Cerebral infarction in the elderly is a more serious clinical condition that can lead to paralysis or even death and post-stroke depression. Cerebral infarction is divided into cerebral thrombosis and cerebral embolism in Western medicine, and the risk factors for both diseases are hypertension, diabetes, hyperlipidemia, hyperhomocysteinemia, obesity, smoking, and asymptomatic bilateral carotid artery stenosis. When elderly people have these risk factors, they must actively treat the original disease and control their risk factors. Attention must be paid to diet and living, so that they do not get a cerebral infarction and be paralyzed in bed and then pay attention to it. Therefore, cerebral infarction in the elderly is a serious clinical disease, which must be nipped in the bud when it is not onset, and if their primary disease is well treated and risk factors are well controlled, cerebral infarction disease will not occur.
