Heavy drinking leads major dementia, especially with more risk to the middle age people, according to the latest French research.

Risk of encountering dementia may be significantly up because of excessive drinking more likely in older people as compared to those, who are light drinkers or non-drinkers, informs a recently released review by the journal Lancet.

Dementia is a range of diseases related to the brain that causes a gradual or long-term memory disorders, impaired reasoning, personality changes, emotional problems, decrease in motivation and problems with language.

Study’s leading author and chief executive officer Dr. Michael Schwarzinger from the Translational Health Economics Network Translational Health Economics Network, who also work for the INSERM–Universite Paris Diderot in France, stated that, “Chronic heavy drinking was the most important modifiable risk factor for dementia onset in both genders and remained so after controlling for all known risk factors for dementia onset.”

The World Health Organization has reported that nearly 3.3 million people die every year because of misusing the alcohol that accounts for around 6 per cent of all the recorded deaths. however, the earlier researches indicates that alcohol causes cognitive impairments such as risk of dementia, while other studies suggest that moderate or light alcohol lead to the healthier brain, according to the research in the Lancet Public Health.

Schwarzinger added that, “Surprisingly, heavy drinkers who got sober didn’t have a lower dementia risk than their peers who remained problem drinkers. This finding supports that chronic heavy drinking leads to irreversible brain damage.”
