Spinal cord subacute degeneration in the elderly

Subacute degeneration of spinal cord is a degenerative disease of the nervous system caused by vitamin B12 deficiency, which usually occurs with malignant anemia. The main lesions are the posterior and lateral cords of the spinal cord. The clinical manifestations are deep sensory dysfunction, sensory ataxia, and spastic paralysis, accompanied by peripheral sensory dysfunction. Some scholars believe that the damage of the disease is not limited to the spinal cord, but can also occur in the optic nerve and cerebral hemisphere. In addition, the damage to the spinal cord is not limited to the conductive tract system of the posterior and lateral cords. The white matter of the spinal cord can be affected.
