He can't lead any kind of normal life, no amount of professional help or supervision will change that, he doesn't have any rational experience of the world around him. His usual day is filled with running around the room, bumping into walls while screaming. As he becomes an adult, he more frequently needs to be tied down to the bed (done by professional psychiatrists at a hospital). He never has a moment of lucidity, you can't talk to him about anything; he understands speech and can talk, but it's phrases like "NEED PEE NOOOOOOOOOW" screamed at the top of his lungs, and not much else. Then you need to drag him there while he fights you, he doesn't understand you're trying to fulfill his request. The more pressing the matter, the more will he fight everything and everyone around; of course that also means that the pee or feces usually end up outside the toilet, so he's wearing a diaper. He has preferences for toys and children's cartoons, but the only way he makes others aware of that is that it calms him down, he never said something such as "I like X" and from brain imaging results the doctors don't think he has thoughts like that, as his brain is permanently so overstimulated he's constantly in flight-or-fight instinctive mode. Which is good, actually - it means that if this overstimulation could be somehow lessened, he actually might become capable of having something resembling a normal life. So, the help I said he needs is the researchers to keep looking for ways to decrease the impact of his autism, instead of listening to people saying stuff like "autism doesn't need to be cured".
