Depression (抑郁症) is a serious problem today.Depression causes workers to be unproductive,causing companies and countries to lose billions of dollars.One expert says that depression is like cancer because it is “widespread,costly and deadly”.Depression hits one person in five around the world.

Although people have believed depression to be a problem among the rich and educated,studies show that depression is a problem among everyone.Over any six­month period,between five to seven percent of the world’s population will be suffering from a serious depression.Suicide rates among people suffering from the disease in its extreme,or clinical form were 80 percent higher than in the population at large,and sufferers were four times more likely to have heart attacks.People who suffer from depression often have problems sleeping,getting up on time,and doing work productively.

Depression,which researchers agree has its origin in the genes,brings loss of confidence and ability to concentrate—making it impossible for employees and managers to work efficiently.

Depression is made more serious in China by Chinese’s inability to face it.Many people believe that depressed people are either weak or lazy.Besides,there is no good treatment,with few specialists available.“Most patients in China just don’t get help,”a Chinese doctor says.“In my hospital,I have to see 30 or 40 patients in a morning,just have time to say ‘Hello,how do you feel?’”

In Western countries,people are not afraid to admit that they have depression,but most do not tell it to their boss,because they fear that they will be stricken_off_the_rolls.“In my experience,aging bosses are the most willing to admit they have it.Because they feel the most secure about themselves,” an American doctor says.

Hopefully,in the near future,people around the world will be able to admit that they have depression so that they can get the right treatment.
