Both cerebral infarction and cerebral hemorrhage are prone to recurrence, but the recurrence rate of cerebral infarction is relatively higher. Cerebral infarction refers to limited ischemic necrosis or softening of brain tissue. Although timely treatment may lead to cure, there are many risk factors for cerebral infarction, such as diabetes mellitus, high blood pressure, alcoholism, smoking, and high blood lipids, etc., and cerebral infarction may still recur if these risk factors are not removed. Cerebral hemorrhage refers to non-traumatic bleeding within the brain parenchyma, which is mostly related to cardiovascular and cerebrovascular diseases, such as hypertension, aneurysm, etc. It may also be related to poor lifestyle, such as smoking, alcohol abuse, obesity, etc., which may also be prone to recurrence if the primary disease or risk factors cannot be removed. The recurrence rate of cerebral infarction is relatively higher because cerebral infarction is mainly caused by the narrowing and blockage of blood vessels. After the occurrence of cerebral infarction, the narrowing of blood vessels usually cannot disappear completely even after treatment. As long as the stenosis further aggravates, it will cause recurrence. Whether it is cerebral infarction or cerebral hemorrhage, it is still necessary to control the disease-causing factors after treatment and to have regular checkups in order to reduce the probability of the disease occurring.
