DH flatted with a family friend of a friend in uni. A guy in his mid 20's. I remember him as the introverted weirdo with no friends who had no idea how to behave around others (he'd ignore you completely if you spoke to him, walk into the bathroom while you were showering, didn't close the toilet door and displayed inappropriate 'personal habits' in public - ahem!) He spent all his time on the computer and ate the same foods every day without fail. We heard about two years after that he'd been diagnosed as ASD and his whole life had changed. He had a whole network of friends, had joined a choir, had other hobbies outside the home and was learning social skills. Apparently the change was remarkable and his whole family were stoked they now had a son/brother.
I'd say go for it. In my eyes, it would be similar to finding out you have a food intolerance...you can then adjust your eating habits accordingly and feel heaps better for it.
