High blood pressure threatens to stroke and dementia








Because of its effects on the brain arteries
High blood pressure, a disease of the circulatory system. And appear to many diseases of patients in the coronary arteries or cases of heart failure, which leads to the deaths of many of them the result. However, all members of the body depends on blood circulation, and therefore many of them suffering from the effects of high blood pressure, if not addressed. The brain is one of those members exposed to grave danger.

Blood Pressure

* The blood pressure, a vital force to push the blood saturated with oxygen to all parts of the body. The heart is a pump that generates the force, while the channels are the arteries that carry blood and distributed.

Is determined by the highest value of blood pressure how to contract it strongly, the heart chamber Aldhakp Home, which the left ventricle, as determined by diameter arteries and the extent of hardening. However, the heart and arteries are affected part, a large number of genetic factors, hormonal, metabolic (metabolic), neurological, psychological, as well as lifestyle factors, which determine the whole blood pressure. Because these effects are multiple and complex, the amount of blood pressure can be between the value and other than an hour to one hour during the times of the day, in addition to the slow changes that occur during the life of him. And his blood pressure values. Rapid economic systolic blood systolic blood pressure represents the highest value recorded when the heart to pump blood to the arteries. The diastolic blood pressure, diastolic blood pressure, which is the minimum value recorded when the heart relaxes and is fullness of blood in the period between pulses.

And measured values both Bmellimtrut mercury (mm Hg), a value that corresponds to part of a column of mercury in the first pressure measuring devices have been used by more than 100 years.

As is customary, the highest value of the little first, then followed by the minimum value: the systolic pressure of 110 mm Hg and diastolic pressure of 70 mm Hg will write as follows: 110/70 mm Hg.

In adults, the values are Tabieitan less than 120/80. The diagnosed cases of high blood pressure, hypertension when the values are 140/90 or more, while the classified values between 120/80 and 139/89 as of «pre-high blood pressure» prehypertension.

The cases of high blood pressure, many common, and suffered about 74 million Americans - about one out of every three adults, with Nearly 54 million of pre-hypertension. And high blood pressure lead to serious consequences, since it is responsible for the death of one out of every six adults. Because this disease involves the heart and blood vessels, it is classified as a «disease of the heart and blood vessels». But, as long as the arteries are vital to the health of all members of the body, high blood pressure can be considered a disease affecting the various systems are vital for the body, at the helm of high blood pressure in many cases, the effects do not fall within the scope of the heart, but rather would encompass about the eyes, kidneys, and the brain in particular.

* Stroke

* Although the risk of death because of the American individual stroke stroke is reduced by almost 70 per cent of what it was in 1950, stroke remains the third most common cause of death in the United States. And a further stroke about 800 thousand a year, die 45 per cent, while suffering many of the survivors of the difficulties of disability. It is the U.S. economy because of the costs of large amounts of up to 69 billion dollars per year.

* Types of Stroke

* There are two main types of stroke: stroke, ischemia (obstructive or inertial) ischemic stroke, hemorrhagic stroke, and hemorrhagic strokes. And haemorrhagic stroke is less common but the most serious repercussions, it occurs when a blood vessel bursting, which leads to leakage of blood to the brain or the fluid surrounding it.

The stroke, ischemia that occurs in 87 per cent of all incidents of stroke is caused by blockage of an artery equipped with blood, Bouktherp bloody. Can this occurs in one of two ways. In the first method occurs Stroke Named Ktharip Altjlatip or thrombotic stroke, when the blood clot formed inside the artery infected with located within the brain itself. In the second method spoke stroke «stroke of Foreign Affairs» embolic stroke (stroke Ansmamep) are formed clot outside the brain with blood and then move him, to fill the artery properly located. The majority of this second type of blood clots forming in the sediment resulting from the hardening of the arteries, either in the carotid arteries or the aorta or the heart.

There is, for every one of these main types of stroke, types of strokes and light. Although it is possible to monitor large haemorrhagic strokes, the studies that employed the device magnetic resonance imaging also showed that many small blood leaks common. By the same token a lot of people suffer from obstructive types of small strokes. Although these two types of small strokes do not lead to the emergence of symptoms associated with, the series in a row of them may lead to major problems such as memory loss or cognitive impairment.

According to estimates by the American Medical Association, more than 13 million Americans have suffered from one or more strokes «small», which is more common among persons aged 60 years or older, especially those with high blood pressure.

* High risk

* High blood pressure is the main cause of stroke, whether obvious symptoms, or silent. And contribute to both values of systolic blood pressure and diastolic in danger of occurrence, the greater the values of blood pressure readings, the greater the risk. According to a study from Harvard University, the high blood pressure increases the risk of stroke for men increased by 220 per cent, while the study indicates again that every increase of 10 mm Hg in systolic blood pressure increase the risk of stroke, cerebral ischemia by 28 per cent, and the risk of stroke haemorrhagic fever by 38 per cent.

This is bad news. The good news is that the treatment of high blood pressure helps force, to be protected from a stroke. In a rough calculation, the success of human reduce the amount of systolic blood pressure by 10 mm Hg, will reduce the risk of stroke by up to a high 44 per cent.

* Dementia

* High blood pressure affects and in accordance with recent studies on the brain and cognitive abilities in the elderly patients. Although it was easy to deal with cases of mild cognitive impairment, it is difficult to deal with cases of loss of memory or mental deterioration of the trial, the cases in which scientists today call «dementia».

Among the many reasons that lead to neurological dementia, there are two main reasons for the lion's share to it, namely: frequent incidence of heart blockage multi - infarct, or so-called «dementia, or dementia, vascular» vascular dementia, and Alzheimer's disease.

Show cases of dementia, heart blockage repeated, when infected small blood vessels in the brain diseases or become blocked, depriving brain cells of the required nutrition of oxygen and glucose. When large amounts of damaged neurons by this process, it can not be retrieved memory. The Alzheimer's Disease it is different, as shown by injury after an accumulation of large quantities of material «beta - amyloid» beta - amyloid, a sticky protein small overlap with the function of neurons and thus lead to loss of cells, leaving deposits of neurological beyond. In advanced cases of this disease the brain cells become clogged with material from nerve fibers composed of proteins called «Tao» tau. In most cases, part of the brain responsible for memory (the hippocampus hippocampus) affected more than others.

* Blood pressure, impaired memory

* Because high blood pressure, damage the arteries, it is easy to see how the leads are responsible for vascular dementia. In spite of the absence of a clear link between the damage and the incidence of Alzheimer's disease, the research assumes that the damage to blood vessels and inflammation of the tissues faster in incidence of the disease.

Details vary between the study and the other, but the weight of evidence is now supposed that the high blood pressure increases the risk of cognitive impairment and vascular dementia, and even the risk of Alzheimer's disease. Leads both quantitative systolic pressure, and diastolic, to this damage. In general, the higher the amount is higher, the longer he was without treatment, the risk is greater.

And focus the majority of research on older adults. For example, have found a study of 2505 men between the ages of 71 and 93 years if they have the amount of systolic pressure 140 mm Hg or more, cases of dementia appear to have 77 per cent more, compared to the others who have the amount of systolic pressure with less than 120 mm Hg. The study evaluated the blood pressure and function of awareness among people from two categories: between the ages of 18 and 46 years old, and between 47 and 83 years, that the amounts in the Height in systolic blood pressure and diastolic blood pressure in individuals of both categories, related to deterioration in the capacity of perception, with the passage of time .

The doctors were able to alleviate the burden of dementia they will not succeed in reversing the damage, and reverse the disabilities incurred. Therefore, prevention becomes very important.

* Stop treatment of dementia

* Is it possible to treat blood pressure can help ward off dementia or dementia? The answer is yes. European researchers have reported that treatment of high blood pressure in the long term reduces the risk of dementia by 55 per cent. However, a number of American studies present the results of the least optimistic. One stated that the treatment reduces the risk by 38 per cent. As stated again that each year of treatment associated with reduced risk of dementia by 6 per cent, and the back of that, particularly in men who were treated for 12 years or more, it had lower incidence of Alzheimer's disease by 65 per cent, compared to men who were not given. The third study, conducted on men and women to the Americans that the treatment led to reduce the risk of Alzheimer's disease by 36 per cent. The diuretic drugs more useful. The team of researchers from Harvard University and Boston reported that the 6 types of treatments for high blood pressure, improvement in the reality of the process of blood flow to the brain.

* Do not delay treatment

Q: But it's good to treat high blood pressure reduces the risk of dementia. But what is the case for people who suffer from mild memory loss? Is it possible to treat high blood pressure, prevent further damage to them?

Answer: Maybe. The Italians, researchers looked at 80 patients with mild cognitive. During the period of one year and a half of the study, it appeared that the trend towards risk of Alzheimer's College, say 80 per cent among treated compared with other non-therapists. However, the study was a single, small and require additional research.

* Stroke .. Kinds

* Haemorrhagic stroke, hemorrhagic stroke:

- Occurs in 13 per cent of cases of stroke.

- Occur because of the blood vessel burst and leak blood into the tissues.

- More dangerous than the stroke ischemia (obstructive).

* Hemorrhagic stroke in under the membrane in the brain Spider subarachnoid hemorrhage:

- Bleeding around the area between the brain and skull.

- Appear often in the blood or aneurysm, a condition created an area where an expansive and weak in the wall of the artery.

* Within the brain hemorrhagic stroke intracerebral hemorrhage:

- Bleeding from a blood vessel inside the brain. Often occur because of high blood pressure and damage caused by the arteries.

* Stroke, ischemia (obstructive or inertial) ischemic stroke - occurs in 87 per cent of cases of stroke.

- Caused by a blockage in a blood vessel in the brain.

- Die brain tissue when blood flow to it.

* Ansmamep stroke embolic stroke:

- Caused by a blood clot formed in the remote site and then moved to the vessel in the brain bloodless

* Occur in 60 per cent of all cases of stroke among Americans. And 25 per cent of this type of stroke associated with atrial fibrillation (irregular heart rhythm)

* Ktharip stroke thrombotic stroke - caused by a blood clot formed as a result of narrowing of the artery after being infected with hardening of the arteries.

* Control your health .. Monitor and to change your lifestyle

* For the health of your mind and the health of your body, you have to measure the amount of your blood pressure. Always remember that people who have normal blood pressure lived more than five years ago of those who suffer from high blood pressure.

The first step is to know your blood pressure, as no one knows about 20 per cent of the people that they suffer from high blood pressure. The second step to know your goal. If you are in the scope of «pre-high blood pressure», always tried to reduce the pressure to less than 120/80 mm Hg. As with high blood pressure, they should reduce their amounts to less than 140/90 mm Hg. But people with diabetes, kidney disease and coronary artery disease, or peripheral arteries, or carotid arteries, or disease, or blood in the aorta, the goal is to reduce the pressure to less than 130/80 mm Hg.

The third step is a change in lifestyle, including:

* Diet: reduce the amount of sodium intake to less than 2300 mg. The amount of the new is 1500 mg for people with high blood pressure of healthy adults in midlife. As well as reduce the vegetable fats and processed foods, and eating large amounts of fruits and vegetables, whole grains, fish and dairy products demilitarized or low-fat. And reduces the good food of the systolic blood pressure between 10 and 22 mm Hg.

* Sports

* Weight Control

* Use non-drug anti-inflammatory Alstreodip wisely, since drugs such as «Ibuprofen» «Naproxen» and others, can raise blood pressure, especially for the elderly.

* Stay away from the tension.

* Finally, take the drugs prescribed to you.
