Moderate alcohol consumption could make memories more painful, claim scientists.
New research at UCL (University College London) claimed that people who have drunk a moderate amount of alcohol before a traumatic event report more flashbacks than those who have had no alcohol.The results may give new insight into why some individuals develop post traumatic stress disorder (PTSD) after a traumatic event and others do not.
The study has been published in the journal Biological Psychiatry.
In the research, boffins also found that those who drank a large amount of alcohol before a traumatic event did not report an increase in the number of flashbacks.
"Many people who experience a personally traumatic event such as rape or a road traffic accident have consumed alcohol beforehand. For the first time, this research gives us an idea of how being under the influence of alcohol might contribute to our wellbeing later on," said James Bisby, from UCL's Department of Clinical, Educational and Health Psychology, who led the research.
Scientists believe that the findings can be attributed to how alcohol affects two types of memory: one that is egocentric, providing a visual 'snapshot' of an event, and another that stores a mental representation of the context of the event, which is independent of the person's viewpoint.

During the study, nearly 50 participants consumed either alcohol or a placebo drink and then performed a virtual reality task designed to examine how an experienced event is stored within memory. They were then shown a video of serious road traffic accidents and recorded the number of times they spontaneously re-experienced any of the footage, i.e. had a flashback, over the following 7 days.
