What's wrong with my hands being unable to hold on?

When you cannot grab things with your hands, the most common phenomenon is cerebral infarction or cerebral hemorrhage. Once your brain is damaged, your brain's regulatory function will be destroyed. At this time, you will not be able to use your body organs normally, and your limbs will not be controlled by the brain. This will lead to what we call wanting to grab things but not being able to, and your hands will not obey you.

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.

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 in 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 a loner, 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.
