Some cases of Wernicke encephalopathy are related to appetite loss; however, the degree to which loss of appetite leads to thiamine deficiency is not known.<\/jats:p><\/jats:sec><jats:sec id=\"S1478951515000875_sec_a2\"><jats:title>Method:<\/jats:title><jats:p>A 63-year-old female with advanced cancer of the external genitalia was referred for psychiatric consultation because of disorientation, insomnia, and bizarre behaviors. Her symptoms fulfilled the diagnostic criteria for delirium. Routine laboratory examinations did not reveal the cause of the delirium. Thiamine deficiency was suspected because appetite loss had continued for 19 days since she had been admitted to hospital.<\/jats:p><\/jats:sec><jats:sec id=\"S1478951515000875_sec_a3\"><jats:title>Results:<\/jats:title><jats:p>Intravenous administration of thiamine resulted in recovery from the delirium within three days. Serum thiamine level was found to be 16 ng\/ml (normal range: 24\u201366 ng\/ml). The clinical findings, the low level of thiamine in the serum, and the effective alleviation of delirious symptoms after thiamine administration fulfilled Francis's criteria for delirium induced by thiamine deficiency.<\/jats:p><\/jats:sec><jats:sec id=\"S1478951515000875_sec_a4\"><jats:title>Significance of results:<\/jats:title><jats:p>Clinicians must be aware of the possibility of Wernicke encephalopathy in cancer patients, especially in those with loss of appetite for longer than 18 days. The degree of appetite loss in such patients might serve as a reference. Early detection and intervention may alleviate the symptoms of delirium and prevent irreversible brain damage.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s1478951515000875","type":"journal-article","created":{"date-parts":[[2015,12,11]],"date-time":"2015-12-11T05:22:31Z","timestamp":1449811351000},"page":"302-306","source":"Crossref","is-referenced-by-count":21,"title":["Early
