Traetment of Migrain
In all cases, rest quietly in the dark, away from any aggressive sound and light can not worsen the crisis. Some gestures, vary from one individual to another, have a significant efficiency: hot or cold shower, bath, relaxation techniques, application of cold bag on his head. In some cases, the patient put on oxygen (between 2 and 6 liters minutes) can see her pain diminished considerably. To be effective, treatment should be taken as soon as possible and at best as the precursors of migraine attack, but after the end of the possible will triptans. Indeed, the aura corresponds to a phase of Vasoconstriction prior to a vasodilation headache. Therefore, absorption too early triptan vasoconstrictors may cause symptoms of ergotism. Initially, the proposed drugs are paracetamol, anti-inflammatory drugs, aspirin, which can be associated Metoclopramide (antiemetic neuroleptic), which improves digestion and absorption can alleviate the nausea.
Analgesics should be taken in case of crisis and not daily, or risk a chronic daily headache (QCC, or headache with drug abuse with addiction to painkillers).
In case of failure of these molecules, derived from ergot or triptans may be introduced: they are specific agonists of serotonin receptors vessel extra-and intra-cranial. Their efficiency is very good, the price of side effects and cons, indications that must be weighed against their therapeutic effect. In case of ultimate need, morphine remains a means of last resort.
Migraine is a Hereditary Disease,
starting before 40 years from multiple genes and subject to many environmental factors involved in triggering the crisis.
- Menstrual cycle: before the onset of menses, there is a drop in estrogen levels that commonly leads to a migraine headache (menstrual migraine).
- Individual factors: worries, frustrations, overwork resulting stress can cause a crisis, hard physical or intellectual. Weather: wind, cold or sudden temperature change. Strong odors of certain plants or perfumes.
- Dietary factors: food allergies (eggs, chocolate, strawberries, seafood, alcohol, ice, deli ), rich food, a mixture of alcohol, long-term fasting.
- Disruption of circadian rhythm (excess or lack of sleep, staggered hours
The Aura Migraine
Migraine headaches can sometimes, in some patients, accompanied by sensory phenomena grouped under the name “aura.” This is known as migraines with (approximately 20% of cases). These auras preceding the crisis and usually last less than an hour. Migraine pain follows him, sometimes after a delay of several minutes.
Auras are the most common auras eye: the visual field is filled with phenomena such scintillating points (Phosphenes), flies seem to cross the visual field (Floater) or broken lines of light, can form complex compositions. The visual aura may also include a lateral homonymous hemianopsia (loss of even half of the visual field of each eye), transient monocular blindness, etc.. Sensory auras may manifest as impaired sensitivity to types of paresthesias (tingling, itching) of a hemisomes topography often cheiro-oral (mouth and hand). Other auras are rare, and may pose diagnostic problems: transitory hemiplegia, diplopia with oculomotor palsy, psychic disturbances, auditory hallucinations, speech disorders. In all cases, the signs must decline rapidly and without sequelae. Neurological examination is always normal in migraine (outside of rare complications, see below). In some cases, the aura is not followed by headache.
Migraine Attacks
The frequency of migraine attacks varies greatly from one individual to another. Some people have a few per year, while others have 3 or 4 times per month. In some cases, seizures may occur several times a week, but rarely a day.
The first seizures appear during childhood or young adulthood. Beyond age 40, headaches are more rare and often disappear after 50 years.
Mechanisms of migraine
It is unclear why some people have headaches, tension headaches or migraines, and others have simply never, even if they are exposed to the same triggers.
Years 1960 to 1990, it was believed that migraines were caused mainly by vascular changes, a tightening of blood vessels surrounding the brain, followed by swelling. However, research carried out subsequently showed that the origin of migraine is much more complex. Indeed, a whole cascade of reactions in the nervous system that cause this intense headache. These chain reactions have effects not only on blood vessels, but also on inflammation, neurotransmitters and other elements.
Without a thorough understanding of the mechanisms of migraine, we know still better and better triggers (see Risk Factors) and ways to combat it.
