What are some interesting DSM-IV topics for a research paper?

[DudeThatsAwesome]

I'm a psychology student and I need to write a research paper on a DSM-IV diagnosis. In the paper, I need to include symptoms, associated features, etiology and treatment approaches. Any ideas/interesting topics will be greatly appreciated. Thanks!

I find Schizophrenics fascinating - of course the treatments(especially for severe ones )are not very effective.

Histrionic Personality Disorder is really interesting, as well as any Conversion Disorders.
