Autism is a wide spectrum. Some would consider ADHD part if it. If nothing else, there is lots of overlap.
Asperger’s is just a tad bit more on the socially awkward side: inability to understand social cues being a big one. I learned to fake it and it took me a long time to develop genuine empathy in situations demanding raw emotion. I’m still awkward sometimes - unsure of what the socially acceptable response is in a situation.
This is in sharp contrast to my spouse who is also ADHD. She is more easily distracted and has higher dysfunction. Yet, she is socially more aware and talking to people is second nature to her.
