I am interested in the science of depression, mostly in its causes. I know that a lot is still being researched, but so far, I have heard of the following theories:
- chemical imbalance in the brain (caused by what?)
- vitamin deficiencies
- food intolerances
- copper toxivity syndrome (is that really a thing?)
- life changes (negative and positive)
I would especially like to know how someone suddenly gets really depressed without any known changes or causes, and how positive life changes can cause depression. Isn't that like, I don't know, saying quitting smoking causes cancer?
