These are some ideas doctors have for possible triggers of migraine headaches but the specific causes remain elusive. It is believed that vascular changes in the brain are responsible for the pain. Researchers have noted blood vessel contraction and dilations in the brain just prior to migraine occurrence. There are four phases involved with a migraine: prodrome, aura, headache and postdrome.
Prodrome - most migraines are preceded by a phase which may cause depression, food cravings, neck stiffness, nausea, hyperactivity or fatigue in the days preceding the actual headache.
Aura - This is a collection of neurological symptoms that usually involve a person's visual experience. Flashing or wavy lights, strange smells, tingling sensations and cognitive difficulties. Only about 20% of patients with migraines experience aura symptoms.
Headache - Moderate to intense pain with a pulsating quality that lasts 4-72 hours. May be aggravated by loud noise or bright lights. Nausea or vomiting, depression/anxiety, hot flashes and chills, dizziness, confusion, dehydration or fluid retention.
Postdrome - Pain has usually subsided by this point but sometimes a person may experience lasting depression, fatigue or poor concentration.
Migraines tend to respond well to peace and quiet. Many studies have shown that chiropractic is a very effective tool to treat migraines. Sometimes it is immediate relief but most cases require ongoing care to manage painful episodes.
