Because it is easy to sweat in summer, resulting in excessive water loss, making blood sticky and blocking blood vessels, and the temperature difference between indoor and outdoor caused by air conditioning is also easy to cause blood vessel contraction, so the probability of stroke is not lower than that in winter; Many people often feel dizzy after sweating. In fact, it is very likely that the blood is too thick, and even they have symptoms of "small stroke".
Although a minor stroke is only a temporary cerebral ischemia, even if symptoms appear, it will be all right as long as you rest for 5 minutes, and it is easy to be considered as "too tired" or "too busy" to pay attention, but in fact, the probability of another stroke after a minor stroke is particularly high. According to your own "stroke risk assessment form", you can avoid a major stroke, but you can't know the warning immediately.
Stroke Risk Assessment Table: Ischemic stroke is the main stroke in ABCD2, accounting for about 70-80%, that is, ischemia caused by blood vessels blocking the passage of blood in the brain, while mild stroke in general cognition is "temporary ischemia", accounting for 30% of ischemic stroke, with symptoms lasting only about 5-20 minutes, and discomfort can be recovered within 24 hours, so it should not be too harmful to the brain.
However, the brain is a very fragile organ, and temporary ischemia may lead to the death of some brain cells. Moreover, when symptoms appear, it is impossible to confirm the ischemic brain area and judge whether blood vessels or capillaries are damaged. Even if it is temporary, it can't be considered as a "small" thing.
One-sided, a small number of hands and feet on both sides, or sudden numbness and weakness in the face, can not affect the facial muscles when smiling, leading to confusion when speaking askew, and suddenly feeling confused and unable to understand what others are saying. When walking, driving or cycling is good, I suddenly feel dizzy and have a headache, but when turning or reversing, I don't know why my personality suddenly becomes irritable and my memory drops. Although mild stroke is different from the "hemorrhagic stroke" that most people are afraid of, it will not faint and die on the spot, but it is the most common and easily overlooked stroke, and its incidence rate is five times that of other strokes, and its symptoms are mild. However, compared with other strokes that affect the function of hands and feet, it is more likely to unconsciously affect cognitive function and lead to the above vascular dementia.
Moreover, it can lead to a slight stroke. In fact, there are already risk factors for stroke, such as obesity, three highs, smoking and drinking, cardiovascular disease and so on. Therefore, the probability of a minor stroke or another stroke within one year reaches 20%, which is 4 ~ 5 times higher than that of ordinary people. If it is a high-risk factor, over 45 years old, it is necessary to do regular brain CT scans to track the physical condition.
ABCD2 Score (ABCD2 score) is a scale commonly used to evaluate the probability of re-stroke within 2 days in people with "transient ischemic stroke" (commonly known as mild stroke).
The highest total score is 7, the risk of another stroke greater than 6 is 8%, the risk of less than 4 is 1%, and the death probability of another stroke will increase exponentially. The Stroke Association suggests that if the score is greater than 3 or not 1 attack, you should be admitted to hospital immediately for neurological treatment.
