What Is Migraine?

Headache Health

Migraine usually begins early in the morning or during the day by a pain intense, constrictive, located in one half of the face, to expand further. Typically, it reaches a maximum intensity of four hours and two days if not treated.

Sleep generally improves symptoms, but can be dizzy after waking, inattentive. The frequency of attacks can range from daily attacks and occasional attacks. Migraine attacks may be accompanied by nausea and sometimes vomiting. Signs and symptoms of migraine headache moderate or severe nausea, vomiting, sensitivity to light and noise, fatigue, aura consisting of colored circles or white spots in your vision.

The causes that lead the occurrence of migraine cause of migraine are unknown precisely. The researchers suggest that it is related to an imbalance of the neurotransmitters serotonin and possibly other brain. Serotonin regulates the transmission of pain messages by way of a trigeminal nerve major pathway of pain. Changes in the activity of norepinephrine may be responsible for aura that many present immediately before installing migraine. During migraine attack, reduce brain levels of serotonin.

The researchers believe that this causes the trigeminal nerve to release substances called neuropeptides, which runs to the outer jacket of the brain causing dilation and inflammation of blood vessels. The result will be a headache. Many aspects related to migraine remains unknown, but experts believe that this type of headache begins in the brainstem initially, and then follow irradiation to the trigeminal nerve, which is a major pain pathway in the brain. From here, moves to the blood vessels of the brain at the level of the outer casing. Blood vessels dilate, swell, blocking the sensation of pain.

As the magnesium concentration falls immediately before or during the production of migraine, it is possible that low levels of these mineral substances involved in the proper functioning of neurons to produce malfunctions of the brain nerve cells. Migraines have different clinical forms: migraine with aura and migraine without aura. In the case of migraine with aura, some people get some neurological warnings 5-20 minutes before the attack of migraine. This warning, called aura may consist of brilliant flashes of colored lights, zigzag lines, dark spots that grow progressively and feeling dizzy.

Rarely, these symptoms may persist, perhaps due to a stroke. Migraine without aura start gradually without any warning characteristic symptom. With hours before the migraine can feel a good mood, be full of energy, you feel thirsty, a craving for sweets, irritability or depression. They are often considered premonitory symptoms. Typically, migraine reaches maximum intensity within a few minutes or more.

Less common types of migraine include migraine with aura and paralysis (called familial hemiplegic migraine, migraine this is the paralysis of one half of the body. The patient has at least a close relative with similar attacks); migraine with aura without headache (migraine this is more on older adults); migraine status (this is a headache that lasts more than 72 hours); infarction migraine (migraine in this type of one or more of the symptoms that constitute aura persist for more than 21 days).
