For what it's worth, this sounds like the opposite of autism to me.

People with autism generally have less of a filter for familiar or ignorable stimuli. Where neurotypical people are generally able to tune out things they know or decide to not be relevant, people with autism have less ability to do that, and doing it is more draining for them.

If anything, it sounds more like ADHD to me. But armchair diagnosis is always fraught with peril, and the couple of dozen labels in the DSM-V are nowhere near enough to describe the millions of ways that brains can be different.
