The survival time of patients with cerebral atherosclerosis varies from person to person, taking into account the specific situation, whether it is combined with other diseases, such as hypertension, diabetes, hyperlipidemia, etc., and also closely related to age, genetics, and time of onset. Patients need a comprehensive examination to assess the carotid and vertebral artery systems, and whether there are any intracranial stenoses, such as cerebral artery atherosclerosis with more plaques and predominantly unstable plaques, and multiple stenoses of intracranial vessels, a condition that can affect life expectancy if secondary brain hemorrhage or cerebral infarction is more severe. The early or late appearance of atherosclerosis is closely related to the patient’s age, whether other diseases are complicated, genetics, etc. Strictly speaking, patients with simple cerebral atherosclerosis who have not progressed to cerebral infarction or cerebral hemorrhage generally do not have an impact on life expectancy. Patients with cerebral atherosclerosis should actively control related risk factors, such as hypertension and diabetes, to slow down the progression of atherosclerosis.
