Serum vitamin B12 levels decreased, serum anti gastric parietal cell antibodies and anti-intrinsic factor antibodies were positive. Blood analysis showed macrocytic anemia, neuropsychological scale showed functional impairment in multiple cognitive domains, electrophysiological examination showed peripheral nerve damage, cerebrospinal fluid and imaging examination showed no abnormalities. The patient was diagnosed as having vitamin B12 deficiency dementia, vitamin B12 deficiency related involuntary movement and pernicious anemia.
