Migraines: Myth Vs. Reality (Part 1)
January 5th, 2010 . by Peter
MYTH: A MIGRAINE IS JUST A BAD HEADACHE.
REALITY: MIGRAINE IS A DISEASE, A HEADACHE IS ONLY A SYMPTOM. IN ADDITION, THE CAUSE OF MIGRAINE PAIN IS THE OPPOSITE OF THE CAUSE OF HEADACHE PAIN.
Migraine is disease, a headache is only a symptom. Migraine pain is caused by vasodilation in the cranial blood vessels (expansion of the blood vessels), while headache pain is caused by vasoconstriction (narrowing of the blood vessels). During a migraine, inflammation of the tissue surrounding the brain, i.e., neurogenic inflammation, exacerbates the pain. Therefore, medicine often prescribed to treat a headache, such as beta-blockers, dilate the blood vessels and therefore can make a Migraine worse.
