Migraine

Migraine is headache pain which recurring idiopatik, usually the one side (unilateral), and beat the headaches. Actually Migraine is not headache because headache can be the one symptom of a migraine attack, but it's just that- one of the possible symptoms, and some Migraineurs (people with migraine disease) have migraine attacks without a headache, these ara called acephalgic or silent Migraines. Migraine is caused by the occurrence of a combination of blood vessel dilation and releasing a substance's chemical fiber - nerve fibers that wrap the blood vessel. The attack onset usually 4-72 hours. During migraine attacks, temporal arterial (arterial that runs around the temple) will be broad. This widening temporal arteri will cause streching in nerve fibers around the arterial thus stimulate nerve fibers release this chemical substance. This substance will cause inflammation, pain and the extraordinary. Migraine can occur in children with the location of pain more often bifrontal

Migraine attacks generally will activate sympathetic nerve. The sympathetic nerve is part of the human nervous system which responsible for controlling the body's response to stress and pain. Increased activity in the intestinal sympathetic nerve causes nausea, vomiting and diarrhea. Increased sympathetic nerve activity will also causes increased sensitivity to light and sound, so migraine patient get photophobia and phonophobia.

Phase of Migraine!!!!!!
In general, there are 4 phases of symptoms, although not all people with migraine experience four phases of this. The four phases are prodromal phase, aura, seizures, and postdromal.

1. Prodromal phase
This phase consists of a collection of vague symptoms not clearly, that may precede migraine attacks. This phase can last for several hours, even 1-2 days before the attack. Symptoms include:
a. Psychological: depression, hiperactivity, euforia (rapture excessive), communicative (talkativeness), sensitive / iritable, anxiety, sleepy or lazy.
b. Neurologis: sensitive to light and / or sound (photophobia & phonophobia), difficulty concentrating, excessive vapor, sensitive to the smell (hiperosmia)
c. General: stiff neck, nausea, diarrhea or constipation, crave or increased appetite, cold, thirsty, felt slow, often dispose of urine.

2. Aura
Generally perceived aura symptoms precede the attack of migraine. Visually, aura is expressed in the form of positive or negative. Migraine sufferer can experience both at the same type of aura.
Aura looks like a positive light sparkler, as a form of cover around the edge pengelihatan field. This phenomenon is also known as a scintillating scotoma (scotoma = defect field perspective). Scotoma can eventually expand and cover the entire field perspective. Aura can also positively shaped like lines zig-zag, or the stars.
Aura negative hole looks like dark or black spots that cover the field of vision. Also shaped like a tunnel vision, where the field perspective into both sides of the dark or closed, so that the field perspective is focused only on the middle.
Some Neurologic symptoms can appear simultaneously with the occurrence of aura. The generally Symptoms are: talk interference; pins; sense of Baal; feeling weak at the bottom of the arm and leg; vision perception disturbances such as distortion of space and confusion.

3. The attack phase
Without treatment, migraine attack usually lasts between 4-72 hours. Migraine with aura are called classic migraine. While migraine without aura is a common migraine (Common Migraine). Symptoms commonly include:
a. Head aches that one side feels like a pulse-beat . Pain can sometimes spread to the whole head
b. Head aches weight gain when conducting activities
c. Nausea, sometimes accompanied by vomiting
d. Symptoms vision interference can occur
e. parestesy
f. Very sensitive to light and sound (photophobia and phonophobia)
g. Generally look pale face, cold body and
h. There are at least 1 aura symptoms (in the classical migraine), which developed gradually over more than 4 minutes. Head aches can occur before symptoms of aura or at the same time.

4. Phase Postdromal
After a migraine attack, usually occurs prodromal period, where patients can feel tired (exhausted) and feeling like mist.



There are types of Migraine
1. Classical Migraine (Migrain with Aura/MWA)
2. Varian Migraine
3. General Migraine (Migrain without Aura/MWOA)
4. Associated and dissociated Migraine
5. Complicated Migraine
6. Status Migrainous
