I haven't seen any information relating to holding a sneeze and killing brain cells by doing so. However, a sneeze is your body's way of trying to get rid of an irritant as in the form of Allergies, or a cold or flu virus. Holding a sneeze is not a good idea as whatever irritant sitting inside your nose will not be evacuated and may get into the sinuses and other airways and cause infection.
