Cerebral ischemic foci do not heal themselves. Cerebral ischemic foci is not a medical diagnosis, it is not a disease name, it is an imaging sign found by imaging. The extreme majority are atherosclerosis-related, that is, secondary changes in the cerebral vasculature as a result of systemic atherosclerosis caused by long-term hypertension, hyperlipidemia, and diabetes mellitus. Acute stenosis of small vessels deep within the brain often triggers small cavernous infarcts, whereas chronic stenosis, with prolonged inadequate blood supply, results in ischemic foci. If not effectively controlled, they usually increase in number and become more and more numerous and do not heal on their own. It is necessary to cooperate with professional neurologists for risk factor control, such as controlling blood pressure, blood sugar, smoking cessation, etc. Secondary preventive medication, such as aspirin, Revastatin, etc., is needed if necessary to avoid the ischemic foci from continuing to increase or growing in size. Once the examination found cerebral ischemic foci, it is recommended to consult a professional physician in a timely manner and intervene under the guidance of the physician, do not blindly self-medication.
