Beriberi Neuropathy Mimicking Guillian-Barre Syndrome in a Teenager With Food Restriction: A Case Report.

Cureus 2022 Jan 19;14(1):e21417. Epub 2022 Jan 19.

Child Neurology and Neurodevelopmental Disabilities, West Virginia University Medicine, Morgantown, USA.

Beriberi neuropathy (thiamine deficiency) and Guillian-Barre Syndrome (GBS) both can present with areflexia and progressive ascending weakness. A physical examination can be equivocal between the two. In cases where GBS is suspected clinically but initial work-up with cerebral spinal fluid (CSF) studies and magnetic resonance imaging (MRI) of the spine are not diagnostic, nerve conduction study/electromyography (NCS/EMG) should be done to evaluate beriberi neuropathy.

[Wernicke-Korsakoff syndrome and other diseases associated with thyamine deficiency].

Med Clin (Barc) 2022 05 14;158(9):431-436. Epub 2022 Jan 14.

Servicio de Medicina Interna, Hospital Universitario de Salamanca-IBSAL, Universidad de Salamanca, Salamanca, España. Electronic address:

Wernicke-Korsakoff syndrome is the best known consequence of thiamine deficiency, frequently associated with patients with chronic and excessive alcohol consumption, but it can be produced by any cause that produces thiamine deficiency. The disease is underdiagnosed so it is essential to have a high clinical suspicion, mainly in patients who do not have alcohol consumption as a risk factor. For this, the diagnosis continues to be eminently clinical, with the difficulty of high clinical variability. Read More

Thiamine deficiency in Gambian women of reproductive age.

Ann N Y Acad Sci 2022 01 20;1507(1):162-170. Epub 2021 Sep 20.

MRC Unit The Gambia at London School of Hygiene & Tropical Medicine, Banjul, The Gambia.

Thiamine deficiency disorders are associated with a variety of clinical symptoms affecting the nervous and cardiovascular systems. There is growing recognition that thiamine deficiency can occur in populations well beyond the classical region of South Asia, and at-risk populations include those who receive a large proportion of their energy from polished white rice (or other low-thiamine staple foods) and with low dietary diversity. Reports of thiamine deficiency in West Africa over the last century have suggested that this has historically been an issue in this population, but in more recent decades, these reports have been limited to prison populations.

Institute for Global Nutrition University of California Davis Davis CA USA.

Infantile beriberi, a potentially fatal disorder caused by thiamine deficiency, is often viewed as a disease confined to history in regions of the world with predominant white rice consumption. Recent case reports have, however, highlighted the persistence of thiamine deficiency as a cause of infant mortality in South and Southeast Asia. Low infant thiamine status and incidence of beriberi is attributable to maternal thiamine deficiency and insufficient breast milk thiamine. Read More
