Paralysis

Introduction Generalized paralysis refers to a state in which the function of cells, tissues and organs of the body declines and does not respond to stimulation. Narrowly defined paralysis refers to the decline of the function of the nervous system, especially the motor nervous system. Sports paralysis can be divided into complete paralysis and incomplete paralysis according to the degree, according to the nature can be divided into central (sexual) paralysis and peripheral (slow) paralysis. Central paralysis is a disorder that is emitted from the cerebral cortex to the first neuron of the anterior horn of the spinal cord, the degenerative pathway. Peripheral paralysis is a disorder that is emitted from the anterior horn of the spinal cord to the second neuron of the skeletal muscle.

Cause

First, the cause of the disease

Where the cortical motor projection zone and the upper motor neuron pathway are damaged by the lesion, it can cause upper motor neuron spasm. Common causes are craniocerebral trauma, tumor, inflammation, cerebrovascular disease, degeneration, poisoning, and some internal medicine. Diseases such as diabetes, hematoporphyria, macrocytic anemia, and vitamin B12 deficiency.

Second, the pathogenesis

Common causes of lower motor neuron spasm are: peripheral nerve injury, such as laceration, contusion, compression, brachial plexus trauma, electric shock, radiation injury, burns, etc.; toxic damage, including drugs, organic matter, inorganic matter , bacterial toxins, etc.; peripheral neuritis, including infectious, post-infection and allergic diseases, connective tissue disease and nodular peripheral neuropathy; peripheral neuropathy in metabolic diseases; peripheral neuropathy in malignant diseases; peripheral neurological tumors, Primary and genetic related peripheral neuropathy.

an examination

Related inspection

Nervous system nuclear medicine examination vagus nerve examination nervous system examination

For patients with related neurological examinations such as knee reflexes, and found that the patient has dyskinesia, can further determine whether the patient is complete or incomplete paralysis, to further diagnose the CT scan of the brain or other parts.

Differential diagnosis

Feet and numbness: Feeling numbness, unfavorable flexion and extension, inflexible movement, "ant crawling the same" or "needle-like feeling", some patients have "socks" and "sleeve" type abnormal feeling, consciously the skin becomes thicker and feels dull . Many patients often have seizures during sleep at night, and even wake up, or their hands are numb after getting up in the morning, numbness is not stiff, and can be relieved after a little activity.
