A second example: it has been known since antiquity that normal people who recently experienced a significant loss – especially of a loved one – can have the same symptoms (e.g., sadness, insomnia, fatigue, loss of interest in usual activities, lessened appetite) as those indicating major depressive disorder. Thus, the DSM currently eliminates the recently bereaved from depression diagnosis unless they have certain extreme symptoms suggesting more than intense grief.
再举一个例子：自古以来人人都知道如果一个正常人遭受了巨大的打击——例如失去爱人——会产生和重度忧郁症类似的症状，比如伤心、失眠、疲惫，对周围事物失去兴趣和食欲不振。因此，目前版本的手册将丧失亲人者排除在忧郁症之外，除非这些人确实有比极度悲伤更加极端的表面症状。
