Quote:
The classification of depression (what types of depression exist) is a controversial topic that has caused much debate between psychiatrists. If there are different types of depression then they may have different causes and outcomes, and respond to different treatments.
Dispute arises because diagnoses are simply based on the presence of certain, arbitrarily defined, symptoms.

Nothing all that new. The debate continues.
