We previously demonstrated that yokukansan ameliorated not only learning disturbance but also behavioral and psychological symptoms of dementia-like behaviors (anxiety, aggressiveness) and neurological symptoms (opisthotonus) induced in rats by dietary thiamine deficiency (TD). In the present study,
We compared the thiamine and thiamine phosphate contents in the frontal, temporal, parietal, and occipital cortex of six patients with frontal lobe degeneration of the non-Alzheimer's type (FNAD) or frontotemporal dementia with five age-, postmortem delay-, and agonal status-matched control
Thiamine (Vitamin B1) is a co-factor for enzymes key in bridging aerobic and anaerobic metabolism. One such enzyme, transketolase, catalyzes two of three reactions for entry into the pentose-phosphate pathway, a major source of chemical reducing power. Thus, thiamine deprivation (TD) is considered a
Chronic alcohol consumption is frequently accompanied by cerebellar degeneration. The exact aetiology of alcoholic cerebellar degeneration is still a matter of debate. The aim of the present study was to investigate whether patients with chronic alcohol consumption exhibit a decrease in dentate
BACKGROUND
Wernicke's encephalopathy-Korsakoff syndrome (WE-KS) is common in alcoholics, caused by thiamine deficiency (TD; vitamin B1) and associated with lesions to the thalamus (THAL). Although TD alone can cause WE, the high incidence in alcoholism suggests that TD and ethanol (EtOH)
CT brain scans of 65 alcohol-dependent inpatients were compared before and after 6 weeks of confirmed abstinence. Linear measurements revealed a significant reduction of the enlargement of the ventricular system in accordance with the re-expansion of the brain after alcohol abstinence (ANOVA,
"Shoshin beriberi", which is a fulminant form of cardiovascular beriberi accompanied by hemodynamic deterioration with high cardiac output and decreased systemic blood pressure, caused by thiamine deficiency due to alcoholic abuse or malnutrition, is often difficult to address because of its rarity
Hyaline degeneration, myofiber fragmentation, and mineralization were present in the left ventricle of an aged, female Siamese cat with both clinical and histopathological evidence suggestive of a thiamine deficiency encephalopathy. Both a thiamine related biochemical lesion and neurogenic
Using male rats fed a thiamine deficient diet from the age of 35-days, an investigation was made of the effects on testicular tissue after 30 days of thiamine deficiency. It was found that: 1) In the thiamine deficient group, the seminiferous tubuli of rats having erections had atrophied and there
Electron microscopic investigations on sciatic and plantar nerves of thiamine deficient and starved rats show a distally pronounced axonal degeneration. The changes are present in starved and thiamine deficient animals, but the deficient animals are more severely affected. The earliest alterations
