BACKGROUND Wernicke's encephalopathy is usually associated with alcohol abuse, but can also occur with hyperemesis gravidarum. The effect of delay in thiamine replacement on fetal outcomes is unknown. We present a case of this complication. CASE A primipara with hyperemesis was admitted for mental status changes in her 14th week of pregnancy. Physical examination revealed a lethargic patient with ophthalmoplegia, ataxia, and hyporeflexia. Parenteral thiamine therapy was started. The patient improved rapidly although the ataxia persisted. A spontaneous abortion occurred 2 weeks later. CONCLUSION Wernicke's encephalopathy can complicate hyperemesis gravidarum. Early thiamine replacement may decrease the chances of spontaneous abortion.
