Chris 大二下 (2020/06/01):

Subacute combined degeneration — Deficiency in vitamin B12 (cobalamin) leads to degeneration of the dorsal and lateral white matter of the spinal cord, producing a slowly progressive weakness, sensory ataxia, and paresthesias, and ultimately spasticity, paraplegia, and incontinence. Not all patients with neurologic abnormalities will have anemia or macrocytosis. Supplemental treatment with vitamin B12 can stop progression and will produce neurologic improvement in most patients
