The majority of multiple lacunar infarcts are old lacunar infarcts with no clinical symptoms and do not require hospitalization. If the infarction is new-onset, hospitalization is required. 1. Obsolete cavernous infarction: If the multiple cavernous infarction is caused by old lesions, the infarction foci are relatively small and usually have no obvious clinical symptoms, which are often detected in CT or cranial MRI, and the condition is relatively mild, with very little impact on the brain tissues, so there is no need for hospitalization. 2. New-onset lacunar infarction: If the new-onset infarction foci cause multiple lacunar cerebral infarction, there is also a risk of progression of the disease, which may lead to mental disorders, cognitive disorders, swallowing disorders, etc., and even hemiparesis, which requires hospitalization. Whether hospitalization is needed for multiple lacunar cerebral infarction is recommended to be decided according to the time of formation of infarct foci, the presence or absence of clinical symptoms, etc., combined with the diagnosis and treatment advice of professional doctors.
