Wernicke Encephalopathy in a Patient of Acute Gastroenteritis: A Case Report

An acute neurological disease known as Wernicke Encephalopathy (WE) is characterised by the clinical triad of symptoms: ophthalmoparesis with nystagmus, ataxia, and disorientation. Thiamine deficiency is the underlying cause of this potentially fatal condition, which mainly affects the central and peripheral nervous systems. Hereby, the authors present a case of a 47-year-old male who presented with multiple episodes of loose stools and altered consciousness to the emergency ward. He had hyperchloremic metabolic acidosis suspected to be due to acute gastroenteritis, which may have caused his altered consciousness. Despite correction of his metabolic acidosis, his sensorium did not improve. Later, he was diagnosed with WE using Magnetic Resonance Imaging (MRI) brain findings, which showed symmetrical subtle hyperintensities in the medial part of the thalami and periaqueductal grey matter, suggestive of WE; his consciousness improved after thiamine supplementation. There should be a high suspicion of WE for timely diagnosis and treatment. Prompt treatment would be rewarding as WE is reversible, if treated in time.
