Abstract

The patient was a 48-year-old woman with gait disturbance as her initial symptom. Two years after the onset of the gait disturbance, she developed motor weakness and a sensory disturbance in her limbs, and dementia. On admission to our hospital, the patient's serum vitamin B12 and folic acid levels were low, and she was found to have normochromic anemia. She also had widespread coarse hair and canities was diagnosed. The patient's paresthesia resolved in response to injection of 500 micrograms mecobalamin every other day, and the Hasegawa dementia scale score and the patient's hand grip strength improved. Her gait also improved, and she became able to walk on tiptoe. Her hair returned to normal. Supplementation with high-dose methyl B12 appeared to be effective to some extent in treating a broad range of neurologic disorders besides subacute combined degeneration of the spinal cord. In addition, the hair abnormality may be a marker of vitamin B12 deficiency.
