Stroke is unpreventable because there are still triggers that have not yet been recognized. The following symptoms are unfamiliar signs of stroke. 1, more sleep more sleep is also known as sleepy. The light one is tired and sleepy, sleepy after eating, and sometimes sleepy; the heavy one is sleepy around the day and night or sleepy after waking up. According to analysis, the majority of sleepiness in the elderly is closely related to stroke. Unlike other stroke omens, excessive sleepiness appears earlier, with symptoms occurring 6 months to 1 year before the stroke, therefore, if treatment is given early in conjunction with blood viscosity, lipids, blood pressure and other test results, it is possible to prevent the problem before it happens. 2, depression American medical doctors found that mental depression can increase the risk of stroke for the first time in men by 58% and in women by 85%. The reason is that depression makes the immune system’s ability to prevent and fight disease “slippery”, platelet cohesion is enhanced, easy to induce infarction. If you can promptly treat depression and take anti-coagulant drugs, you can reduce the risk of stroke. 3, inflammation Experts point out that the high incidence of stroke in winter and spring may be related to the increase in infections in this season. Therefore, it is recommended to strengthen the prevention and treatment of infectious diseases, as well as taking drugs that help eliminate the inflammatory response of blood vessels and have an anticoagulant effect, such as aspirin. 4, tongue pain Elderly people with no obvious reason for tongue pain, mostly microvascular inflammatory reaction, may also be related to the increase in blood viscosity. Therefore, if elderly people have tongue pain, numbness and difficulty in moving, they should not only pay attention to the local area, but also have a systemic examination and take drugs according to the situation to prevent stroke. 5. Snoring Especially the increasingly serious snoring that has appeared in the past six months, “beating to death”, even with apnea, is an important factor causing stroke. Therefore, it is suggested that severe snoring should be regarded as a precursor of stroke, and early treatment should be carried out, and drugs to improve cerebrovascular function should be taken at the same time. 6. Swallowing paralysis Occasional choking on drinking water, discomfort in the pharynx, and a feeling of food residue and unfavorable swallowing when swallowing food. This may be a stroke sensory loss caused by damage to the pharyngeal nerve. Research shows that this paralysis is likely to be a precursor to stroke, if early and reasonable use of drugs, not only conducive to the treatment of swallowing paralysis, but also may prevent sudden onset of stroke.
