Cause of Brain Freeze Revealed
Yahoo ^ | 22 Apr 2012 | Jennifer Welsh

Posted on 04/23/2012 4:04:02 AM PDT by shove_it

Most people have likely experienced brain freeze — the debilitating, instantaneous pain in the temples after eating something frozen — but researchers didn't really understand what causes it, until now.

Previous studies have found that migraine sufferers are actually more likely to get brain freeze than people who don't get migraines. Because of this, the researchers thought the two might share some kind of common mechanism or cause, so they decided to use brain freeze to study migraines.

Headaches like migraines are difficult to study, because they are unpredictable. Researchers aren't able to monitor a whole one from start to finish in the lab. They can give drugs to induce migraines, but those can also have side effects that interfere with the results. Brain freeze can quickly and easily be used to start a headache in the lab, and it also ends quickly, which makes monitoring the entire event easy.

The researchers brought on brain freeze in the lab by having 13 healthy volunteers sip ice water through a straw right up against the roof of their mouth. The volunteers raised their hands when they felt the familiar brain freeze come on, and raised them again once it disappeared.

The researchers monitored the blood flow through their brains using an ultrasoundlike process on the skull. They saw that increased blood flow to the brain through a blood vessel called the anterior cerebral artery, which is located in the middle of the brain behind the eyes. This increase in flow and resulting increase in size in this artery brought on the pain associated with brain freeze.

Why was good money spent on this stupid study?
What moron couldn’t put together the fact that a sinus headache and brain freeze have the same effect on a person?

It is not news that increased blood flow to the brain causes migraines. An old time ‘remedy’ used to prevent or moderate migraines is putting your hands in warm water to divert the blood flow to your hands.

"Caffeine, because it blocks adenosine, has the opposite effects of adenosine. Caffeine constricts blood vessels in the head and neck, and increases the release of excitatory neurochemicals, so increases the rate of nerve firing. That's why caffeine is stimulating.

Caffeine has only one known mechanism of action at likely doses: occupation and blockade of adenosine receptors. Whatever the cause of a given primary or secondary headache, if caffeine relieves that headache, it does so by blocking adenosine. That tells us something important about headaches relieved by caffeine: their causal mechanism involves adenosine binding to adenosine receptors.

The Best Part about a Brain Freeze is how good your head feels AFTER the pain stops. But it don’t last long.

Funny you posted this. I applied numerous times over the past three years to do a study on “The Effect of Incandescent Light Mandatory Usage and the Incidence of Visual Acuity Diminishment From 2013 to 2050.” Nobody got back to me until the third time and I was told in vague terms ‘ Shut up, a..hole. We ain’t interested’. I only asked for $30,000,000. Figured I’d be dead before they asked for it back.

Hey idiot, migraine, sinus headache and brain freeze are all physiologically the result of stimulation of the same nerve bundles. The study is stupid, because the authors should have done their homework and read the older studies from twenty years back, instead of re-inventing the wheel.

Pimping for research dollars. I wonder why this is even a story since we have known for some considerable time that brain freeze is caused by increased blood flow as the body tries to warm the area then the reduction of the flow as the precursor, cooling, diminishes.... the reason brain freeze actually happens after the cold is applied and not when it is applied.

This makes no sense from a thermodynamic standpoint. The flow doesn’t increase due to cold. If anything the blood vessel becomes constricted due to the drop in temperature and the flow of blood staying the same (heart keeps a pumpin) increases the pressure against the vessel wall which then pushes against the surrounding area.

It also explains both the thumb against the roof (someone else noted) which cuts off the flow thus limiting the pressure buildup further up the chain - and the 2nd way I know of which is to place a cold item on your forehead which constricts an adjacent area limiting the impact to the first.

cold increases flow...right

Hadn't heard that one before...I'll have to try that next time I have a migraine. I have meds that work decently enough minimizing a migraine once it's started.

Back in the Navy, the doc told me to pound down a pot of coffee once one started...that seemed to work...sometimes. Only problem with that was when it didn't work, I would be wide awake through the whole migraine hell. Of course I could never sleep through a migraine anyway.

“sinus headache and brain freeze have the same effect on a person?”

Hadn't thought of this but I have had brain freeze and sinus headaches for years. I can control brain freeze by not instigating it with extreme cold but the sinus headache rolls on it's own and I can't predict it.

I do know that caffeine helps with sinus headaches.

So does throwing up (maybe that takes the pressure off of the thing they mentioned). And, yes, I have hurt enough to provoke vomiting.

Caffeine (with pressure on system) works, too.

Had never heard of this; good to know it now so I don't have to vomit to take the pressure off.

Thanks!

Although the study may sound silly to you, it has indeed contributed to our knowledge base about how the brain works.

Having been a life long sufferer of migraines, I appreciate any advance towards finding their cause and a treatment to prevent them. While it’s been long known that migraines are caused by vascular activity, it’s still not known what causes that. Only time and more studies are going to figure it out.

And, BTW, as is often the case, research into one subject can lead to insights into something completely outside the scope of the study. This may be one of those examples.

The only difference I’ve noted is that brain freeze is pretty short.

When ever I get one, the first thing that happens is
I get a shifting band of rainbow light across my vision,

headache but if I do nothing oh my!

Midrin was the best med for me but it was discontinued in 2007. Two of those before lying down and I slept off most of the headache.

That’s what I use...same effect too. 2 pills at onset, and then within an hour I’d be woosey enough to sleep a bit.

Even with that though, I generally feel like crap the rest of the day.

I used to do more than put my hands in warm water. I would sit in a very hot tub of water until my skin, that was under the water, turned bright red. That seemed to help. If it was a tension headache I would float (as much as possible, in a hot tub of water.

Last time I tried to refill it, I was told it is no longer available. No one makes it now because under newer FDA guidelines it doesn’t have proper approval for use and it’s too costly for the drug companies to gain necessary approval for continued sale.
