Wernicke-Korsakoff syndrome (WKS) is an acute neuropsychiatric syndrome caused by thiamine (vitamin B1) deficiency characterized by ocular signs, mental status changes, and ataxia [1]. Thiamine deficiency leads to brain lesions because of the impaired function of enzymes requiring thiamine pyrophosphate as a coenzyme in vulnerable regions with high thiamine content and turnover [2]. Chronic alcohol use is the most frequent condition that predisposes to thiamine deficiency [1], but WKS can also be caused by a variety of non-alcoholic precipitating illnesses. In a recent systematic review on 613 non-alcoholic WKS, most frequent precipitating illnesses were hyperemesis gravidarum in 18% of cases, dietary insufficiency or vomiting in 17%, bariatric surgery in 11%, gastrointestinal cancer in 9%, leukemia or cancer of lymphoid system in 6%, and intravenous feeding in 5% [3].

Patients with cancer are at risk of thiamine deficiency due to anorexia, vomiting, malabsorption and malnutrition,...
