Bad for the Brain, Warn Researchers By Emily Woodruff |

February 21st, 2018In recent years, researchers have found

evidence that a daily glass of wine may bolster brain health,

but scientists still debate whether alcohol, in any amount, should

be recommended to lower dementia risk. Many studies point

to the damaging effects it has on the brain and new evidence,

published this week, shows that drinking too much alcohol

regularly can increase risk for all types of dementia, especially

early-onset Alzheimers.A recent study published in the

journal Lancet Public Health showed that data from over a

million adults points to excessive alcoholism as a dangerous

risk factor for dementia. Researchers looked at data from the

French National Hospital Discharge database and found that

alcohol-use disorders were present in 16.5 percent of men with

dementia and 4 percent of women with dementia thats twice as

much as in those without dementia in the case of both men and women.

The study paid special attention to the link between early-onset

dementia, classified as anyone with a diagnosis under the age of 65.

Of the 57,000 cases of early-onset dementia, researchers found

that 57 percent were related to chronic drinking.But how much

alcohol is too much alcohol? The World Health Organization

defines chronic drinking as more than 60 grams of pure alcohol

per day for men four to five drinks) and more than 40 grams of

pure alcohol per day for women three drinks).We've known for a

while that heavy drinking can increase your risk of developing dementia.

This study suggests that alcohol abuse disorders may be responsible

for more cases of early-onset dementia than previously thought,

said Doug Brown, Chief Policy and Research Officer at Alzheimers Society.However, Brown points out that this study was limited to

France, and other countries may have different drinking habits that

could affect risk of early-onset differently.This study in no way

suggests that moderate alcohol intake could cause early-onset dementia.

The study doesn't change the advice to stick to no more than

14 units [one unit is how much pure alcohol an adult can process

in an hour] of alcohol a week, said Brown. Researchers who led the

study suggested that this information should lead to screenings for

alcohol use and interventions and treatment for alcohol disorders in

order to curb dementia.The findings indicate that heavy drinking and

alcohol-use disorders are the most important risk factors for dementia,

and especially important for those types of dementia which start before age 65,

and which lead to premature deaths, said study co-author and Director of

the Centre for Addiction and Mental Health CAMH) Institute

Dr. Alcohol-induced brain damage and dementia are preventable,

and known-effective preventive and policy measures can make a

dent into premature dementia deaths.And not only does heavy alcohol

use increase dementia risk; it also increases risk for a number of other

factors associated with dementia, like tobacco smoking, high blood pressure, diabetes, lower education, depression and hearing loss.

For many of those people, dementia is the cause of death.

As a geriatric psychiatrist, I frequently see the effects of alcohol-use

disorder on dementia, when unfortunately alcohol treatment

interventions may be too late to improve cognition, said CAMH

Vice President of Research Dr. Screening for and reduction of

problem drinking, and treatment for alcohol-use disorders need to

start much earlier in primary care.This study was published in the

journal Lancet Public Health.
