Abstract:
This study aimed to determine whether botulinum toxin type A injected into the muscles of the upper third of the face has antidepressant effects in patients diagnosed with depression. Studies seeking a relationship between botulinum toxin type A and its antidepressant effects were considered in this review. All studies concluded that the facial expression muscles present positive feedback to the brain and enhance mood states. Botulinum toxin when applied to the corrugator and procerus muscles has an antidepressant effect.
