High incidence of stroke in winter: beware of stroke in the elderly

Winter is the high incidence season of stroke. Because the weather is cold, blood vessels contract, blood pressure will increase, and people's cerebral vascular blockage is easy to bleed. Therefore, cerebral hemorrhage peaks from December to February of the next year. However, while paying attention to the prevention of stroke, many elderly people ignore extracerebral stroke.

High incidence of stroke in December and January

According to statistics, more than 70% of stroke patients in previous years occurred in December and January. Stroke is a general term for cerebrovascular accidents. Due to the acute onset, fierce coming, difficult to predict, high mortality and disability rate, because the disease mostly occurs in the middle-aged and elderly, and more than 80% occurs in winter, medical experts also call it 'the epidemic of the middle-aged and elderly in winter'.

Medical meteorology research shows that the weather turns cold in winter, the temperature, air flow and other meteorological elements change violently, and the cold air continues to invade. After the human body is frozen, it leads to the excitement of sympathetic nerve, the spasmodic contraction of capillaries in the whole body, the increase of peripheral resistance of blood circulation, the increase of blood pressure, and platelets are easy to agglutinate and form thrombosis. In addition, because the physiological function of the middle-aged and elderly decreases, and their adaptability, stress and resistance to changes in the external environment are reduced, it is very easy to have a stroke in winter. " Three high 'middle-aged people are not easy to avoid stroke.

Here are some easily overlooked extracerebral strokes:

1. 'eye stroke'

The disease is frequent in the elderly, especially those with arteriosclerosis, hypertension, diabetes and hyperlipidemia. This kind of stroke is relatively sudden. The main symptom is painless but rapid vision loss. Many patients have the experience that their eyes are good. When they wake up, they find that they can't see anything. When the seasons alternate and the temperature changes greatly, it is often the high incidence season of 'eye stroke', while in the early morning, it is the high incidence period of 'eye stroke'. Therefore, after waking up, if you find that your eyesight decreases sharply, you must see a doctor in time.

2. 'abdominal stroke'

The disease is caused by the rupture of aneurysms of small branches of intra-abdominal arteries or the rupture of weak areas of atherosclerosis. Acute onset, severe abdominal pain, peritoneal irritation, rapid shock, dangerous condition and poor prognosis. The etiology of the disease is not completely clear, which may be related to hypertension, arteriosclerosis, inflammation, bacterial infection, etc. when the elderly with these diseases have severe abdominal pain, they must go to the hospital in time.

3. 'leg stroke'

The disease is called acute embolism of lower extremity artery in medicine. The normal blood circulation of human lower limbs is that the blood is output from the heart and transmitted to both lower limbs through the aorta and iliac arteries on both sides. All the functions of skin, muscle and nerve tissue of both lower limbs depend on the blood supply of arteries. When the arterial blood flow is blocked, the skin, muscle and nerve tissue within its supply will suffer ischemic damage, resulting in a terrible 'leg stroke'. Data show that 80% ~ 90% of patients with lower extremity arterial embolism suffer from heart disease. It can be seen that mural thrombus from the heart is the culprit of 'leg stroke'. Therefore, to prevent 'leg stroke', we must first scientifically treat heart disease.

Experts remind: don't ignore the early signs of stroke attack

The onset of stroke is sudden and difficult to predict, but there will be some early signals before the onset. If we can understand these signals and actively prevent and control them, we will greatly reduce the harm and even prevent the disease. Therefore, once the following signs appear, we should be highly vigilant and send them to the hospital for diagnosis and treatment immediately. Sudden dizziness or aggravation of headache; Blurred vision or blindness; Sudden hardening of the root of the tongue or aphasia; Sudden numbness, fatigue and inconvenient movement of one limb; Mental fatigue, frequent yawning, nausea and vomiting; ' Personality 'mutation, mental decline, lack of normal judgment and understanding; Unexplained drowsiness, etc.
