Vitamin B1 shortage? Vitamin B1 (thiamine diphosphate)

Vitamin B1 (thiamine diphosphate).

Vitamin B1 is a member of the family of B vitamins. B1 is found in milk and the membranes of cereal products and rice.

Deficiency causes disorders in the excitation conduction of the nerves.
A deficiency of vitamin B1 can lead to problems related to the nervous system such as depression, a lowered irritability threshold, concentration problems and memory loss. Other symptoms include muscle weakness, decreased reflexes, decreased appetite, weight loss, and stomach disorders. After supplementation with vitamin B1, most symptoms disappear, but the changes in the nervous system are permanent. Beriberi is the classic form of vitamin B1 deficiency. A severe vitamin B1 deficiency can result from chronic excessive alcohol consumption combined with a diet low in vitamin B1. The whole of the mental disorders involved (memory loss, dementia and delirium) is called the Wernicke-Korsakoff syndrome.
