Last night my son was eating an ice cream bar and got a "brain freeze" and seemed to pass out for a couple seconds. what would cause this?

Well: An ice cream headache is the direct result of the rapid cooling and rewarming of the capillaries in the sinuses. This causes a painful stimulus that is short lived and felt as a headache. The pain associated with it can cause the passing out by a mechanism referred to as vaso vagal. Read. http://en.wikipedia.org/wiki/vasovagal_response.

Two thoughts: "brain freeze" is often associated with people who are susceptible to migraine, and if he did "pass out", he may have basilar migraine variant, but also, might wonder about an epileptic event. Worthwhile to see your doctor, just to be safe. But most likely, merely an episode of syncope due to a vaso-vagal reaction.
