Beri Beri

Beri beri is a disorder of nervous system which is actually cause by the deficiency of the thiamine(deficiency of vitamin B1) in the diet of the individual, thiamine is basically found in the membranes of neurons and it is involved in the break down of the energy molecules such as glucose. Beriberi may be found in people whose diet consists mainly of polished white rice, which is very low in thiamine because the thiamin-bearing husk has been removed. It can also be seen in chronic alcoholics (Wernicke-Korsakoff syndrome), Arsenic poisoning causes alterations in cellular metabolism resulting in blockage of thiamine use which results in thiamine deficiency without any dietary shortfall. The mechanism of arsenic neuropathy may be similar to the neuropathy of thiamine deficiency [Sexton and Gowdy 1963], whereby arsenic inhibits the conversion of pyruvate to acetyl coenzyme A and thus blocks the Krebs cycle.
