               [摘   要] 抑郁症是一种发病率高、隐匿性强且复发率高的神经精神疾病,严重威胁人类身心健康。海马作为调节情绪和认
                知功能的关键脑区,其齿状回区在成年期持续存在神经发生。近年来,大量证据表明成体海马神经发生过程与抑郁症的发生
                发展密切相关。然而,成体海马神经发生异常与抑郁症病理的因果关系尚没有得到系统的总结和论证。文章通过系统梳理文
                献得出支持抑郁症“成体海马神经发生假说”4个方面的逻辑关系:减少成体海马神经发生诱发抑郁表型及相关病理;抑郁模

                系统地进行抑郁症“成体海马神经发生假说”的因果逻辑论证和证据总结,将为抑郁症的病理机制和抗抑郁药物研究提供新的
                视角。

               [Abstract] Depression,as a neuropsychiatric disorder with high prevalence,strong concealment and high relapse rate,is a serious
                threat to human physical and mental health. The hippocampus,a key brain region for regulating emotional and cognitive functions,has
                been found to have persistent neurogenesis in its dentate gyrus during adulthood. In recent years,a large amount of evidence suggests
                that adult hippocampal neurogenesis processes are closely related to the pathophysiology of depression. However,the causal
                association between adult hippocampal neurogenesis and the pathology of depression has not been systematically summarized. In this
                review,we summarized four aspects of evidence supporting the‘adult hippocampal neurogenesis hypothesis’of depression:the
                reduction of adult hippocampal neurogenesis induces depressive phenotypes and related pathologies;depression models reduce adult
                hippocampal neurogenesis;the increased adult hippocampal neurogenesis exerts antidepressant effect;and current antidepressants
                treatment increases adult hippocampal neurogenesis. This review is the first to comprehensively and systematically summarize the
                causal role of adult hippocampal neurogenesis in depression,providing new perspectives on the mechanisms of depression and
                antidepressants.
