Stroke primarily refers to cerebrovascular disease, characterized by the sudden onset of symptoms that develop within minutes. This rapid development of symptoms is why it is called a stroke. Stroke commonly affects middle-aged and elderly people who often have certain risk factors. For example, high blood pressure, high blood cholesterol, smoking, drinking, obesity, and heart diseases like atrial fibrillation can increase the risk of stroke. For the treatment of stroke, it is crucial to reach the hospital as soon as possible, as earlier treatment leads to better outcomes. Generally, if it is suitable, the patient may receive intravenous thrombolysis. Additionally, treatment may involve anti-atherosclerosis measures, nutritional support for nerves, and rehabilitation training, which is also very important.
