Mild cerebral atherosclerosis is not serious because people can gradually experience a loss of elasticity of blood vessels as they age, which manifests itself as vascular atherosclerosis. If mild cerebral atherosclerosis occurs in elderly patients, it is considered to be caused by age and other factors. If mild cerebral atherosclerosis occurs in young and middle-aged patients, it is recommended to find out the cause and monitor the patient’s blood glucose, blood lipids, blood pressure, and serum homocysteine, etc., so as to avoid the aggravation of cerebral atherosclerosis and the emergence of cerebral vascular diseases due to some triggers. For the examination of cerebral arteriosclerosis, it is mainly through the color ultrasound of carotid vessels, nuclear magnetic angiography or CTA examination, which can find the intima-media thickening of blood vessels. A part of serious patients can lead to the formation of malignant plaques, and if necessary, patients can be given oral statin drugs to protect the vascular lining and delay the occurrence of atherosclerosis. At the same time, the diet should be based on fresh vegetables and fruits.
