This is a well referenced article up on +BuzzFeed
that I think we should all spend the time reading and discussing seriously. One of the main questions discussed is the vague generalization Depression
may provide and a proposal to subdivide it into three separate categories to, among other uses, make treatment much more effective.
I think this might be a good start. In looking at how the *+Mayo Clinic
categorizes depression, it seems like the simplified term depression
hurts us as a society by placing a barrier to understanding. They list eight forms of depression, each of which could easily be their own disease, investigated and treated separately. Imagine now if we included mania as well, breaking that down. I would think our ability to identify and treat people's mental illnesses would improve tenfold.
