Migraine is a neurological condition that can cause multiple symptoms. It's frequently characterized by intense, debilitating headaches. The precise causes and mechanisms of migraine are unknown. Attacks originate with chemical changes in the brain and nervous system and progress into painful restrictions in blood flow. Changes in the brainstem and its interactions with the trigeminal nerve, a major pain pathway, might be involved. So might imbalances in brain chemicals — including serotonin, which helps regulate pain in your nervous system. Researchers are studying the role of serotonin in migraines. Other neurotransmitters play a role in the pain of migraine, including calcitonin gene-related peptide (CGRP).Certain tastes, odours, lights, noises, and physical or emotional stress may trigger migraine. Medications usually include pain killers and migraine preventive medicines.

Benefits of HBOT :

Persons who may benefit from hyperbaric oxygen therapy (HBOT) are those whose migraines have more of a vascular origin (induced either by imbalance of chemicals or abnormal blood flow to a particular brain area) or those who have side effects or contraindications to standard drug therapy. Hyperbaric oxygen therapy for migraines aims to minimize or eliminate symptoms and decrease the frequency at which they occur, without the use of prescription drugs. HBOT causes the constriction of blood vessels in the body (the body’s protective response to increased oxygen). HBOT delivered at the time of acute migraine can help by constricting the dilated blood vessels that result in a pulsing sensation seen in migraine. In fact, increased oxygen is actually the primary treatment for cluster headaches. Dr. Harch’s research shows that if a migraine headache is the result of an injury to the brain (traumatic brain injury, toxic brain injury, etc.), the resultant headaches are one of the most responsive symptoms to HBOT. HBOT has been shown to change the amount of blood flow in the brain during migraine episodes. Additionally, HBOT can favourably alter some of the chemical levels that induce migraines (serotonin and substance P). Both published and unpublished studies show that HBOT is effective in aborting a migraine headache in 80% of patients within 40 minutes of treatment. Studies on HBOT in migraine or cluster headache have shown that there is some evidence for HBOT in acute migraine and supplemental oxygen in cluster headache.
