Autism in adults, especially Autism in adult women, is not as well understood as Autism in children. Knowledge varies a lot depending on the clinician.
Your friend should try and find a clinician with knowledge and experience in assessing women. These people are sometimes hard to find.
Autism and ADHD are common co-occurring conditions. This is unofficially known as AuDHD. We have a thread about living with AuDHD. She might be interested in taking a look at it to see if she relates to what is being described.

“My autism is not a superpower. It also isn’t some kind of god-forsaken, endless fountain of suffering inflicted on my family. It’s just part of who I am as a person”. - Sara Luterman
