5. Study Description
Brief Summary
Depression and bipolar disorder (mania and depression) may be related to problems with nerve cells not being regenerated as fast as normal and are accompanied by cognitive difficulties including memory, attention and planning problems. There is thus a need for better, more efficient treatments with effects on cognitive function. Erythropoietin (Epo) is involved in brain repair and may be a candidate for future treatment strategies. The investigators have demonstrated that a single dose of Epo improves mood and reduces the processing of negative emotional information in healthy volunteers similar to effects seen with antidepressants. With the current study the investigators aim to build upon this discovery by investigating whether repeated Epo administration has antidepressant effects and is able to reverse cognitive difficulties in patients with depression or bipolar disorder. It is hypothesized that Epo will improve mood in treatment-resistant depression and improve cognitive function in this group and in patients with bipolar disorder in remission. If the study reveals beneficial effects of Epo, this would highlight Epo as a candidate compound for future treatment of depression and bipolar disorder, with the potential to directly promote brain repair mechanisms.
