Binge Drinking Tied to Alzheimer’s Risk

Middle-Age Drinking Habits Tied to Alzheimer's RiskA new long-term study adds support to the premise that mild alcohol consumption in middle age appears to protect against dementia.

In the study, published in the Journal of Alzheimer’s Disease, subjects were followed for more than two decades.

Researchers from the University of Turku, University of Helsinki and National Institute for Health and Welfare in Finland monitored subjects from the Finnish Twin Cohort.

They believe the investigation gives solid support to the notion that midlife alcohol consumption is related to the risk of dementia assessed some 20 years later.

The study indicates that both abstainers and subjects consuming large amounts of alcohol have a greater risk for cognitive impairment than light drinkers.

“Our finding is significant as the changes typical of Alzheimer’s disease – the most common dementia syndrome – are thought to start appearing two to three decades before clinical manifestation and therefore identification of early risk factors is imperative,” states Jyri Virta, researcher at University of Turku, Finland.

In addition to total alcohol consumption, the authors were able to assess the effects of different drinking patterns.

The study suggests that drinking large amounts of alcohol (defined as a bottle of wine or the equivalent) at a single occasion at least monthly is an independent risk factor for cognitive impairment.

Such binge drinking doubles the risk of cognitive impairment even when total alcohol consumption was statistically controlled for.

Similarly, passing out because of heavy drinking on one occasion was also found to increase the development of subsequent cognitive impairment.

Thus, it is not only the amount of alcohol, but also the pattern by which alcohol is consumed that affects the risk of cognitive impairment.

The published study is among the first to report these effects.
