What are the symptoms of insufficient blood supply to the head

Insufficient blood supply to the head means insufficient blood supply to the brain, which mainly refers to the insufficient blood supply to a certain part of the human brain, affecting brain function. There are many reasons for insufficient blood supply to the brain. The occurrence of this disease is often closely related to cerebral arteriosclerosis. Because the disease is very harmful, we must understand the symptoms and provide timely treatment when it is discovered. So, what are the symptoms of insufficient blood supply to the head? Let’s take a closer look at it below.

Clinical manifestations

1. Abnormal mental consciousness

If you always feel sleepy and feel groggy all day long, it is not caused by excessive fatigue, but a precursor sign of insufficient blood supply to the brain. Some people also experience insomnia, some have some changes in personality, such as being lonely, taciturn or indifferent, some are talkative and irritable; some may experience brief loss of consciousness or intellectual decline, or even loss of normal judgment, all of which are related to insufficient blood supply to the brain.

2. Motor nerve dysfunction

This type of premonitory symptom is the most common. Due to insufficient blood supply to the brain, the nerves controlling the body's motor functions malfunction. Common manifestations include sudden crooked mouth, drooling, difficulty speaking, slurred speech, aphasia or inarticulate speech, difficulty swallowing, weakness or poor movement of one limb, dropping of held objects, unsteady walking or sudden falls, and some people experience limb spasms or twitching.

3. Sensory dysfunction

Due to insufficient blood supply to the brain, the analytical areas, sensory organs and sensory nerve fibers of the brain are affected, often manifesting as numbness of the face, tongue, lips, and one side of the limbs or a foreign body sensation; some have blurred vision or even sudden temporary blindness; many people have sudden dizziness; some have spontaneous limb pain; others suddenly experience tinnitus, hearing loss, etc.

treat

1. Remove risk factors

Such as treating high blood pressure, quitting smoking, and prohibiting excessive drinking.

2. Antiplatelet drugs

Aspirin, an antiplatelet drug, is the first choice. It can effectively prevent platelets from clumping together, which is good for blood circulation and blood supply to the brain.

3. Anticoagulant drugs

Anticoagulants and antiplatelet drugs have the same effect, both of which can improve blood flow, increase blood supply to the brain, and reduce the incidence of cerebral ischemia.

4. Surgery

If the carotid artery is severely narrowed (more than 70%), carotid endarterectomy or carotid stenting can be used if necessary.
