What are the best new treatments for mood disorders?

Standbys: I am not sure that the best treatments are all that 'new.' meds are not my area, though some now work with fewer side effects. In therapy, again i say the *relationship* heals, with brief psychodynamic, cbt, interpersonal, and other 'techniques' helpful. 'trendy' therapies tend to be better or worse repackagings of those elements. That's actually good news-find a solid, traditional therapist.
