Migraine headaches are a type of hereditary headache. There have been several theories as to what physically triggers a migraine headache. Some theories state that temporary constriction of the blood vessels in the brain are the culprit. Other theories blame very complex neurovascular events where studies using MRI (magnetic resonance imaging) have shown areas of increased excitability in the brain. Others blame the release of certain neurological chemicals or dysfunction of the trigeminal nerve.
Symptoms of Migraines
Some sufferers of migraine headache report and aura immediately preceding the symptoms of their migraine headaches. An aura is a physical warning that a migraine headache is about to occur. Types of auras that have been reported include the sensation of a ringing in the ears, strange odors, changes in taste, flashing lights, seeing halos, blind spots in the visual field or temporary vision loss. Symptoms of migraine include severe headache with sensitivity or light, sound or smell, nausea and or vomiting, fatigue, dizziness, loss of appetite or blurry vision.
Treating Migraines or Treatment of Migraines
Several medications are used to treat the symptoms of migraine. The ultimate goal of migraine treatment is to avoid specific migraine triggers for the individual patient. In addition, many migraine sufferers have found relief from their migraine headaches and in the frequency of their occurrence through the use of hyperbaric oxygen therapy (HBOT). The high levels of oxygen delivery offered by HBOT have been shown to abort a migraine in progress. In addition, hyperbaric therapy stimulates the growth of new blood vessels (angiogenesis). This provides a permanent increase in blood flow and oxygen delivery to vital tissues in the brain decreasing frequency of the migraines.
