The causes of cerebral insufficiency are mainly the following: first, caused by vascular factors, if patients have diabetes, hypertension, hyperlipidemia, cerebral atherosclerosis, etc., will lead to patients with plaque in the carotid artery, which will cause changes in the cerebral hemodynamics of patients, causing symptoms of cerebral insufficiency. Secondly, it is considered to be related to cervical spondylosis, such as vertebral artery cervical spondylosis, which can lead to compression of the vertebral artery due to the misalignment of the cervical vertebrae, and cause insufficient blood supply to the brain. Thirdly, it is mainly due to the heart, which is the main factor of blood pumping. If the patient has chronic cardiac insufficiency and heart failure, the function of the heart pumping blood will be reduced, and the ejection of blood will be reduced, thus making the patient suffer from cardiogenic cerebral insufficiency.
