Wernicke’s encephalopathy occurs due to thiamine (vitamin B1) deficiency which is characterized by occulomotor dysfunction, confusion and ataxia. Although it is most common with alcoholism, can also be seen due to hyperemesis caused by chemotherapy, Crohn’s disease, gastrointestinal system surgery, AIDS, bariatric surgery and longterm feeding with parenteral nutrition. In this case, a 51-year-old woman who was treated with longterm total parenteral nutrition due to hyperemesis and had the diagnosis of Wernicke’s encephalopathy after admission to the intensive care unit is presented.
