Heavy drinking harms the aging brain

Heavy drinking harms the aging brain

We already know that heavy drinking can have harmful effects on the body, so it comes as no surprise that it can negatively impact an aging brain, too. The study found heavy drinking can take a toll on many brain functions, including memory, attention, and learning.

The researchers from the University of Florida asked 31 men and 35 women to complete a series of brain tests.

The participants were divided into groups based on their alcohol intake: non-drinkers, moderate drinkers, and heavy drinkers.

Nearly 53 percent of the participants had a lifetime history of some point of alcohol dependency and 21 percent were considered heavy drinkers. The researchers also monitored total brain functions like attention, learning, memory, motor function, and more.

The study found that older heavy drinkers had lower scores on cognitive function. A lifelong history of alcohol dependency was also associated with worse learning, motor function, and memory. These participants also had reductions in their attention or executive function (such as reasoning and working memory), regardless of age.

Dr. Marc Gordon, chief of neurology at Zucker Hillside Hospital, said, “It is not surprising that lifetime alcohol dependence would have long-term adverse effects on cognition [thinking], nor is it surprising that heavy alcohol use in older adults would also be associated with worse cognition.”

Dr. Gisele Wolf-Klein, a geriatrics doctor at Northwell Health, added, “Medication regimens can be negatively affected by the use of alcohol. Use of alcohol is better avoided altogether in older adults — or at least reported and discussed openly with their primary care doctors.”
