FAAH inhibition is considered a powerful approach to enhance the endocannabinoid signalling, and therefore it has been largely studied as a potential target for the treatment of neurological disorders such as anxiety or depression, or of inflammatory processes.
These data provided preliminary evidence that genetically reduced FAAH activity and repetitive stress in the childhood are associated with increased vulnerability for anxiety and depression in later life.
The evidence outlined above supports the hypothesis that the EC system plays an important role in anxiety and mood disorders and suggests that modulation of FAAH activity might be a pharmacological target for novel anxiolytic and antidepressant therapies.
