I was just wondering if anyone has experienced uncontrollable laughter for no apparent reason in their child. My son will go into hysterical laughter, sometimes in the middle of the night, and when this happens he cannot feel pain or even stand up by himself he becomes "limp". I've just mentioned this to his neuro and he seems concerned. I always just thought it was related to his autism. Any ideas?
BTW, my son has not been dx w TSC, but I have and very recently so I am not familiar with all of the "symptoms" yet.
