Thiamine deficiency is a medical condition of low levels of thiamine (vitamin B 1). [1] A severe and chronic form is known as beriberi. [1] [7] The name beriberi was possibly borrowed in the 18th century from the Sinhalese phrase බැරි බැරි (bæri bæri, “I cannot, I cannot”), owing to the weakness caused by the condition.

The enzymes that are dependent on thiamine pyrophosphate are associated with the citric acid cycle (also known as the Krebs cycle), and catalyze the oxidation of pyruvate, α-ketoglutarate and branched chain amino acids. Thus, anything that encourages glucose metabolism will exacerbate an existing clinical or sub-clinical thiamine deficiency. [15]
In addition, moderate deficiency of thiamine may increase rates of depression, dementia, falls, and fractures in old age. [ 106 ] The lingering symptoms of neuropathy associated with cerebral beriberi are known as Korsakoff's syndrome , or the chronic phase of Wernicke-Korsakoff's. [ 109 ]
Thiamine deficiency and errors of thiamine metabolism are believed to be the primary cause of Wernicke encephalopathy. Thiamine, also called B 1, helps to break down glucose. Specifically, it acts as an essential coenzyme to the TCA cycle and the pentose phosphate shunt. Thiamine is first metabolised to its more active form, thiamine ...
