Frances' complaint in a nutshell is that the DSM-5 creates fad diagnoses and changes criteria of older diagnoses to medicalize a whole range of normal behavior and miseries. The link lists these problem diagnoses and a number of the following points, in an article published all over town last December.
These issues have been discussed widely, in public and private circles. I am not qualified to address each point, though I did give a series over to one of them, the bereavement exclusion. The best of the batch, if I do say so myself, is Grief/Depression III - Telling the Difference, which got quoted in correspondence among the big boys.
