NCT05899660

Brief Summary

The goal of this clinical trial is to investigate the biological pathways underlying the beneficial effect of omega-3 polyunsaturated fatty acids (n-3 PUFA) on mental health in patients with alcohol use disorder. The main questions this study aims to answer are:

  • Can n-3 PUFA improve mood disorders (depression, anxiety), craving for alcohol, cognitive impairments and sociability disorders ?
  • Are the beneficial effects of n-3 PUFAs due to a modification of the gut microbiota and/or the inflammatory status? Participants will :
  • take a supplementation of omega-3 or placebo during 3 months
  • do a brain MRI
  • be interviewed for a dietary anamnesis
  • provide blood, stool and saliva samples
  • perform psychological tests and neuropsychological tasks Researchers will compare active comparator (omega-3) with placebo comparator (olive oil) to see if omega-3 can have a beneficial effect on AUD patients.
