Alcohol sensitivity in healthy adults aged 65–80 who drink

Official title: Individual Differences in Alcohol Sensitivity

Run by University of Florida · NCT07636447 · Data updated 2026-11-12

This study tests how older adults who regularly drink respond to a moderate amount of alcohol, to see how their cognition and brain activity may change.

Is this trial a fit for you?

Likely a good fit

Healthy adults aged 65–80 who regularly consume alcohol and have at least 12 years of education, without significant substance misuse or major neuropsychiatric or metabolic disorders.

Probably not a fit

Individuals with current smoking, certain chronic conditions (eg, uncontrolled diabetes, epilepsy, neurodegenerative or major psychiatric disorders) may not experience benefit from participation.

What this trial studies

This is a proof-of-concept study enrolling healthy adults aged 65 to 80 who regularly drink. Participants attend two lab sessions in which they complete questionnaires and cognitive and brain activity measures, and receive beverages that may or may not contain a moderate dose of alcohol. If alcohol is given, the amount will approximate what is consumed in 1–2 standard drinks. The study aims to describe variability in alcohol response among older adults and explore links between alcohol sensitivity and cognitive test results. About 75 individuals are planned to participate, conducted at the University of Florida with collaboration from NIAAA.

Why it matters

Potential benefit: If successful, findings could improve understanding of how age-related factors influence alcohol response and cognition in older drinkers.

How similar studies have gone: Previous work has explored alcohol effects on cognition in various groups, but this specific older-drinker, two-session, randomized beverage design is relatively novel.
