The brain retains its thiamine content in the face of a vitamin-deficient diet with great tenacity, as it is the last of all nervous tissues studied to become depleted. Lack of thiamin causes the disease known as beriberi. There are two forms of beriberi: ""wet"", and ""dry"". Dry beriberi is also known as cerebral beriberi and characterized by peripheral neuropathy. Thiamine deficiency has been reported in up to 80% of alcoholic patients due to inadequate nutritional intake, reduced absorption, and impaired utilization of thiamine."

First seen in 1642 by the Dutch physician Jacobus Bontius, it was named for the Cingalese word meaning weakness-weakness. Beriberi is seen in two forms: wet and dry. When in the dry form the patient experience pains in their extremities, paresthesias, paralyses, and contractures due to being a paralytic type of disease. When"

He suspected the disease was caused by an unknown bacteria. Eijkman was unable to continue his research due to ill health, but a study by his friend Adolphe Vorderman confirmed the link between polished rice and the disease. Eventually it was determined the missing compound that was causing Beriberi was vitamin B, thiamine. Chemist Casimir Funk shortened the term ""vital amine"" to coin a new word, vitamin.

It remains relatively common in sub-Saharan Africa. Outbreaks have been seen in refugee camps. Thiamine deficiency has been described for thousands of years in Asia and became more common in the late 1800s with the increased processing of rice.

As a result, it is likely that the deaths of Burke and Wills resulted in part from a vitamin deficiency disease called beriberi. Evidence to this effect is further provided by King's account, which revealed that Burke complained of leg and back pain shortly before his death.

Characteristics of wet beriberi include prominent edema and cardiac involvement, whereas dry beriberi is mainly characterized by a polyneuritis. Severe thiamin deficiency can also result in acute neurodegeneration leading to peripheral neuropathy and memory loss. In industrialized nations, thiamine deficiency is a clinically significant problem in individuals with chronic alcoholism or other disorders that interfere with normal ingestion of food.

Chronic alcoholism can disrupt thiamin absorption and thiamin deficiency contributes to neurodegeneration and memory loss in alcoholics known as"
