Abstract

In a double-blind interindividual comparison 80 mg of an ACTH 4-9 analogue (Org 2766) or placebo was administered daily to 49 elderly depressed in- and out-patients for 4 weeks. 20 patients then changed to the opposite treatment in a cross-over study for a further 2 weeks. All patients were tested for memory on days 0 and 29 with a battery consisting of the 30 World-Pair Test, the 30 Figure-Test and the 30 Personal-Facta Test. Three scores were obtained from each test, immediate memory score (IMS), delayed memory score (DMS) and their difference, forgetting score (FS). Cross-over patients were tested for vigilance on days 0, 29 and 43 in an apparatus testing ability to rapidly detect and react to specific minor changes at random intervals. Org 2766 had no better effect than placebo on learning, consolidation, or retrieval of memorized material in elderly depressed patients. Statistically significant fewer target misses in the test of vigilance suggest a higher degree of sustained attention after treatment with Org 2766.
