Most of the lacunar cerebral infarction does not affect the patient’s life expectancy, while a few more serious lacunar cerebral infarction may lead to a shorter life expectancy, such as lacunar cerebral infarction in critical areas or patients with lacunar status. Cavernous cerebral infarction refers to cerebral infarction where the diameter of the lesion is less than 1.5 centimeters, and the symptoms are usually mild, such as dizziness, weakness of one side of the limb, numbness of one side of the limb, and unfavorable speech. The clinical symptoms of patients are mild and have less impact on the quality of life, and patients can survive for a long time without significant impact on their life expectancy. Patients with lacunar state or lacunar cerebral infarction in critical areas may have relatively more severe symptoms, which may include dementia, dysphagia, choking on drinking water, etc. as well as some other complications such as lung infection, bedsores, etc., which will affect the patients’ quality of life and life expectancy. Patients with lacunar cerebral infarction may recur, so even mild lacunar cerebral infarction should not be taken lightly, and secondary prevention should be carried out in time to reduce the probability of recurrence of cerebral infarction.
