If you’re over 60, light alcohol associated with better memory

Researchers from the University of Texas Medical Branch at Galveston, University of Kentucky, and University of Maryland found that for people 60 and older who do not have dementia, light alcohol consumption during late life is associated with higher episodic memory — the ability to recall memories of events.

The researchers found that light and moderate alcohol consumption in older people is associated with higher episodic memory and is linked with larger hippocampal brain volume. Amount of alcohol consumption had no impact on executive function or overall mental ability.

Findings from animal studies suggest that moderate alcohol consumption may contribute to preserved hippocampal volume by promoting generation of new nerve cells in the hippocampus. In addition, exposing the brain to moderate amounts of alcohol may increase the release of brain chemicals involved with cognitive, or information processing, functions.

“There were no significant differences in cognitive functioning and regional brain volumes during late life according to reported midlife alcohol consumption status,” said lead author Brian Downer, UTMB Sealy Center on Aging postdoctoral fellow. “This may be due to the fact that adults who are able to continue consuming alcohol into old age are healthier, and therefore have higher cognition and larger regional brain volumes, than people who had to decrease their alcohol consumption due to unfavorable health outcomes.”

Although the potential benefits of light to moderate alcohol consumption to cognitive learning and memory later in life have been consistently reported, extended periods of abusing alcohol, often defined as having five or more alcoholic beverages during a single drinking occasion is known to be harmful to the brain.
