9. The method of claim 8, wherein the monoamine metabolite is 5-hydroxyinoleacetic acid (5-HIAA).

10. The method of claim 1, wherein the subject has a polymorphism in the tryptophan hydroxylase gene in intron 7.

11. The method of claim 1, wherein the subject has had a major depressive episode.

17. The method of claim 1, wherein the subject is administered a mood stabilizing, antidepressant, antipsychotic, or anxiolytic medication at least one week, prior to administration of the mecamylamine or TC-5214.

18. The method of claim 1, wherein both mecamylamine and TC-5214 are administered to the subject.

19. The method of claim 1, wherein the mecamylamine is administered to the subject.

20. The method of claim 1, wherein the subject has not suffered a major depressive episode.

21. The method of claim 1, wherein the subject is not suffering from major depressive disorder.

22. The method of claim 1, wherein the subject is not suffering from bipolar disorder.

23. The method of claim 1, wherein the suicidality is thereby eliminated.
