A cold-stimulus headache , also known as frozen brain , ice cream headache , trigeminal headache or given the scientific name of ganglioneuralgia sphenopalatina (meaning "sphenopalatina ganglion pain "), is a form of shortened pain or headache that is generally associated with consumption (especially rapid consumption) Cold drinks or foods like ice cream and ice appear. This is caused by having something cold touching the roof of the mouth, and is believed to result from a nerve response that causes rapid constriction and swelling of the blood vessels or "refers" the pain from the roof of the mouth to the head. Intake levels for cold foods have been studied as contributing factors. Headaches with cold stimuli differ from dentin hypersensitivity, a type of pain that can occur in similar circumstances.
Cats and other animals have been observed to experience the same reaction when presented with similar stimuli.
The term "ice cream headache" has been used since at least January 31, 1937, contained in journal entries by Rebecca Timbres published in 1939 book We Do not Ask for Utopia: A Quaker Family in Soviet Russia >.

Cause and frequency
Cold-stimulus headaches are a direct result of rapid cooling and capillary warming in the sinuses leading to periods of vasoconstriction and vasodilation. The same but painless vascular response causes the face to appear "reddened" after being out on a cold day. In both cases, the cold temperature causes the capillaries in the sinus to narrow and then undergo extreme rebound widening as they heat up again.
In the ceiling, this widening is felt by nearby pain receptors, which then send signals back to the brain via the trigeminal nerve, one of the main nerves of the face area. These nerves also feel facial pain, so that the brain's neural signals interpret the pain coming from the forehead - the same "referring pain" phenomenon seen in heart attacks. Brains that freeze the brain can last from a few seconds to several minutes. Research shows that the same vascular mechanisms and nerves involved in "brain freezing" cause aura (sensory disturbance) and pulsatile (pulsatile) phases of migraine.
It is possible to suffer from a cold-stimulus headache in hot and cold weather, since the effect depends on the temperature of the food consumed rather than the environment. Other causes that may mimic the sensation of a cold-burning stimulus include those generated when high speed drilling is done through the inner table of the skull on the person undergoing the procedure in a wakeful or anesthetized state.

anterior artery cerebral theory
Another theory that causes the cold-stimulus headache is explained by increased blood flow to the brain through the anterior cerebral artery, which supplies oxygenated blood to most of the medial part of the frontal lobe and the superior medial parietal lobes. Increased blood volume and increased size in these arteries are thought to lead to pain associated with cold-pressure stimulus.
When the anterior cerebral artery constricts, resisting the response to this increase in blood volume, the pain disappears. Widening, then constricting quickly, from these blood vessels can be a kind of self-defense for the brain.
This blood stream can not be cleaned as soon as it comes during a cold-stimulus headache, so that blood flow can increase the pressure inside the skull and induce such pain. Because the intracranial pressure and temperature in the brain increase the blood vessel contract, and the pressure in the brain decreases before it reaches dangerous levels.
Relief
To relieve pain, some doctors recommend pressing the tongue to the roof of the mouth to warm the area, tilting the head back for 20 seconds, or drinking something warmer than anything that causes headaches. Some people report the relief of breathing through the mouth and out through the nose, thereby passing the warm air through the nasal passages.
Research
This phenomenon is quite common to be the subject of research published in the British Medical Journal and Scientific American . A study conducted by Maya Kaczorowski showed a higher incidence of sphenopalatina ganglioneuralgia in subjects who consumed ice cream samples in less than 30 seconds compared to those who consumed slowly, indefinitely (27.3% and 12.5% ​​respectively -masing). However, Kaczorowski in the end can not draw a clear connection between the speed of consumption and the incidence of sphenopalatina ganglioneuralgia.
According to a study by Nigel Bird, Anne MacGregor, and Marcia I. Wilkinson published in the Headaches journal, in their study "17% of migraine patients and 46% of students had headaches after palatal application or ingestion of ice cream. "
