I feel dizzy, nauseous and want to vomit when I move my head

If there is insufficient blood supply to the brain, the body's mental state will become sluggish first, and the head will feel groggy every day. Sometimes memory loss and forgetfulness may occur. In severe cases, facial paralysis or even cerebral infarction and death may occur. Once you discover this situation, you must actively go to the hospital for examination and cooperate with the doctor for treatment.

Cerebral ischemia refers to insufficient blood supply to a certain part of the brain, which causes brain function disorders. The causes of insufficient blood supply to the brain are often related to cerebral arteriosclerosis.

The incidence of cerebral ischemia is high. According to statistics, 80% of people over 80 years old suffer from cerebral ischemia, and 70% of people over 60 years old suffer from cerebral ischemia to varying degrees. The main symptoms are recurrent dizziness, lightheadedness, and headaches, often accompanied by restlessness, tinnitus, irritability, insomnia, memory loss, inattention, and forgetfulness. Studies have shown that if insufficient blood supply to the brain is not treated promptly, it may cause cerebral infarction or even dementia.

Causes

1. Dislocation of the atlantoaxial joint and C5 and C6 joints of the cervical vertebrae stimulates the vertebral artery, causing stenosis of the arterial lumen or vasospasm, reducing the blood flow and causing insufficient blood supply to the supplied brain area.

2. Hemodynamic disorder: when blood pressure drops and cardiac output decreases, the brain tissue is not supplied with enough blood.

3. Increased blood viscosity, slow blood flow and changes in blood components caused by certain reasons may also cause insufficient blood supply.

4. Microthrombosis. Microthrombosis is the detachment of atherosclerotic plaques, which form microemboli in the blood flow. They flow to the small arteries and block the blood vessels, resulting in local blood supply deficiency in the brain.

Classification

Clinically, cerebral ischemia is divided into acute and chronic. Acute cerebral ischemia (acute cerebral ischemia) is a common disease among the elderly and has been given more attention clinically, while chronic cerebral ischemia rarely attracts people's attention.

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.
