Highlights & Basics
- Vitamin B1 (thiamine) deficiency is the underlying cause of several clinical syndromes, including Wernicke encephalopathy, wet beriberi, and dry beriberi, rather than a single clinical condition or diagnosis.
- Clinical presentation depends on the chronicity of the deficiency.
- As signs and symptoms are nonspecific, the presence of risk factors raises suspicion of the diagnosis.
- Risk factors include alcohol dependence, malabsorption, and a diet low in thiamine (e.g., based on polished rice).
- As there is no rapid diagnostic test for the condition, presumptive treatment should be commenced immediately if vitamin B1 deficiency is suspected.
