> You can thumb through the DSM V and find countless seemingly well-defined "diseases" described using the language of science, yet for few is any underlying cause known and very often the "symptoms" are vague and useless for differential diagnosis.

To say nothing of the political nature of declaring something as being a disorder or not. Read about the decision to remove homosexuality back in the DSM-III and the decision to remove pedophilia in the DSM-V and realize how highly political these moves were (many professionals aren't even aware of that change in the DSM-V and unless you pay close attention, a reader could easily miss the differences between pedophilia in the DSM-IV-TR and pedophilic disorder in the DSM-V).
