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.
Korsakoff syndrome (KS) [1] is a disorder of the central nervous system characterized by amnesia, deficits in explicit memory, and confabulation.This neurological disorder is caused by a deficiency of thiamine (vitamin B 1) in the brain, and it is typically associated with and exacerbated by the prolonged, excessive ingestion of alcohol.

Axial FLAIR MRI images represent the best diagnostic MRI sequence. Contrast material may highlight involvement of the mamillary bodies. There appears to be very little value for CT scans. [6] Thiamine can be measured using an erythrocyte transketolase activity assay, [6] or by activation by measurement of in vitro thiamine diphosphate levels. [6]
The study, which involved 106 peri- and postmenopausal women and was presented at the Endocrine Society’s annual meeting in May, indicates women should self-monitor their vasomotor symptoms and ...
Normal levels of thiamine, thiamine monophosphate, and thiamine diphosphate are commonly found, but there is a reduced or absent level of thiamine triphosphate. This is thought to be caused by a blockage in the enzyme thiamine-diphosphate kinase, and therefore treatment in some patients would be to take thiamine triphosphate daily.
Ethanol also disrupts thiamine storage in the liver and the transformation of thiamine into its active form. [23] The role of alcohol consumption in the development of WKS has been experimentally confirmed through studies in which rats were subjected to alcohol exposure and lower levels of thiamine through a low-thiamine diet. [24]
Alcohol, a carbohydrate, increases the metabolic demand for thiamine (vitamin B1) because of its role in the metabolism of glucose. Thiamine levels are usually low in alcoholics due to their decreased nutritional intake. In addition, alcohol interferes with intestinal absorption of thiamine, thereby further decreasing thiamine levels in the ...
"Low self-confidence can lead to increased stress levels, depression, anxiety, poor boundaries, people-pleasing and substance use," says Dr. Melissa Boudin, PsyD, a licensed psychologist with ...
