Continuation treatment of delusional depression in older adults.

Overview
abstract
Delusional depression responds poorly to acute antidepressant monotherapy but appears to respond to intensive combination pharmacotherapy, however with poor short-term outcomes after initial improvement, particularly in later life. The authors compared the efficacy and safety of continuation combination therapy to monotherapy among older patients after remission from a delusional depression. Twenty-nine older adults with SCID-diagnosed major depression with delusions received continuation treatment with nortriptyline-plus-perphenazine or nortriptyline-plus-placebo under randomized double-blind conditions after achieving remission after ECT. Of the 28 subjects included in efficacy analyses, 25% suffered relapses. The relapse frequency was nonsignificantly greater in combination therapy than in monotherapy subjects. However, combination subjects had significantly more extrapyramidal symptoms, an increased incidence of tardive dyskinesia, and a greater number of falls. Continuation treatment with a conventional antipsychotic does not decrease relapse rates but is associated with significant untoward adverse events in older persons after recovery from a delusional depression.
