A friend of mine asked me, what is the cause of migraine headaches? Well, I am curious myself so I did a little research on migraine and "copy & paste" the information that I have (plagiarism at its best..hehe). No worries, I'll cite the sources ;).
What are migraine headaches?Migraines are disabling headaches that most likely stem from problems with the nerves and blood vessels in the head. Migraine headaches typically last from 4-72 hours. They may occur as often as several times a week to only once a year. People who have migraines are called migraineurs.
Migraine headaches affect about 15% of the population. Three times as many women as men have migraines. Over 80% of migraineurs have family members who have migraines. The following types of migraine headache have been identified:
Migraine without aura (common migraine): This type accounts for 80% of migraine headaches. There is no aura before a common migraine.
Migraine with aura (classic migraine): This type is usually preceded by an aura and is usually much worse than a common migraine. Most often, an aura is a visual disturbance (outlines of lights or jagged light images).
Status migrainosus: This is the term used to describe a long-lasting migraine that does not go away by itself.
What causes migraine headaches?
No one fully understands the exact cause(s) of migraine headaches. Many experts think that a migraine begins with abnormal brainstem (a part of the brain) activity that leads to
spasm (rapid
contraction) of blood vessels in the
cerebrum (main part of the brain) and
dura (the covering of the brain). The first wave of spasm decreases blood supply, which causes the aura that some people experience. After the first spasm, the same arteries become abnormally relaxed, which increases blood flow and gives rise to migraine headache
pain.
Certain chemicals normally found in the brain (namely,
dopamine and
serotonin) may be involved in causing migraines. These chemicals are called neurotransmitters because they transmit signals within the brain. Neurotransmitters can cause blood vessels to act in unusual ways if they are present in abnormal amounts or if the blood vessels are particularly sensitive to them.
Various triggers are thought to bring about migraine in people who have a natural tendency for having migraine headaches. Different people may have different triggers.
- Certain foods, especially chocolate, cheese, nuts, alcohol, and monosodium glutamate (MSG) can trigger migraines. (MSG is a food enhancer used in many foods, including Chinese food.)
- Missing a meal may bring on a headache.
- Stress and tension are also risk factors. People often have migraines during times of increased emotional or physical stress.
- Birth control pills are a common trigger. Women may have migraines at the end of the pill cycle as the estrogen component of the pill is stopped. This is called an estrogen-withdrawal headache.
How are migraine headaches treated?
Self-care at home
Most migraineurs can deal with mild-to-moderate migraine attacks at home. The following measures may help relieve migraine headache pain:
- Using a cold compress to the area of pain
- Resting with pillows comfortably supporting the head or neck
- Resting in a dark, quiet place
- Avoiding odors
- Withdrawing from stressful surroundings
- Sleeping
- Drinking a moderate amount of caffeine
- Taking certain over-the-counter headache remedies: Note that none of the following (with the exception of acetaminophen, aspirin, and caffeine combinations) has been clearly shown to relieve migraine headache pain.

SONG OF THE DAY:
And now, let's put on your dancing shoes and bust your groovy moves with this song of the day.
TITLE: CLOSER
ARTIST: NE-YO
[Verse 1]
Turn the lights off in this place
And she shines just like a star
And I swear I know her face
I just don't know who you are
Turn the music up in here
I still hear her loud and clear
Like she's right there in my ear
Telling me that she wants to own me
To control me
Come closer [x3]
[Chorus]
And I just can't pull my self away
Under her spell I can't break
I just can't stop [x4]
And i just can't bring myself away
But I don't want to escape
I just can't stop [x4]
[Verse 2]
I can feel her on my skin
I can taste her on my tongue
She's the sweetest taste of sin
The more I get the more I want
She wants to own me
Come closer
She says come closer
[Chorus]
Come Closer [x7]
I just can't stop no [x4]
[Chorus]
And I just can't pull myself away
Under her spell I can't break
I just can't stop [x5]
