title: Clinical predictors of response to antidepressants in elderly patients.
abstract: A group of 42 patients, ages 55 and above, suffering from major depression were examined in an attempt to isolate clinical variables that would predict response to antidepressants. These patients were part of a placebo-controlled, double-blind study and were given either nortriptyline or phenelzine for 5-7 weeks. There was no significant difference in response rates between patients subclassified as endogenous or nonendogenous by either RDC or Newcastle criteria. No difference in response rates was found between the DSM-III melancholic and nonmelancholic subtypes. Neither drug preferentially treated a subtype. None of the 21 variables representing symptoms, demographic traits, or characteristics of the depressive illness were found to be significant predictors of antidepressant response.
