Does sneezing cause brain damage?

Only if you suppress a sneeze instead of just letting it out. Otherwise, not a chance.

Hmm...don't think sneezing would cause brain damage, not a chance. However, if you sneeze too much in the middle of the night, your partner might be woken up and give you a whack over the head, then brain damage is clearly taken place lol!!! Just joking... No, don't think so and never heard of sneezing that causes brain damage. Cheers!

Really? I never heard of that, I always sneeze...

No. There’s no connection between the bit of the respiratory tree that the sneeze has to rush out at 100kph at your brain. I think if you don’t let the sneeze out there’s a possibility you could end up with the mucus it’s trying to dislodge being rammed further into the passages inside the nose, the sinuses for example. You could actually encourage the build-up of mucus which could be laden with infection. You could encourage infection so it’s probably better to let it out. There’s nothing better than a sneeze, is there?

No, it does not cause brain damage, nor does it cause stupidity in people. Were this the case, then there would be an awful lot of psychiatric hospitals being built to hold every last person on this earth. Don't worry about it. :D

Stifling a sneeze, holding your nose, can force bacteria into the back of your sinuses and cause an infection. In very rare cases, this infection could back up into your brain.

Maybe, if you go all headbanger when you sneeze. Don't throttle your head, try to keep it still. If you do have to go all headbanger, please don't drive a car while doing it. If sneezing causes brain damage, that would certainly explain all of the dumb people in the world.
