Biological mechanisms and clinical efficacy of sulforaphane for mental disorders

Current clinical management of major mental disorders,such as autism spectrum disorder,depression and schizophrenia,is less than optimal.Recent scientific advances have indicated that deficits in oxidative and inflammation systems are lessthanoptimal.Recentscientific advances have indicated extensively involved in the pathogenesis of these disorders. These findings have led to expanded considerations for treatment.Sulforaphane(SFN)is a dietary phytochemical extracted from cruciferous vegetables.It is an effective activator of the transcription factor nuclear erythroid-2 like factor-2,which can upregulate multiple antioxidants and protect neurons against various oxidative damages.On the other hand,it can also significantly reduce inflammatory response to pathological states and decrease the damage caused by the immune response via the nuclear factor-kB pathway and other pathways.In this review,we introduce the biological mechanisms of SFN and the pilot evidence from its clinical trials of major mental disorders,hoping to promote an increase in psychiatric clinical studies of SFN.
