Abstract

Depression is one of the most prevalent and costly brain diseases. Available antidepressant drugs are safe and effective, but less than half of all patients attain complete remission with single antidepressant and others exhibit partial, refractory or intolerant responses to treatment. Therefore, these findings emphasize the need to discover new antidepressants. The neurogenic hypothesis postulates that a reduced production of new neurons in the adult hippocampus is involved in pathogenesis of depression and an enhancement of hippocampal neurogenesis is one of mechanisms for the successful antidepressant treatment. This article examines this hypothesis with experimental and clinical data.
