Multiple lacunar cerebral infarction is an intracranial change of ischemic nature, a change of nerve necrosis, but because in this case the ischemic range is small, like a kind of starry dot-like change, multiple dot-like foci of infarction can be seen in the skull, therefore it is called multiple lacunar cerebral infarction, commonly known as an ischemic pre-existing manifestation. Most often seen at the time of physical examination or without any clinical symptoms, if such changes are found, it signals the need for further cerebrovascular conditioning, as well as further examination to clarify the intracranial vascular changes, whether there are large artery stenosis and occlusive changes, and whether a series of lipid regulating and circulation improving treatments are needed. Therefore, once this cerebral infarction occurs, we must improve the examination, and if there is an improvement of related diseases, we must carry out medication and food, and even changes in living habits, such as actively controlling blood pressure, stabilizing blood sugar, quitting smoking, quitting alcohol, adding aspirin to lower lipids if necessary, and a series of treatments.
