In this study, Miskowiak and colleagues evaluated the effects of Epo on the neural and cognitive processing of emotional information in healthy volunteers using functional magnetic resonance imaging (fMRI). They found that Epo regulated the emotional responses of those volunteers that received it, similar to the effects of current antidepressants. Ms. Miskowiak explains that “this finding provides support to the idea that Epo affects neural function and may be a candidate agent for future treatment strategies for depression.” John H. Krystal, M.D., Editor of Biological Psychiatry and affiliated with both Yale University School of Medicine and the VA Connecticut Healthcare System, confirms its potential: “Epo appears to have neurotrophic effects in the brain in animals. The current data suggest that Epo may modulate human brain activity associated with the processing of emotion. Together, there may now be sufficient evidence to justify evaluating the antidepressant effects of Epo and related compounds in humans.”
