We investigated the antidepressant efficacy of l-deprenyl (selegiline), a selective monoamine oxidase B inhibitor (MAOI), in a six-week open trial of 17 patients with atypical depression. Such patients have previously been shown to benefit from nonselective MAOIs such as phenelzine sulfate. Ten patients (59%) responded to l-deprenyl, but nine required dosages above the 10 to 20 mg/day used in previous investigations. l-Deprenyl was superior to six weeks of placebo administered to diagnostically similar patients in a separate double-blind study. In contrast with previous findings with pheneizine, responders to l-deprenyl differed from nonresponders by having lower baseline anxiety ratings. Even at high dosages, there appeared to be fewer side effects with l-deprenyl than with nonselective MAOIs.
"Quitkin and colleagues (1984) tested the effects of selegiline (20 mg/day) on 17 atypical depressives without PD and found that improvement occurred in 60% of the patients. Mann et al (1989) conducted a double-blind placebo-controlled trial testing the effects of selegiline on patients suffering from primary depression. "
[Show abstract][Hide abstract] ABSTRACT: Depression is found in about 30%-40% of all patients with Parkinson's disease (PD), but only a small percentage (about 20%) receive treatment. As a consequence, many PD patients suffer with reduced health-related quality of life. To address quality of life in depressed PD patients, we reviewed the literature on the health correlates of depression in PD (eg, cognitive function), etiology of depression in PD, and treatment options (ie, antidepressants, electroconvulsive therapy, and psychotherapy). The current review is unique in its focus on psychosocial aspects, as well as neuropathological factors, of depression in PD. Overall, we conclude that neurochemical (eg, serotonin) and psychosocial factors (eg, coping style, self-esteem, and social support) contribute to the affective disturbances found in this neuropsychiatric population. Therefore, we recommend that a multidisciplinary (eg, pharmacotherapeutic, psychoeducational, and/or psychotherapeutic) approach to treatment be taken with depressed PD patients.

[Show abstract][Hide abstract] ABSTRACT: To examine the biochemical effects of 10-30 mg/day L-deprenyl, measurement of 24-hr urinary output of phenylethylamine (PEA), 3-methoxy 4-hydroxy phenylethyleneglycol (MHPG), and L-deprenyl's amphetamine metabolites were carried out before and during the treatment of atypical depressives. Platelet monoamine oxidase (MAO) activity was also assessed. With L-deprenyl 10-30 mg/day, the expected MAO B inhibition occurred, as indicated by significant increase in urinary PEA excretion and virtual disappearance of platelet MAO activity. Twenty-five to 33% of the daily dose of L-deprenyl was recovered as urinary methamphetamine or amphetamine. Excretion of MHPG was significantly decreased with L-deprenyl 10-20 mg/day. Overall, the results suggest that L-deprenyl's antidepressant effects are mediated by some mechanism other than, or in addition to, MAO B inhibition.
