2. This statement is a misunderstanding of a paper;

4. At present, many theories of depression have been supported by research, but none of them can fully explain the causes of depression.

The most important person in my life is a patient with severe depression.

A few years ago, every time she suffered from depression, she always seemed to lose interest in everything in the world, which greatly affected her normal life. Seeing her day-to-day depression and sometimes even suicidal thoughts, I often feel at a loss.

And even if I can do something to dispel her temporary depression, I can't dispel the sense of powerlessness that "the black hand behind the scenes is still at large"

After all, what is the chief culprit leading to depression?

A recent news circulating on the Internet seems to give countless people who share my feelings an answer: "Depression is probably a highly contagious parasitic disease". At first glance, I am both happy and worried: I am glad that once the "behind the scenes" is confirmed, drugs for this pathogen will come out soon, which will help my beloved stay away from depression; Worryingly, it is far from fashionable. If depression is "highly contagious", aren't the caregivers of patients with depression also high-risk groups? Others who believe in it are also interested. Aren't they afraid of people with depression?
