Stroke: The Real Danger Behind This Serious Disease 

Tuesday, September 13,2016

A cerebro-vascular accident (CVA) or stroke, is abnormal flow of the blood which affects a region more or less of the brain. It occurs as a result of blocked or damage of the blood vessel and lead to the death of nerve cells that are deprived of oxygen and nutrients essential to their functions. In most people, there is no precursor to an attack. However, several risk factors can be monitored.

Strokes have very different consequences. More than half of people are affected negatively. About 10% individuals is completely cured.

The risk depends on the region of the brain damage and the functions it controls. More oxygen-starved region, the greater the effects are likely to be important. Following a stroke, some people have difficulty speaking or writing and he have a problem in memory. They may also be achieved a more or less substantial paralysis of the body.

Types of stroke

Ischemic stroke

In eight out of ten cases, strokes are ischemic strokes: the interruption of blood flow is due to a clot (coagulated blood) that blocks an artery to the brain.
The main cause is atherosclerosis; it is an accumulation of cholesterol deposits on the artery walls. These deposits progressively harden and form atherosclerotic plaques that narrow the arteries and promotes clot formation. In some cases, a plate fragment can also break off and go obstruct an artery within the brain.
Sometimes, the origin of the stroke is the formation of a blood clot away from the brain, for example in the heart. This clot is then carried by the blood to the brain.

Hemorrhagic strokes

They are less common (20% of cases). Stopping the flow of blood is due to the rupture of an artery of the brain.
The main cause of hemorrhagic stroke is high blood pressure.
Read the article: High Blood Pressure
In some cases, the rupture can occur on a pre-existing condition of the artery aneurysm or arteriovenous malformation.

Cerebral thrombosis

It represents from 40% to 50% of cases. It occurs when a blood clot forms in a cerebral artery, a lipid plaque (atherosclerosis).

medical emergency

When nerve cells are deprived of oxygen, if only for a few minutes, then die; . Also, time between stroke and medical care are very short, the risk of severe sequel is shrinking.

Whatever the damage caused by oxygen deprivation, the brain has some adaptability. Healthy nerve cells sometimes manage to take over the dead cells if they are stimulated by various exercises.

causes

Atherosclerosis, that is to say the formation of lipid plaques on the walls of blood vessels, is one of the major causes of stroke. Hypertension is an important risk factor. Over time, the abnormal pressure exerted by the blood on the wall of blood vessels can cause them to break. The rupture of an artery in the brain can be facilitated by the presence of an aneurysm. The aneurysm is a swelling of a small section of an artery due to weakness of the wall.

It is not always possible to determine the exact cause of stroke. It is important, however, that doctors seek it by performing various tests in order to reduce the risk of recurrence.

What are the symptoms of stroke?

In general, there are no or few signs that herald the onset of a stroke. Symptoms appear suddenly and depend on the area of the brain damage:

– Numbness on one side of the body
– Lyrics confused, difficulty understanding what you are told or inability to speak
– Loss of vision or blurred vision in one eye
– Weakness or inability to move one side of the body
– Tremors, clumsiness or difficulty moving
– Severe headache
– Vomiting, dizziness, difficulty with balance

Risk factors
The factors that you can not act

age

The risk increases with age after age 50 in men and after age 60 in women.

Family history

The risk increases if, in your family:
a close relative (father, mother, brother, sister) presented a cerebrovascular accident (CVA) before age 45;
your father or brother presented cardiovascular disease (myocardial infarction or sudden death) before age 55;
your mother or sister presented cardiovascular disease (myocardial infarction or sudden death) before 65.

Risk factors that you can act

Learn to identify cardiovascular risk factors not to underestimate them.

Diabetes

One speaks of diabetes when blood sugar (blood sugar or glucose) is greater than 1.26 g / l fasting in two steps. If you have poorly controlled diabetes, excess glucose in your blood can damage the walls of your arteries.

High blood pressure

We talk about high blood pressure (hypertension) if:
systolic blood pressure exceeds 140 mmHg or 14 cmHg;
and / or diastolic blood pressure is 90 mmHg or 9 cmHg.
Atrial fibrillation
Atrial fibrillation (atria of the heart beat very fast) is a factor that can be treated.

smoking

Tobacco promotes narrowing of the arteries, blood clots and the development of cardiac rhythm disorders. Smoking increases by 2 the risk of stroke.
Read the article about: Smoking

A high cholesterol

We distinguish the bad cholesterol (LDL) cholesterol levels of good cholesterol (HDL cholesterol). If you eat too much fat, if you suffer from obesity or if you do not practice physical activity, and increases bad cholesterol accumulates on the walls of your arteries as fatty deposits. Over time, these deposits can slow and block the flow of blood is atherosclerosis.

Obesity and overweight

We speak of overweight when the body mass index (BMI) greater than 25 and obese if it is greater than 30.
The presence of abdominal fat is a risk factor. There is talk of abdominal obesity when waist circumference exceeds 88 cm for women and 102 cm for men.

Physical inactivity

That is to say, if you made less than 30 minutes of physical exercise a day.
Read the article about: Walking

The alcohol

Alcohol, whatever its level increases the risk of hemorrhagic stroke. A consumption of more than 30 drinks per month and / or the practice of binge drinking increase the risk of ischemic stroke.

How to prevent The stroke?

– While following his treatment for diabetes, high blood pressure or cholesterol.
– If you are at risk, your doctor may prescribe a daily dose of aspirin to reduce the risk of forming a blood clot.
– Avoid smoking or quit smoking
– Drink alcohol in moderation
– Eat a balanced diet, do physical exercise regularly

Making good food choices: diet affects several stroke risk factors.

Researchers reviewed 375 studies published between 1979 and 2004 to identify the type of power that best helps prevent Stroke. According to their analysis, a low-salt diet (less than 1150 mg per day) and rich in potassium and magnesium lowers blood pressure and, thus, helps to prevent stroke. diet containing vegetables-fruits which they are a source of antioxidant elements gives adequate amounts of potassium. Whole grains, nuts, seeds, legumes and dark green leafy vegetables are good sources of potassium. Studies show that people who eat about 10 servings of fruits and vegetables a day, that emphasize whole grains and eat from January to February servings of fatty fish per week are less likely to suffer a stroke.

In terms of the plans, it was shown that  the Mediterranean diet helps prevent hypertension in an effective way.

Learn to better cope with stress;
Change contraception if necessary. Women over 35 who take a contraceptive pill and are considered at risk (because they smoke or because they have high blood pressure …) should opt for another method, such as a device intra- uterine or pill which contains only progesterone.

Submit to examinations and medical treatment

Consult your doctor at the recommended frequency by it. When a patient is at high risk of having a stroke, the doctor may listen to the stethoscope the sound of his carotid arteries. If he suspects that artery affected by atherosclerosis, it recommends a Doppler ultrasound of the carotid. This exam will determine the degree of narrowing of the artery;

Regularly monitor blood pressure and if you have high blood pressure, treat, even if asymptomatic. This is the most important risk factors to control. Healthy eating (it is important, among others, to avoid very salty food), the practice of physical exercise, moderate alcohol consumption and the fact of quitting are some measures that help reduce the pressure blood. Medications such as diuretics or beta-blockers may be required. View the file Hypertension for more information.

Frequency. Blood pressure should be taken by the doctor at the time of the periodic health examination;
Proceed regularly to a balance of blood lipids. Take steps to correct the anomalies. See our Hypercholesterolemia sheet.
Frequency. In Canada, it recommends routine screening every 5 years for men over 40 and postmenopausal or women over 50 years. People at risk (those with diabetes, hypertension, smoking, abdominal obesity, family history of cardiovascular disease, etc.) should undergo more frequent screening;

Check or regularly your blood sugar in order to prevent diabetes. In addition, although glycemic control if you have diabetes.
Frequency. At the time of the periodic medical examination, if the doctor considers it necessary, it may order a fasting glucose test;
Consult your doctor immediately in case of abnormally fast or irregular heartbeat;
Treat heart disease.
