The “ice cream headache” book its mysteries

The headache caused by cold (also referred to as “ice cream”) is an experience that most of us have known: a pain in the head usually in the front following the ingestion of ice or a too cold soda. Despite its high frequency, scientists are still struggling to explain the disorder. The explanation of this phenomenon could eventually have an impact on the treatment of other forms of migraine.

American researchers recruited 13 adults in good health and have monitored the blood flow of volunteers at the level of the cerebral arteries using several trans-crannies Doppler. All drank of the water ice with a straw pressed against their Palace (ideal conditions to bring this famous “ice cream headache”) and then drank the same amount of water at room temperature.

Volunteers raised their hands at the onset of pain and his disappearance. The results showed that a particular artery, anterior cerebral artery, to dilatants quickly and was inundated with blood at the time where the pain was felt. Soon after this expansion, the same vessel contracts as the discomfort.

Dr Serrador team think that dilation followed by rapid constriction may be a system of self-defense of the brain: “the brain is one of the very organs of the Organization, and he needs to operate permanently.” It is relatively sensitive to temperature, so vasodilatation may bring hot blood within the fabric to ensure that the brain is still hot”.” But because the skull is a closed structure, researchers believe that this sudden influx of blood could increase the pressure and thus induce pain. Vasoconstriction following would be a way of lowering the pressure in the brain until it reaches dangerous levels.

According to him, similar changes in blood flow may be at work in different types of migraine, headache post-traumatic stress and other headaches. If further research confirms these suspicions, it could pave the way for other treatment of migraine. Drugs that would block the vasodilatation or targeting channels specifically involved in vasodilatation associated headaches tomorrow could bring relief to migraine. France, 10-12% of the population (but 15 to 18% of women) suffering from migraines and 2-3% are victims of tension headache.
