Various types of sports neuron disease

Sports neuron disease can be divided into four types

Myocytreatry side rigidation is the most common type of motor neuronal disease. The clinical manifestations of asymmetrical muscle weakness and muscle atrophy began from the far end of the limb, and patients finally died of respiratory muscles or concurrent respiratory infections, and the survival shortcomings were several months, and the elder were more than 10 years. Most of them have been in the age of 50, and the ratio of men and women is 2: 1,90% is a distributed case.

Performing myocardial shrinking is pure exercise neuron involvement, PMA is slowly progressed, the disease is longer, and some patient survival can reach 15 to 25 years or even longer, and the late patient can have a systemic muscle weakness and muscle atrophy. If there is a marrow Paralysis is shorter, often died of respiratory muscles or lung infections.

Performing delays is the intravation of the brain stem, non-accumulated and spinal cord in front corner, clinical, clinical, can be expressed as the weakness and shrinking of the mandibular muscle, myopathy, tongue muscle and throat muscle. PBP is usually developed rapidly than other types of motion neuron diseases, and patients have died of malnutrition, respiratory muscle paralysis and secondary lung infection due to poor swallowing difficulties and can't drink water. Clinically, simple PBP is rare, many patients gradually accumulate limbs after 1 to 2 years, transformed into ALS.

Primary lateral risar hardening is pure sports neuron involvement, clinically rare, expressed as being carprocect paraplegic or tipples, and gradually emerges in upper limbs and throat muscles. This type is slow, and the patient can survive longer.
