The length of life of patients with cerebral ischemic foci cannot be generalized and is closely related to the location and size of the lesion. In fact, cerebral ischemic focus is not an isolated disease, it may be caused by cerebral embolism, cerebral thrombosis, lacunar cerebral infarction and other diseases. Generally speaking, if the cerebral ischemic focus is small and treated in a timely manner, patients can usually recover within a short time and will not affect their normal life expectancy. However, if the site of cerebral ischemic foci is critical, such as occurring in the brainstem, or the area of ischemic foci is relatively large, the damage to brain tissue is more serious, and the treatment effect is not ideal, it may shorten the patient’s normal life expectancy and even sudden death, it is recommended that the patient must go to the hospital in time to improve the relevant examination, clarify the specific cause, and actively give targeted treatment to reduce the occurrence of adverse conditions. In addition, after active treatment, regular follow-up visits to the neurology department of the hospital should be strictly followed in order to observe changes in the condition and to treat it at any time.
