I know there is a name for my sister's dropping things when she laughs really hard
I can make my sister laugh really easily- sometimes by just not saying anything and just giving her a look. The same thing with my youngest daughter.
They both have this syndrome where laughing hysterically causes them to drop things and appear to be paralyzed. I saw a reference to this somewhere and should have written it down. I remember that it is pretty common.
Does she pass out? If so, that would be cataplexy, which is related to narcolepsy. I don't know how common it is but I have a friend with it. There is some sort of treatment but not sure what. Sorry! Google it and you will find some more info.
