“Cavernous infarction, commonly known as lacunar cerebral infarction, is a common type of stroke. “Patients with lacunar infarction often do not have obvious symptoms, such as mild headache, dizziness, memory loss, slow reaction time, forgetfulness, blurred vision and facial numbness. Figure A shows multiple old infarcts on MRI; Figure B shows acute infarcts on MRI. Although patients with “Cavitary infarction” may not have any symptoms, and most of them only find “Cavitary infarction” by chance during CT and MRI. However, it is important not to ignore these abnormal signs just because there are no symptoms. Because the detection of “cavernous infarction” indicates the existence of atherosclerosis of blood vessels in the brain, we know that there are very rich blood vessels in the brain supplying the necessary nutrients to the brain, once these blood vessels are hardened and further occluded, the brain will be deprived of the nutrient supply, which will lead to neurological dysfunction. Moreover, “cavernous infarction” can recur, and each attack will aggravate the neurological dysfunction, resulting in a cumulative effect. Therefore, in the clinic, it is often seen that after repeated attacks of “Cavity infarction”, the neurological function is seriously regressed, and intellectual decline or even dementia occurs, which brings a heavy burden to the patient’s family. Therefore, it is very important to prevent the onset of “Cavitary Infarction”, especially repeated attacks. We know that “cerebral infarction” mainly develops on the basis of high blood pressure and arteriosclerosis, so the first thing we need to do is to monitor the blood pressure on a regular basis, and for patients who are clearly diagnosed with hypertension, they need to take antihypertensive medication regularly to keep their blood pressure within the normal range, so as not to aggravate arteriosclerosis, which may lead to the occlusion of important blood vessels in the brain. In addition, diabetes mellitus, hyperlipidemia, smoking and alcoholism are also high-risk factors for cavernous infarction, therefore, active treatment of diabetes mellitus, hyperlipidemia, smoking cessation and alcohol restriction can help prevent cavernous infarction. Summary Do not ignore “cavity infarction”, actively improve the lifestyle, control risk factors, is the key to prevent the development of “cavity infarction”: 1, control hypertension, prevent atherosclerosis is the key to prevent “cavity infarction”. Control of hypertension and prevention of atherosclerosis is the key to preventing “caval infarction”. 2.Actively treating diabetes, hyperlipidemia, quitting smoking and limiting alcohol, and controlling and managing these risk factors. 3, can choose some drugs to improve blood circulation in the brain, increase the blood supply to the brain, is helpful to promote the recovery of nerve function. 4, the new headache, dizziness, memory loss, slow reaction, forgetfulness, blurred vision, facial numbness and other symptoms, we should go to the hospital as soon as possible, through the imaging examination, such as cranial CT and nuclear magnetism, etc., as soon as possible to clarify the diagnosis, and actively prevention and treatment.
