◆ Prevention of stroke during the change of seasons
Stroke is a disease in which the blood vessels in the brain rupture, narrow or become blocked, causing ischemia in the ventricles supplied by the blood vessels. When anemia occurs, necrosis occurs due to a lack of oxygen in the brain parenchyma and a lack of nutrients.
Stroke rates tend to increase with the changing seasons. When the weather changes from hot to cold, our body tends to constrict blood vessels. This makes high-risk people more likely to have a stroke.
People at high risk for seasonal stroke are people with high blood pressure, people with vascular disease, vascular strictures, and the elderly with underlying conditions such as diabetes and fat in the blood. These have abnormalities or malformations of the brain blood vessels.
Currently, stroke increases and tends to recur due to the influence of the living environment, inactivity and unhealthy habits such as overeating, which increases the risk of metabolic disorders. Furthermore, the percentage of people with diabetes, hypertension and obesity also increases the risk of stroke.
The symptoms of a stroke are often confused with other conditions. However, signs of loss of balance, abnormal dizziness, instability and impaired coordination of the limbs are signs that can be easily confused with vestibular syndrome and require special attention.
The signs of an unusually intense headache are also signs to watch out for as this condition is common in young people but easily overlooked.
Stroke can occur at any time, even while we sleep. Ischemic stroke is a common type of stroke during sleep because blood pressure tends to be lower and cardiac output is lower than when awake. Hypotension and low cardiac output against the background of stenotic and ruptured coronary arteries can lead to cerebral ischemia and stroke.
About 80% of stroke patients remain conscious and can recognize the signs of stroke, and 20% of patients can lose consciousness and fall into a coma.
Therefore, when it detects the signs of a stroke, it can alert the surrounding environment and limit falling or bumping into nearby objects by lying in a well-ventilated area.
The best way to prevent stroke is to have regular checkups and check risk factors for early treatment.
