Symptoms and risk factors Stroke in the elderly

Stroke is a severe neurological disorder that is most common in the elderly and is the third leading cause of death after heart disease and cancer. According to the World Health Organization, there are approximately 15 million people with stroke worldwide each year. On average, every 6 seconds, at least one person dies from a stroke. In 2021, the number of cases of the disease is expected to double.

If an abnormality is found, the face is numb, the mouth is crooked, the speech is blurred, one of the limbs is weak. Difficulty moving It can be a dangerous sign of stroke. Should see a doctor as soon as possible.

Stroke is divided into 2 groups.

  1. Ischemic stroke or thrombosis.
    It can be found in up to 80% of stroke. It is caused by blood clots that have formed from other areas of the body. Flowed by the bloodstream until it clogged the blood vessels of the brain or maybe a blood clot forms in the blood vessels of the brain. and has enlarged and enlarged and clogged the blood vessels of the brain.
    The cause of the narrowing of the blood vessels of the brain is due to the accumulation of fat in the arteries, narrowing the blood vessels, flexibility and the ability to transport blood is reduced.
  2. Cerebrovascular rupture.
    It can be found in 20% of stroke. Caused by fragile blood vessels in combination with high blood pressure. Causing the area to aneurysm and rupture or it may be caused by the blood vessels that lose their flexibility from the accumulation of fat in the blood vessels. This causing the blood vessels to rupture easily, As a result, the amount of blood to supply the brain is reduced sharply, and when the blood vessels are broken It may cause bleeding in the brain, resulting in the rapid death of the patient.

The warning symptoms that are dangerous signs of stroke include blurred or invisible one eye. Blurred or darkened vision, trouble speaking or speaking, weak limbs or face, numbness, or suddenly unable to move. Dazed, dizziness, or loss of balance. A sudden severe headache that was never before, If these symptoms occur, seek immediate medical attention, or if symptoms improve, they should see a doctor immediately.

Stroke disease is a condition in which the brain is the ischemic blood supply. Causing the brain to suddenly stop working From lack of food and blood supply to the brain resulting in brain cell death in the end divided into 3 types:

  • Lack of blood to the brain, Maybe caused by the narrowing or blocking of blood vessels or caused by blood clots to clog the brain.
  • Bleeding in the brain, Which is at risk of high blood pressure with an aneurysm in the brain, Finally ruptured the blood vessels in the brain.
  • Cerebral ischemia in case of transient ischemia, Maybe caused by blood clots to clog, causing the brain to temporarily stop working. The blood clot may then spill out. Causing the brain to return to normal function. In this case, the brain cells will not die. Does not cause paralysis.

Most cerebrovascular diseases are caused by the degeneration of blood vessels. It is more common in older people 65 years and older and is about 1% more common in males than females. However, this disease also has other factors that cause besides the degeneration of blood vessels and can happen at any age. Such factors include accidents. It may cause a rupture of blood vessels or cause blood clots and some may be caused by genetics.

In summary, factors of cerebrovascular disease were:

  • Increased age
  • High blood pressure
  • Diabetes
  • High blood cholesterol
  • Excessive use of certain hormones
  • Smoking
  • Diet

As for dementia, there is a disability at work. To make something go wrong, such as a decrease in memory, ability to think, use of language Arrangement of speech The grading of the direction is lost.
Some people may have mood and personality changes. Sometimes it may not be caused by Alzheimer’s. But maybe caused by the cerebrovascular.

The people at risk for dementia caused by ischemic stroke include people with certain types of heart disease, such as people with arrhythmia. Causing blood clots in the heart to clog blood vessels of the brain can cause dementia, Including diabetes, high blood pressure can be a factor that can lead to a stroke.

Among people with underlying diseases such as diabetes, pressure, fat clogging, this group is at risk. Because blood vessels deteriorate more easily than common people. Usually, blood vessels can contract and expand. But in people with such diseases if they are not well controlled. Will make the blood vessels that have the ability to shrink and expand Causes stiff stenosis and can cause dementia. And although most of the disease occurs in the elderly. But in younger people, it can get this disease. This may be due to diet and other behaviors. For example, people who smoke are also at risk.

The way to take care of patients with this disease is prevention. If you know what risk factors are, they must reduce them. By controlling behaviors that can cause risks, such as eating less sweet, reduced salty foods, reducing it, exercising, and getting enough rest. If you smoke, quit smoking. Or if obese, then lose weight. In addition, if the patient starts to feel abnormal, take them to see a doctor save from the beginning and prevent severe symptoms. However, family members are very important. Is to understand the patient, Because most of these patients easily lose confidence. So encouragement is so important.

Risk Factors for Stroke

  1. Gender, It has been found that males are at greater risk of stroke than females.
  2. Hyperlipidemia, It is a condition in which fat is deposited on the walls of blood vessels Make the blood flow to various parts of the body.
  3. Smoking, Cigarettes contain nicotine and carbon. The amount of oxygen that the body receives is reduced and is also the one that destroys the walls of blood vessels resulting in the arteries to harden.
  4. Conditions of coagulation of the blood faster than normal will result in the coagulation of blood and blood clots more easily than normal people.
  5. Age, when you get older, Blood vessels also deteriorate with age. The inner skin of blood vessels is thicker and harder. Because there are limestone and fat deposits narrowing of the channels through which blood flows.
  6. Heart disease, such as valve leaky heart disease Heart arrhythmia. All of these diseases are the cause of blood clots and if a blood clot is clogged in the cerebral artery, it can lead to ischemia in the brain.
  7. Hypertension This is the most important risk factor for developing a stroke. People with high blood pressure are several times more likely to have a stroke than normal people.
  8. Diabetes causes the hardening of blood vessels throughout the body and if a hardened blood vessel occurs in the brain, it is 2 to 3 times more likely to have a stroke than normal people.

If there are risk factors, treatment, and see a doctor regularly. Never stop taking the drug by yourself. In which people who had previously had a stroke are more likely to recurrently than normal people.
