With the interchangeable variants (excluding hearing voices, losing time and severe phobias) aren't all disorders just varying degrees of the same condition and what separates one from the other is its trigger - i.e. the environment/relationship in which it manifests? Look at the basis of virtually all disorders depression and anxiety are guaranteed to be listed and at the basis of all syndromes it's inertia and cognitive inhibition.
There is currently a rapprochement between neurology and psychiatry - so much so that some people have suggested the possibility of an eventual merger. The argument is that psychiatry developed on the foundation of a (now largely abandoned)
philosophy (Freudian psychoanalysis), while neurology developed based on hard scientific research. However, given that psychiatry is increasingly moving toward neuropsychiatry, the reasons for two distinct disciplines seem, to some people, less desirable.
Eventually, the DSM may be entirely restructured according to a combination of neurological research and responses to treatment over the life course.
