Right on that page there's an interesting talkback which made me think about depression in a new way, other than "just" faulty neurons or sad experiences in life.
I wonder how many different sorts of depression are there...

My own experience researching depression -- or rather researching people who research depression -- suggests that, like autism, depression will increasingly get broken down into diagnostic and mechanistic subtypes as we learn more about it. Depression as currently described is really a set of symptoms rather than defined mechanisms; as we spot different mechanisms at work, the diagnoses, the treatments, and perhaps the very concept of depression will change.
