Monoamine oxidase
RBD has also been reported following cerebrovascular accident and neurinoma (tumor), indicating that damage to the brain stem area may precipitate RBD. RBD is usually chronic. However, it may be acute and sudden in onset if associated with drug treatment or withdrawal (particularly with alcohol withdrawal). Monoamine oxidase inhibitors, tricyclic antidepressants, Selective serotonin reuptake inhibitors, and noradrenergic antagonists can induce or aggravate RBD symptoms and should be avoided in individuals with RBD.
