Vestibular Signs of Thiamine Deficiency during the Early Phase of Suspected Wernickes Encephalopathy

Non-encephalopathic presentations of central nervous system thiamine deficiency may be difficult to diagnose. Vestibular findings in the pre-encephalopathy phase, despite their potential value to assist early diagnosis and enable early treatment before severe neurologic morbidity occurs, are not widely known. We describe neuro-otologic findings of Wernickes syndrome in five patients with vestibular manifestations
