Background: Although significant evidence suggests that diminished monoamine function is associated with clinical depression, catecholamine or indoleamine depletion alone has not been associated with significant mood changes in unmedicated depressed subjects or never-depressed control subjects. This study assesses the integrated role of these monoamine systems in depressed patients.
Methods: Unmedicated depressed subjects underwent a 2-week, double-blind, random-ordered crossover study consisting of the following active and control conditions respectively: indoleamine (via tryptophan depletion) plus catecholamine (via alpha-methyl-paratyrosine administration) depletion and, separately, indoleamine plus sham (via diphenhydramine administration) catecholamine depletion.
