Many causes of migraines are not known.  Sometimes they run in families, and in many case migraines can go back for several generations.  Migraines may be caused by changes in the trigeminal nerve, a major pain pathway.  Imbalances in brain chemicals, including serotonin — which helps regulate pain in your nervous system — also may be involved. Serotonin levels drop during migraines.  This may trigger your trigeminal system to release substances called neuropathies which travel to your brain's outer covering (meninges). The result is headache pain.

Most common types of headaches: Migraine, tension headache, sinus headache, and mixed headaches.  Cluster headaches are another type which cluster in bunches during certain times.

Triggers: Triggers are something that will bring on a headaches or migraine.  This can includes certain foods, changes in a woman’ menstrual cycle, certain sensory stimuli like flashing lights or motion, changes in weather, or sensitivity to the cold in winter or hot weather.  There are many possible triggers, but usually the person knows what they are.  A common treatment is to reduce the possibility of triggers.

Hormonal changes in women. Fluctuations in estrogen seem to trigger headaches in many women with known migraines. Women with a history of migraines often report headaches immediately before or during their periods, when they have a major drop in estrogen. Others have an increased tendency to develop migraines during pregnancy or menopause. Hormonal medications — such as oral contraceptives and hormone replacement therapy — also may worsen migraines, though some women find it's beneficial to take them.

Foods. Some migraines appear to be triggered by certain foods. Common offenders include alcohol, especially beer and red wine; aged cheeses; chocolate; aspartame; overuse of caffeine; monosodium glutamate — a key ingredient in some Asian foods; salty foods; and processed foods. Skipping meals or fasting also can trigger migraines.

Stress. Stress at work or home can instigate migraines.

Sensory stimuli. Bright lights and sun glare can produce migraines, as can loud sounds. Unusual smells — including pleasant scents, such as perfume, and unpleasant odors, such as paint thinner and secondhand smoke, can also trigger migraines.

Changes in wake-sleep pattern. Either missing sleep or getting too much sleep may serve as a trigger for migraine attacks in some individuals, as can jet lag.

Physical factors. Intense physical exertion, including sexual activity, may provoke migraines.

Changes in the environment. A change of weather or barometric pressure can prompt a migraine.

Medications. Certain medications can aggravate migraines.  At a later time we will include such a list.
