Nationwide study conducted in France suggests that the burden of dementia caused by alcohol is much larger than previously estimated and use of alcohol directly contribute to lifelong brain damage.Of the 57,353 cases of early-onset dementia, 56.5% cases were related to alcohol use.
Alcohol use was also associated with other independent risk factors for onset of dementia.These risk factors are
- Thiamine deficiency,
- Epilepsy, head injury, and hepatic encephalopathy in patients with cirrhotic liver disease,
- Vascular risk factors such as high blood pressure, haemorrhagic stroke, atrial fibrillation, and heart failure.
- Heavy drinking is associated with tobacco smoking, depression, and low educational attainment
- (Heavy drinking as defined by WHO is drinking at least 60 g of pure alcohol per day for men and at least 40 g for women)
These findings suggest that alcohol use contribute to the risk of dementia in multiple ways.
Study suggested following cost effective measures for prevention alcohol induced dementia:
- Primary care: Early detection, behaviour therapy, and treatment for alcohol dependence
- Government's policy measures such as restricted supply of alcohol, increase in taxation, and ban on advertising.
