Description
Male subjects with unipolar Major Depressive Disorder (DSM-IV) with a minimum score of 22 on the 10-item Montgomery-Åsberg Depression Rating Scale (MADRS) who were medication-free for at least 6 weeks, were enrolled. Fifteen individually age-matched (+ 3 years) healthy male controls with no history of psychiatric illness were also enrolled. Subjects' ages ranged from 22- 55 y.o. (mean + S.D.= 41.4 + 8.75 y.o.). All subjects were required to pass a urine toxicology screen (assessing the presence of drugs of abuse) on the day of testing.
Exclusion Criteria:
Individuals with co-morbid panic disorder were excluded, since they may poorly tolerate typical starting doses of antidepressants , and individuals with co-morbid post-traumatic stress disorder were excluded, since they may have neuroendocrine regulatory responses different from those of depressed subjects without PTSD. Exclusion criteria for both groups included recent (within 6 months) alcohol or drug abuse as defined by DSM-IV criteria, concurrent psychotherapeutic interventions, poor medical health or abnormal clinical labs, active suicidality, and use of medications that could interfere with the study.
