is that the better a person is able to mingle in a neurotypical society, the higher functioning they will be. Due to this reason alone, many autistic people don’t get diagnosed until quite later in their lives.
