ABSTRACT
BACKGROUND:
Ocular motor and vestibular manifestations of Wernicke's thiamine deficiency (WTD) are frequent and heterogeneous. Previous neuropathological and neuroimaging findings identified brainstem and cerebellar lesions responsible for these findings, however, peripheral vestibular lesions are probably uncommon in human WTD, though noted on an avian thiamine deficient study.MATERIAL:
Single case study of a WTD patient post-gastric bypass who developed ataxia, oscillopsia and nystagmus, with low serum thiamine, and increased MRI T2 signal in the thalami, but normal brainstem and cerebellum. Vestibular evaluation showed significant vestibular hyporreflexia affecting all six canals, and a chronic upbeat nystagmus, now for 14 months after WTD onset.METHODS:
Serial clinical, video head impulse, nystagmus analysis, cervical and ocular vestibular evoked responses. She is undergoing treatment with Memantine, Clonazepam and vestibular rehabilitation, and feels improvement.CONCLUSION:
This report shows a novel combination of central and peripheral vestibular findings, of relevance for diagnosis and treatment, in addition to the development of a coherent hypothesis on the ocular motor and vestibular findings in WTD.Palabras clave
