Acute cerebrovascular disease, commonly known as “stroke”, has a high mortality and disability rate once it occurs. The most common cause of cerebrovascular disease is atherosclerosis, which is the aging of blood vessels, and is an aging lesion. Usually young children do not have strokes, but the likelihood of stroke increases with age. Once a stroke occurs, there is no very specific treatment and it often leads to disability or even life threatening. Therefore, prevention is more important for strokes. As we age, blood vessels are aging every day. Therefore, stroke prevention requires daily medication. If there is an effective treatment after a stroke, we don’t need to use medication every day to prevent it, just treat it after it happens. It is because the treatment after a stroke is not effective. Therefore, we must pay great attention to the prevention of stroke! Atherosclerosis is the most common cause of cerebrovascular disease, and aging can lead to atherosclerosis. Therefore, everyone’s arteries will age to varying degrees by a certain age. Other common causes of atherosclerosis are: high blood pressure, dyslipidemia, diabetes, smoking, alcohol consumption, obesity, severe snoring, sedentary lack of exercise, etc.
