Multiple ischemic foci in the brain, which are generally not serious in patients, are a manifestation of cerebral atherosclerosis and occur mostly in middle-aged and elderly people over the age of 50. In the case of elderly patients, multiple cerebral ischemic foci are generally related to cerebral atherosclerosis, which leads to hardening of the cerebral arteries, especially the hardening of small blood vessels is more obvious, easily forming multiple ischemic foci formation in the brain. In the case of young patients, it may be caused by heart diseases, such as unclosed cardiac foramen ovale, which leads to the formation of microemboli in the patient’s body, resulting in the formation of ischemic foci in the brain; or the formation of ischemic foci in the brain due to prolonged late night, poor sleep quality, migraine headaches and other conditions. Patients with multiple cerebral ischemic foci should not be overly concerned, but should actively search for pathogenic factors, monitor blood pressure and blood sugar changes, adjust the diet structure, suggest a low-salt, low-fat diet, quit smoking and alcohol, and may be given relevant drug intervention therapy.
