Background: Alcohol hangover is a common occurrence among individuals who have
experienced an episode of heavy alcohol consumption the previous night. Until now defined as the
general feeling of misery that develops once the Blood Alcohol Concentration approaches zero. Despite
its prevalence and several related adverse consequences, insufficient research has been conducted
with regards to this matter and further understanding of the pathology of alcohol hangover is
necessary. During the 9th Alcohol Hangover Research Group meeting, held on April 29th 2017,
Utrecht, The Netherlands, numerous aspects of alcohol hangover were presented and many advances
with regards to determinants, biological and cognitive consequences and potential treatment
have been presented.
Conclusion: Precisely, a definition of alcohol hangover has been established and wider understandings
of biological and cognitive effects, alcohol metabolism, immune functioning and potential
treatment of alcohol hangover were presented and discussed. Further research and development are
necessary to attain a wider understanding of the pathology of alcohol hangover.
