A headache caused by excessive dilation of the arteries in the brain. Symptoms include severe head pain, sensitivity to light (photophobia), occasionally sensitivity to smells, nausea, dizziness, vomiting and/or visual disturbances. See Vascular Headache.
Migraine headaches are long (several hours or days), moderate or severe, and may be throbbing, one-sided or bi-frontal, accompanied by visual symptoms, nausea, weakness on one side of the body, difficulty speaking, and/or sensitivity to light/sound.
The most common type of vascular headache involving abnormal sensitivity of arteries in the brain to various triggers resulting in rapid changes in the artery size due to spasm (constriction). Other arteries in the brain and scalp then open (dilate), and throbbing pain is perceived in the head. The tendency to migraine is inherited and appears to involve serotonin, a chemical in the brain involved in the transmission of nerve impulses that trigger the release of substances in the blood vessels that in turn cause the pain of the migraine. These nerve impulses cause the flashing lights and other sensory phenomena known as an aura that may accompany a migraine . Not all severe headaches are migraines and not all migraines are severe.

A type of headache thought to be related to abnormal sensitivity of blood vessels (arteries) in the brain to various triggers resulting in rapid changes in the artery size due to spasm (constriction). Other arteries in the brain and scalp then open (dilate), and throbbing pain is perceived in the head. The tendency toward migraine appears to involve serotonin, a neurotransmitter that can trigger the release of vasoactive substances in the blood vessels.
Do you know that 15 million Americans suffer from migraine headaches. There are many reasons for migraine headaches. Doctors of Chiropractic have discovered one of the most common reasons is cervical spinal degeneration, a misalignment and straightening of the neck that puts pressure on the nerves and arteries, causing them to swell. With less blood and oxygen reaching the brain a headache develops. By adjusting the cervical vertebra, less pressure is put on the nerves and arteries allowing blood and oxygen to f low to the brain. Most headaches can successfully be treated by a Doctor of Chiropractic through spinal adjustments. If you are a migraine sufferer, consult a Doctor of Chiropractic for evaluation.
