Symptoms of insufficient blood supply, common manifestations of insufficient blood supply to the brain

Insufficient blood supply to the brain can lead to brain dysfunction. The most common cause of insufficient blood supply to the brain is cerebral arteriosclerosis. Early symptoms should be taken seriously. Generally, there will be crooked mouth, difficulty speaking and swallowing, and always being unable to wake up. Timely diagnosis and treatment are required.

1. Early clinical manifestations

Cerebral ischemia refers to a disease in which various reasons lead to chronic and widespread blood supply deficiency in the brain, causing cerebral ischemia and hypoxia, resulting in a series of clinical manifestations of brain dysfunction. The clinical manifestations of cerebral ischemia are as follows:

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

4. 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.
