Peripheral neuropathy due to vitamin B12 deficiency – http://id.who.int/icd/entity/1208622375

This peripheral neuropathy may affect sensory and/or motor function. Patients usually present with symmetrical distal sensory symptoms and signs usually beginning in the feet, spreading to the hands, and accompanied by varying degrees of ataxia. The commonest neurological signs are diminished vibration sense and proprioception in the legs and can include impaired distal cutaneous sensation. These symptoms may also occur in myelopathy of the same etiology. The vitamin B12 deficiency (cobalamin deficiency) is particularly common in the elderly and is most likely due to the high incidence of food-cobalamin malabsorption associated to atrophic gastritis.
