The hidden aspects of depression

The NY Times blog, the New Old Age, has a post about depression amongst the elderly.  The basic premise is that we still do not have a good way of diagnosing depression on sight alone.  We assume depression must be accompanied by over sadness when in fact depression can manifest itself by means of a lack of desire.  What is scary is that those who are suffering from depression don’t recognize that they are depressed, instead many just assume they are in a rut.
