Prescription EPO... for depression...

Well this is interesting.... imagine a rider who is 'suffering' depression, perhaps because they are not winning? OK, too obvious. Perhaps they really are clinically depressed. In the near future they may well be prescribed EPO to lift their spirits... I'm feeling depressed just thinking about it!
From Physorg.com: A search for novel treatment strategies in coping with depression has revealed that erythropoietin, or Epo, a hormone naturally produced by the kidneys to stimulate the formation of red blood cells, affects cognitive and associated neural responses in humans, and could potentially be used in the treatment of depression. The study, published in Biological Psychiatry by Oxford University researchers based at the Department of Experimental Psychology and the Warneford Hospital, Oxford, found that Epo, known as a treatment for anaemia, modulates human brain activity associated with the processing of emotion.
