Recently, there has been a lot of talk about whether the wet freeze in Hong Kong is "the first in the world". However, whether it is a "wet freeze" or a "dry freeze", everyone should pay attention to keeping warm, and also pay more attention to the health of the elderly, because the large temperature difference between day and night can easily stimulate vasoconstriction, causing vasoconstriction. Blood pressure soars, which can lead to stroke and cardiovascular disease (such as coronary heart disease). Furthermore, the onset of disease often occurs suddenly and may not have obvious signs, so risk management should be done as early as possible.<\/p>\n\n\n\n\n\n\n\n

The incidence of stroke is mostly related to the "three highs"<\/h2>\n\n\n\n

In fact, in addition to the elderly, people with the "three highs" (that is, people suffering from hyperlipidemia, high blood pressure, and high blood sugar) should also be more careful. Because fat accumulates in blood vessels over time, it can easily cause blood vessels to narrow or even block, increasing the risk of disease. In particular, the damage caused to the body by stroke cannot be underestimated, so it is also known as one of the "deadly killers" in Hong Kong. According to the Hospital Authority, an average of more than 3,000 people die from stroke every year, and more than 12,000 cases are hospitalized due to acute stroke. Stroke is a cerebrovascular disease. When a blood vessel in the brain is blocked or bursts, brain cells and tissues will be deprived of oxygen and then damaged, affecting the body functions responsible for that part of the brain cells. Patients are usually mature people over 50 years old, but in recent years it has become younger, and people in their 30s and 40s should also be concerned.<\/p>\n\n\n\n

The warning sign of "mini-stroke"<\/h2>\n\n\n\n

To put it simply, strokes are mainly divided into two categories: "ischemic" and "hemorrhagic". About 80% of the cases are ischemic strokes, commonly known as "blood vessels", which are mainly caused by atherosclerosis and narrowing of blood vessels. Or caused by blood clots caused by irregular heartbeats. The remaining cases were hemorrhagic strokes, commonly known as "burst blood vessels", mostly caused by high blood pressure, and may also be related to cerebral hemangiomas or other congenital vascular lesions.<\/p>\n\n\n\n

Some patients have experienced "mini-strokes", which are medically called "Transient Ischaemic Strokes". The pathology is similar to ischemic strokes, except that the blood supply is temporarily blocked, and the neurological dysfunction caused by it will resolve on its own. Recovery, brain cells will not be necrotic. However, patients who have experienced a minor stroke have a significantly increased risk of future stroke, which can be said to be a precursor to a stroke.<\/p>\n\n\n\n

The sequelae of stroke are widely implicated<\/h2>\n\n\n\n

Because stroke causes a large number of brain cells to die due to sudden lack of oxygen, the brain nervous system is damaged, which affects cognitive ability, muscle coordination, activities, swallowing and other functions, and then causes various complications, including pressure ulcers, pneumonia, brain damage, etc. Epileptic seizures, muscle spasms, venous thrombosis in the lower limbs, etc. can cause severe disability or even death.<\/p>\n\n\n\n

Seize the golden time for stroke treatment with the "FAST" mantra<\/h2>\n\n\n\n

Strokes are often unpreventable and occur suddenly. When suspected, patients or their relatives and friends can use the "FAST" formula to make initial identification (this formula is similar to the widely publicized "Talk, Laugh, and Fight"), seize the golden three hours of treatment and seek medical attention as soon as possible to reduce complications. Chances of symptoms occurring:<\/p>\n\n\n\n

F (Face Drooping): The face or corners of the mouth are skewed and asymmetrical;
A (Arm Weakness): Unilateral weakness of arms and legs;
S (Speech Difficulty): Slurred speech or inability to speak;
T (Time to Call): Determine the time of onset and seek help as soon as possible.<\/p>\n\n\n\n

Diagnostic Stroke Test<\/h2>\n\n\n\n

To diagnose stroke, the doctor will first assess the patient's clinical symptoms and risk factors, and then arrange a blood test to understand the patient's blood sugar, blood lipid levels, and coagulation ability, etc., and arrange for a more accurate diagnosis according to the needs of the patient's condition: for example, electrocardiogram display Heartbeat regularity; angiography, including brain computer scan or magnetic resonance, can help identify the type of stroke and affected areas; transcranial\/cervical ultrasound can help understand the circulation of blood vessels in the brain and neck.<\/p>\n\n\n\n

Drugs and stroke rehabilitation are a two-pronged approach<\/h2>\n\n\n\n

Patients with acute stroke generally need to stay in hospital for treatment to stabilize their condition. Depending on the type and extent of the stroke, they may undergo drug treatment or surgery to remove blood clots, hematomas in hemorrhagic strokes, and cerebral hemangioma, etc. Afterwards, the patient may need to receive relevant rehabilitation treatments, including physical therapy, occupational therapy, speech therapy, etc., to help restore body functions and get back on track as much as possible.<\/p>\n\n\n\n

Prevention is better than cure<\/h2>\n\n\n\n

The sequelae of stroke have a profound impact on the daily lives of patients and caregivers. This shows how important it is to prevent stroke. First, establish good habits, including:<\/p>\n\n\n\n
