Dementia due to vitamin B12 deficiency – http://id.who.int/icd/entity/1796074797

Neuropsychiatric manifestations of vitamin B12 (cobalamin) deficiency can include, cognitive impairment (mainly memory problems), personality change, psychosis, emotional lability, and rarely delirium or coma. Vitamin B12-responsive neuropsychiatric manifestations may be seen in patients without hematologic manifestations and in some patients with a low to normal vitamin B12 level. The cognitive impairment can respond to vitamin B12 administration but is variable and may relate to the duration of the deficiency.
