Sudden paralysis of both lower extremities

Introduction refers to a disease in which the movement of the lower extremity is completely or partially lost due to the loss or disappearance of the dysfunctional movement, and the voluntary movement is reduced or disappeared. Sudden sputum of both lower extremities is a kind of sputum. 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.

Cause

Etiology: Where the cortical motor projection area and the upper motor neuron path are damaged by the lesion, it can cause upper motor neuron spasm. Common causes are craniocerebral trauma, tumor, inflammation, cerebrovascular disease, degeneration, poisoning, and internal medicine. Certain diseases, such as diabetes, hematoporphyria, macrocytic anemia, and vitamin B12 deficiency.

Diagnosis: Different from the lesion lesions, different types of warts can be produced clinically, such as single warts, hemiplegia, paraplegia, quadriplegia (sudden paralysis of lower limbs), etc., although they have different performances, they all have the same The characteristics of the muscles are increased muscle tension, hyperreflexia, shallow reflexes disappeared, so-called joint (joint) movement and pathological reflexes, muscles do not shrink, and electrical tests have no degenerative response.

Differential diagnosis

The diagnosis should be differentiated from the following symptoms:

1. Central paralysis of the lower extremities: central paralysis of the lower extremities is a clinical manifestation of congenital hydrocephalus. When the hydrocephalus is severe and the progress is rapid, it may also appear. The symptom is repeated vomiting. Brain degeneration, brain developmental disorders, central limb spasm, especially lower limbs.

2. Lower limb muscle spasm: Lower extremity muscle spasm is a symptom of spinal cord compression.

3. Quadriplegia: Quadriplegia refers to the decline or disappearance of the free movement of the limbs.

4. Myasthenia gravis: Myasthenia gravis is an acquired autoimmune disease characterized by a neuromuscular transmission disorder. The clinical features are partial or systemic striated muscle weakness and abnormal fatigue, ie morbid fatigue, muscle weakness after activity, Better after a break, light in the morning and heavy in the evening.

5. Muscular Dystrophy: Muscular Dystrophy is a group of muscle degenerative diseases caused by genetic factors. Skeletal muscle weakness and atrophy manifested in varying degrees of distribution and speed.
