It would seem there are various contributing causes of depression symptoms which would determine the relative severity (degree of dibilitation) of the condition. The most common, general cause would seem to be when an habitual pattern of mind has been established that forms the basis of the recognition of self. Depending on this pattern, the body itself may be guided in its expression. This expression, in turn, feeds back to the mind (emotionally and physically) which may help reinforce the pattern.
