The average person does not have a cavernous infarction. Cavity infarcts, which also become lacunar cerebral infarcts, are related to underlying conditions such as high blood pressure and diabetes. Most patients with lacunar cerebral infarction have diabetes and high blood pressure, not everyone. Cavernous cerebral infarction is mainly due to the occurrence of vitellosis or atherosclerosis of small arteries of deep penetrating branches of the brain on the basis of long-term hypertension and diabetes mellitus, the gradual occlusion of the lumen of blood vessels, the interruption of cerebral blood flow, ischemia and hypoxia of the brain tissues, which leads to the softening of brain tissues and necrosis. Generally, the symptoms of lacunar cerebral infarction are relatively mild, and some patients do not have obvious symptoms, and the diagnosis can be confirmed by head CT or MRI. After the onset of this disease, under the guidance of the doctor’s interview, complete the auxiliary examination, clarify the cause of the disease, and actively cooperate with the doctor to deal with it.
