I wonder if with the very successful "stars", the lack of solitude could seriously screw you up. They're on the go practically 24/7, little sleep, with the same people, but also masses of others that change at each venue. Drink, weed, & no doubt easy access to coke to cope with it all. Most neuro divergent folk (and non of course) need a lot of solitude and down time to make sense of and navigate a noisy & chaotic environment. Also craving adulation must do a number on your emotional state at some point, especially when it dries up.
