The number of years you can live once a mild cerebral infarction is determined depends on the situation. Cavernous cerebral infarction and risk factors that are well controlled have no effect on life expectancy, and poorly controlled can be life-threatening. Mild cerebral infarction is relatively small in size, without clinical symptoms, the infarction is in the sensory or some dumb areas that do not show clinical symptoms, and the cerebral infarction is found only during the examination, which is cavernous cerebral infarction, and usually has no effect on the life expectancy. If the risk factors are well controlled, such as diabetes, hypertension, hyperlipidemia, etc., and there is no stenosis after examination of large blood vessels, and no more cerebral infarction, there is no difference between life expectancy and normal people. In a few cases, mild cerebral infarction may be combined with lesions of large blood vessels. Patients with lesions of large blood vessels may have life-threatening consequences if the risk factors of blood pressure, blood lipids, and blood glucose are not well controlled, and cerebral infarction in critical areas occurs again. Usually, patients should eat a light diet, take appropriate physical exercise, maintain a stable mood, avoid excessive fluctuations in blood pressure, take relevant medications on time and regularly as prescribed by the doctor, and should be monitored regularly.
