她那么爱笑，为什么还会得抑郁症？警惕“微笑型抑郁”

大部分的人对抑郁症存在刻板印象，觉得患者都是闷闷不乐、对生活毫无兴趣的人。然而，并不是每个人都以同样的方式经历抑郁症。

部分抑郁症患者患有“阳光型抑郁症”（smiling depression），也称“微笑抑郁症”。简单地说，这是一种隐藏的抑郁症。其定义为在别人面前表现得很开心，表面在笑，内心却患有抑郁症状。

Simply put, "smiling depression" is depression disguised. The definition of smiling depression is: appearing happy to others, literally smiling, while internally suffering from depressive symptoms. Smiling depression often goes undetected. Those suffering from it often discount their own feelings and brush them aside. They might not even be aware of their depression or want to acknowledge their symptoms due to a fear of being considered "weak".

微笑抑郁症通常不会被发现，患者往往不重视自己的感受，将其放在一边。由于害怕被认为“软弱”，他们甚至可能自己都没有意识到患病，或不想承认。

对抑郁症的一种常见的误解是：抑郁症只是忧郁，不是真的疾病。

实际上，抑郁症是一种全球常见病。根据世卫组织（WHO）今年3月发布的数据，据估计，3.8%的全球人口受此影响，其中5.0%的成年人和5.7%的60岁以上成年人患有抑郁症。世界上大约有2.8亿人患有抑郁症。

Depression is a common illness worldwide, with an estimated 3.8 percent of the population affected, including 5.0 percent among adults and 5.7 percent among adults older than 60 years. Approximately 280 million people in the world have depression.

抑郁症患者的脑部扫描能显示出疾病的生物学证据。在神经间传输信号的关键大脑化学元素也表现出失衡的状态。患有临床抑郁的人并不是懒惰或自怨自艾。他们也无法用“意志”赶走抑郁。和其他疾病一样，抑郁症通过正确的治疗，可以得到缓解。

Depression is a serious medical condition. Biological evidence of the illness can be seen in brain scans. Key brain chemicals that carry signals between nerves also appear to be out of balance in depressed people. People who have clinical depression are not lazy or simply feeling sorry for themselves. Nor can they "will" depression to go away. Like other illnesses, it usually improves with appropriate treatment.
