Migraine Headaches

Close to 30 million people across the US have experienced a migraine headache, and about 75 percent of them are women. The majority of these people fall between the ages of 15 and 55, and migraines run in many of their families. Since migraines are frequently misdiagnosed as a sinus or tension headache, not even half of people suffering from migraines receive the proper treatment.

Risk factors

There are numerous risk factors that can spark a migraine including:

Inconsistent sleep patterns.
Postponing a meal or skipping it entirely.
Taking medication that results in swollen blood vessels.
Everyday or almost daily intake of pain killers designed to fight headaches.
Bright lights (e.g., sunlight, florescent lights).
Motion pictures.
Specific food.
Loud racket.

People with high amounts of stress or who may be battling depression are also more susceptible to migraines, but these conditions can easily be treated.

Symptoms

Symptoms associated with migraines include:

Pulsating pain generally located on one side of the head.
Mild to severe pain impacting daily affairs.
Upset stomach.
Sensitivity to intense light or noise.
Headaches lasting three consecutive days or more.
Vision problems or aura.
Intensified pain during strenuous activity.

Around 20 percent of people with migraines will experience aura before the onset of the pain. This means people's vision will be interrupted by wavy lines, dots, or blinking lights. There may also be between 20 and 60 minutes of blind spots before the migraine begins. Some migraine sufferers may notice a numb, tingly feeling in their arm or face or find it hard to speak. At one time, it was believed that aura was caused by the narrowing of small arteries carrying blood to parts of the brain. In reality, it is a result of the transient changes in nerve cell activity.

The pain brought about by a migraine occurs when excited brain cells prompt the trigeminal nerve to produce chemicals that aggravate blood vessels on the brain's surface and cause them to become inflamed. Then, the swollen blood vessels shoot messages of pain to the brainstem, where those signals are processed. Migraine pain is usually confined to the eye or temple regions, but it may also have a presence in the face, sinuses, jaw, or neck. When the attack is full-fledged, the head becomes overly sensitive to any type of touch. Even combing hair or shaving may pose a problem.

A physician will attempt to diagnose a migraine based on the patient's history of unique migraine symptoms, any additional headache attributes, and the history of migraines in the family bloodline. This assessment will not uncover any organic causes of the headache. At this time, no tests exist to confirm the diagnosis of a migraine.
