Introduction: Wernicke’s Encephalopathy (WE) is an uncommon neurological disorder due to thiamine deficiency. Its clinical findings are variable steering its high incidence postmortem. Seldom, thiamine deficiency is present in a clinical triad consisting of cognitive disorder, ocular abnormalities and gait ataxia. Most commonly, the clinical picture is not specific leading to late or misdiagnosis. In pregnant woman with Hyperemesis Gravidarum, incoercible vomiting and poor intake paves the path to thiamine deficiency by depleting B1 storage affecting cerebral energy homeostasis. Ergo, HG leads to neurological complications affecting maternal mortality and morbidity. Case Report: We hereby present the uncommon case of WE complicate HG in 18 weeks’ gestation primigravidae. Diagnosis relied on clinical findings as the clinical picture was typical: confusion, disorientation and memory impairment besides static and kinetic cerebellar syndrome and ophthalmological abnormalities such as unequal pupils and horizontal nystagmus. Biological findings were out of normal range as it showed electrolytes imbalance, dehydration and elevated liver and pancreatic enzymes. Imaging investigations were normal. Treatment was based on intravenous thiamine supplementation and vomiting management. Conclusion: We are a preventable neurological disorder. Prompt treatment and correct dosage in light of the appropriate guidelines enlighten the prognosis and may even lead to remission. Whereas late or non-diagnosis leads to dramatic complications such as Korsakoff’s syndrome. This article aims to raise clinician’s suspicion of WE and emphasizes the importance of preventive thiamine supplementation during pregnancies and prophylactic intravenous thiamine administration in pregnancy with Hyperemesis Gravidarum.
