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.
Treatment may vary by symptom, though it is common to administer thiamine (up to 40 mg/kg/day) and sometimes biotin (5-10 mg/kg/day) orally. This treatment is specifically used to address neurological symptoms and can reverse these symptoms if taken early enough.
Transketolase activity decreases due to thiamine deficiency, generally due to malnutrition. Several diseases are associated with thiamine deficiency, including beriberi , biotin-thiamine-responsive basal ganglia disease (BTBGD) , [ 5 ] Wernicke–Korsakoff syndrome , and others (see thiamine for a comprehensive listing).
Thiamine responsive megaloblastic anemia syndrome (also known as Rogers syndrome) is a very rare autosomal recessive genetic disorder affecting a thiamine transporter, which is characterized by megaloblastic anemia, diabetes mellitus, and hearing loss. The condition is treated with high doses of thiamine (vitamin B1).
Calcium and magnesium have been shown to affect the distribution of thiamine in the body and magnesium deficiency has been shown to aggravate thiamine deficiency. [22] Thiamine contents in human tissues are less than those of other species. [16] [64] The half-life of thiamine content stored in tissues of human body is about 9-18 days. [62]
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.

thiamine deficiency: neurological symptoms caused by biochemical lesions of the central nervous system after exhaustion of B-vitamin reserves, in particular thiamine: Wernicke–Korsakoff syndrome: Carl Wernicke, Sergei Korsakoff: neurology, psychiatry: Wernicke encephalopathy, Korsakoff syndrome
It mainly causes vision changes, ataxia and impaired memory. [2] The cause of the disorder is thiamine (vitamin B 1) deficiency. This can occur due to Wernicke encephalopathy, eating disorders, malnutrition, and alcohol abuse. These disorders may manifest together or separately. WKS is usually secondary to prolonged alcohol abuse.
