Darkness in the eyes and numbness in the mouth are signs of insufficient blood supply to the brain. It may be caused by low blood pressure, slow heartbeat, or an acute stroke.
Darkness in the eyes may be a sign of insufficient blood supply to the whole brain, or insufficient blood supply to the ophthalmic artery, or damage to the ophthalmic nerve; numbness of the mouth is a problem with the sensory function of the trigeminal nerve, which may be the trigeminal nerve, or its superior trigeminal nucleus, the cortical brainstem bundle, or the sensory center of the brain has undergone lesions.
The most likely cause of black eyes and numbness in the mouth at the same time is an obstruction of blood supply to the whole brain. Similar symptoms may occur when the cardiovascular system is affected by the blood supply to the brain, such as low blood pressure, a slow heartbeat, or an acute myocardial infarction that affects the heart’s ability to pump blood.
In addition, acute cerebral hemorrhage or cerebral infarction induced by vascular disease in the brain may lead to similar symptoms. However, stroke is often accompanied by hemiplegia on one side of the body, numbness of the limbs, slurred speech, difficulty in swallowing and other symptoms.
It is recommended that patients go to the hospital as soon as possible, complete the head CT and other examinations to clarify the cause, and carry out treatment under the guidance of the doctor.
