Migraine Symptoms and Causes |Foods that cause migraine

As a rule, migraine headache mean.But in reality, the disease may take different forms and one of them is a headache.

Symptoms of migraine

What are the symptoms of migraine are there?

main symptoms of migraine include nausea, vomiting and sensory disturbances of vision, hearing and smell.They usually precede the appearance of pain in the head and abdomen.

migraine also may be manifested in the form of the following symptoms:

  • headache (unilateral or generalized);
  • nausea or vomiting;
  • violation of perception;
  • asthmatic aura (mental confusion or dizziness);
  • sensitivity to light or scotoma (blind spot and flashes of light in the eyes);
  • olfactory hallucinations;
  • auditory hallucinations;
  • and other tactile hallucinations;
  • paralysis (always one-sided);
  • speech deterioration (indistinct pronunciation or aphasia).

Perfect description migraine symptoms gave D. Dalessio in his classic textbook on this disease.

What are the symptoms of migraine manifested?

Migraine manifests itself by periodic

headaches, usually one-sided at the beginning of the attack, and then covering the entire head.Getting accompanied by irritability, nausea, sometimes photophobia (photophobia), vomiting, constipation or diarrhea.Often the attacks are accompanied by distorted visual images, flashes of light in the eyes, loss of the right or the left half of the visual field, unilateral sensations in the body or limbs, speech impairments.

Usually the pain covers the parietal, occipital and temporal part of the head, but can spread to the face, and even on the neck.A migraine attack may be accompanied by bloating, blue and numbness of the limbs, vertigo, tremor, pallor of the skin, dry mouth, sweating, chills.

Some people say they feel great the day before the attack, though it has become noticeable change in the condition of the blood vessels.Sometimes there is irritation of the nasal passages, as evidenced by the strong reddening of the nose.

symptoms This list is not exhaustive.If you have a migraine, I take the liberty to assume that you put the diagnosis of an experienced specialist.Headaches are not always associated only with a migraine.Similarly, in addition to migraine headaches may have other symptoms.For example, frequent bouts of nausea and intestinal colic (abdominal migraine).

Causes of migraine Migraine

- a hereditary disease: if one of the parents or close relatives suffering from any form of migraine, you can safely assume that your symptoms also indicate the presence of the disease.

What causes migraine?

In his book Migraine (Migraine) Rodolfo Lowe argues:

  • 30% of all migraine disease occurs before the age of 10 years;
  • 56% people suffering from migraine, her first episode took place before the age of 16 years;
  • 90% of the first migraine attacks occur in people under the age of 40 years.

book Dr. Lowe is mainly devoted to the role of migraine plays low blood sugar.It is well known that hypoglycemia contributes to migraine and headaches, as well as the development of hyperventilation.

causes of migraine

true cause of migraine is unknown, but evidence suggests that it is vascular disease.That is, the development of migraine is associated with disruption of the arterial blood vessels of the brain or abdomen.At the beginning of the attack is their restriction, and then the extension.It is also known that in this process participates depression associated with serotonin.

As a vasoconstrictor in the most painful phase of a migraine attack is usually used the drug on the basis of ergot (ergotamine), which has a marked tonic effect on the peripheral and cerebral vessels, or other drugs, such as Imigran, neutralizing the action of serotonin.Serotonin released

platelets (platelets) in the event that there is a need in their concentration (aggregation) in a particular place in response to damage to the vessel wall.This usually occurs as a response to their damage by free radicals of oxygen.As a result, a certain amount of released platelet aggregation factor.

anoxia means no tissue oxygen necessary for life.Hypoxia means its presence, but in insufficient quantities.When death occurs very anoxia speed during hypoxia, depending on the degree of oxygen starvation, it is a series of changes in metabolism.All this harms the body.

Oxygen starvation migraine

Many scientists withdrawn oxygen starvation during a migraine a special role.The author of one article suggested that each migraine attack is preceded by a short episode of brain hypoxia.

But these conclusions are also consistent with rarely discussed, but truly an established fact that the electroencephalogram (EEG) in migraine, similar to the EEG in all forms of epilepsy, is also directly indicate the presence of hypoxia.In this case, EEG theta waves dominated with a frequency of 4-7 cycles per second.This similarity between patterns of brain electrical activity has led many researchers of the disease, including Wilder Penfield, a Canadian neurologist with an international name, to the conclusion that it was oxygen deprivation (hypoxia) caused by insufficient blood flow to the brain is the cause of the seizures.Renowned Harvard neurologist W. Lennox considered insufficient blood supply to the brain as a result of vasoconstriction caused by hyperventilation when low blood carbon dioxide.In general

electrical brain activity is directly related to the concentration of carbon dioxide in the blood flowing to the brain, since the gas affects the intensity of the cerebral circulation.By reducing the level of carbon dioxide blood flow to the brain is reduced proportionally.In the normal state EGG predominate alpha waves with a frequency of 12 cycles per second, and with a decrease in blood flow rate wave falls to 4-7 cycles per second (theta wave) that corresponds to the state of seizure.

There is no asthmatic, which would not have been hyperventilating and attendant variations in electrical activity of the brain.In those cases where due to a comprehensive program that includes breathing exercises and proper diet, frequency and intensity of migraine attacks decreased, electroencephalogram always showed a corresponding increase in the frequency of brain impulses, ie normalization of state demonstrated.

materials research, by a team of scientists in New York, showed that a similar pattern of EEG related to oxygen starvation of the brain was observed in 30-40% of people suffering from migraine.In fact, it is a large percentage of people suffering from migraine and epilepsy among the relatively high frequency of seizures in patients with migraine have put a doctor on the idea of ​​using for the treatment of migraine in children anticonvulsants.

Amines are protein building blocks of the body.They are produced by himself or come from outside with food.Those bodies can not develop on their own, called essential amines.

vasopressor (vasoconstrictor) amines act as a factor that increases blood pressure.Vasoactive amines cause vascular spasm - alternately narrowing and widening - as is the case of angina and migraine.Dopamine, tyramine and tryptophan, which are among them, play a key role in the onset of migraine.

What triggers a migraine attack?

These amines are stepping up a significant number of mechanisms.Chief among them - the aggregation of platelets.Tryptophan, building block of serotonin is found in many foods.These include milk, meat, turkey, avocado.It is known that the sedative effect of tryptophan.That is why, perhaps you so sleepy after a heavy dinner with roast turkey on Thanksgiving Day.Tryptophan can also trigger a migraine attack.

Release of serotonin in the blood accompanied by the release of histamine.We already know that the histamine - a substance that narrows blood vessels.In the context of vascular constriction platelet accumulation and blood flow slows down.This alone can lead to oxygen deficiency.

tyramine and a high level of relevant hormones may accelerate the emission of blood platelet aggregation factor.That is why the anti-migraine doctor may prescribe beta-blockers, which neutralize the action of hormones.

Increased secretion in the body of these amines, and platelet aggregation factor can occur for many reasons.You find yourself in a stressful situation, and there is an emission of hormones that activate the body's proper response.You load in the circulatory system nutrients, containing tryptophan or tyramine and buoyed platelets.

products that cause migraine

addition to foods high in tyramine (including bananas, prunes, avocados and eggplants), there are other products, such as milk and meat of turkey, with a high content of other amine - tryptophan.Tryptophan is a building block for one of the most important neurotransmitters in the body - serotonin, which has a significant impact not only on a person's mood, but also on the occurrence of chronic pain.

tyramine and tryptophan are associated with the occurrence of migraines, seizures of various etiologies and other neurological manifestations of allergic reactions.These reactions were fully documented, although scientific medical studies of this aspect of clinical practice limited to the study of the role of food allergy in the syndrome of hyperactivity in children.Today it is called attention deficit hyperactivity disorder (ADHD).

Are there foods that cause migraines?

question due to the occurrence of food allergies migraine is reflected in numerous publications.One of the highlights can be found in the Lancet.It carefully analyzed foods high in tyramine, contribute to the occurrence of migraine.

Here is the complete list of these products:

  • milk, cream, yogurt;
  • wheat;
  • chocolate;
  • mature and processed cheese;
  • corn;
  • alcohol (wine, beer, etc...);
  • red meat (beef, etc...), Pork (and out of the products);
  • foods containing monosodium glutamate;
  • licorice;
  • eggs;
  • broths, bouillon cubes, soy sauce;
  • nuts (especially peanuts and peanut butter);
  • dried or pickled herring;
  • seafood, shellfish;
  • citrus fruits (oranges, grapefruit);
  • drink cola;
  • bananas;
  • tomatoes, cabbage, spinach, avocado;
  • canned soups;
  • chicken and beef liver;
  • Products, Processed and smoked meats;
  • plums, prunes, dried figs;
  • raisins;
  • broad beans, lima beans;
  • coffee, tea, cocoa.

All this is well known sources of allergic reactions, although you may suffer an increased sensitivity to other products.The review of recent research on the topic of food allergies and migraines author of the article published in the New York Times, cites data that 75% of patients suffering from migraines, are allergic to the five types of products and more ... and some even twentyand more.

diet Benefits and harms of high-calorie food

If you are a parent, you are probably aware of the role played in the occurrence of migraine-calorie food, which has low nutritional value, and stimulants such as caffeine, preservatives, dyes and various foodadditives.Pay attention to the article by Dr. J. Egger, published in the Journal of Pediatrics, entitled Treatment of children with epilepsy and migraine, using oligoantigennoy diet (oligoantigennaya diet means a diet with a low content of antigens - substances for which your immune system responds antibody production)..Here are the most frequently mentioned in this context products:

  • cow's milk;
  • cheese;
  • pork;
  • chocolate;
  • citrus;
  • wheat;
  • corn;
  • grapes;
  • nutritional supplements;
  • tea;
  • eggs;
  • beef;
  • tomatoes;
  • cane sugar.

Effect of salicylic acid on migraine

Some foods, such as grapes and whole grains contain relatively large amounts of salicylates (salicylic acid salts or esters), substances such as those that are part of the aspirin.These products are able to intervene in the natural secretion of some protective substances called prostaglandins.Most medical scientists have no idea about the content of salicylates in food.Here's an example.The authors of the article published in the Journal of the American College of Cardiology, said the ability of flavonoids contained in grape juice, reduce blood platelet concentration is much more effective aspirin.So, the authors do not even suspect that the vines, and consequently the grape juice as compared to other foods contain more natural salicylates.

How to avoid the syndrome of hyperactivity?

natural salicylates are involved in causing hyperactivity disorder.This was proven by Dr. B. Feingold in the article, which was published impressive results exclude salicylates from the diet of children with the disease.He recommends the abolition of artificial colors and flavors, from the soft drink manufacturing industry, sweets, cakes, puddings, ice cream, breakfast cereals, margarine, processed cheese, and the majority of products such as:

  • grapes;
  • raisins;
  • cucumbers;
  • cherries;
  • apples;
  • apricots;
  • oranges;
  • nectarines;
  • peaches;
  • plum;
  • prunes;
  • tomatoes;
  • strawberries;
  • raspberries;
  • mint.

Dr. Feingold also advised to refrain from taking drugs containing aspirin in its composition.

How to get rid of a migraine?

1.

Be wary of products with a high content of tyramine, tyrosine and tryptophan.And remember that the first effective treatment for disorders associated with the occurrence of migraine attacks, was a nutritional method - ketogenic diet (ketones are the products of fat digestion).

2.

Try to avoid eating sugar, red meat (lamb, beef), wine, bread, milk, corn, licorice, spinach, sodium glutamate and fried dishes.You should also reduce the intake of salt.

3.

Watch out for hand temperature.This is an excellent indicator of the beginning of the attack.

If you can eliminate from your diet foods high in tyramine, not while reducing its energy value, you will soon notice that the temperature of the hands significantly increased.At the same time you will begin to observe reduction in the frequency and duration of attacks.

4.

When perform breathing exercises will have a habit, you will notice a further increase in the average temperature of the hands, reducing the frequency and duration of attacks.

If done correctly, diaphragmatic breathing you will begin to observe a sharp increase in the temperature of the hands - is due to a change in breathing mode!
