Consequences of alcohol consumption in humans: Hangover and other residual alcohol
effects: Predictors and consequences
Venue: Cap 15 conference center, Paris, France
The symposium will focus on the residual effects of an episode of drinking intoxication,
with emphasis on hangover and residual behavioral effects. Recent research has found
detrimental neurocognitive effects after alcohol has left the body the morning after
drinking to intoxication, effects that could affect safety-sensitive performance.
Although a number of studies find that 25-20% of drinkers do not report any hangover
the morning after heavy drinking, neurocognitive deficits occurred regardless of
sensitivity to hangover. The current symposium follows up that previous research
by investigating several determinants and consequences of heavy drinking. The first
study investigates whether hangover sensitivity in college adds to variance due to
drinking practices in predicting transitions to post-college drinking quantity/frequency.
The second study investigates hypothesized genetic predictors of hangover sensitivity.
The third study investigates functional changes in the brain using fMRI the morning
after drinking to alcohol intoxication compared to placebo. The fourth study examines
the relationship between hangover intensity and residual alcohol effects on attention/reaction
time. The discussant brings in the European perspective on the studies on residual
effects of an episode of heavy drinking. Schedule
