Migraine is a neurological problem that is characterized by chronic headaches, often accompanied by nausea and sensory changes. Most migraine experts believe that many migraine headaches triggered by a number of different events, including environmental food and beverages, are weather and other factors. Research suggests that migraine triggers vary from person to person. In general, migraines are very painful, one-sided and may take 4-72 Clock. Most migraine symptoms are heightened sensitivity to light and sound, nausea and vomiting. More than half of migraine patients, aura-visual perception unusual, aromatic or any other type of sensory experience, which always arise before the headache begins.

After the scientific literature there are four main groups of migraine studies that follow different process for determining the trigger migraines. They are, as already mentioned:

Challenge studies here are migraine patients aware of factors that can act as potential triggers to see if the pain occurs or not suspended. Researchers have found this very experimental approach very strong evidence of the cause-effect relationships between, triggers and headache.

However, some experiments with the challenge of a misguided approach to confirm the results, triggers, most of these studies do not specifically focus on individuals reporting a particular vulnerability to the withdrawal of the investigation.

Therapy studies for this branch of study, which suffer from migraines, are asked to avoid any contact with a certain set of migraine triggers (particularly suspicious food) for a period of time to see if this reduces the rate / frequency of headaches. This step helps in identifying the triggers that, if it does not prevent headaches.

“Treatment trials” are generally considered to be a mixed bag, as some studies positive effect of the control diet, which eliminates a large number of food report, while other studies say there are no advantages. In general, it is difficult to get many people to meet the faithful with food regiments in which many of their favorite foods “off limits”. For this reason, the study treatment approach not given either a general or robust effective therapy research.

asked in the diary studies, patients to receive a record of the headaches and what were the factors they are exposed to a list of presumed to have triggers. Some studies have used statistical analysis to check whether there is a strong cause-effect relationship between exposure and later trigger a headache.

Survey studies in survey studies, the patients asked their views about what they do think and have observed, the cause of headaches.

In 1995, Silberstein and his colleagues, a survey of 500 migraine patients and found the following percentages believe that their headaches were in demand by different types of triggers such as:

Stress

79th 0%

Changes in the weather

44th 0%

Before menstruation

37th 2%

Changes in Light

33rd 8%

Eating certain foods

30th 0%

During menstruation

26th 8%

Fatigue / Insomnia / Other

6th 6%

Other events (combined)

13th 2%

These are some of the methods for identifying the source of a person could be and what causes migraine before it becomes painful. The results of these studies together, make clear that migraine triggers is a reality. Nevertheless, the heterogeneity of the results strongly suggest that different individuals of different migraine triggers. So, patients with migraine headaches can avoid not only to prevent items from lists of common triggers, but they are for more effective prevention, if, as the cause of their headaches to determine in particular.
