Does antidepressant therapy improve cognition in elderly depressed patients?

Objectives: To analyze the effects of antidepressants on cognitive functioning in elderly depression.

Methods: Data were pooled for elderly participants with major depression from two double-blind 12-week studies (n = 444) comparing sertraline to fluoxetine and to nortriptyline. A cognitive battery was performed pre-treatment and post-treatment that included the Shopping List Task (SLT), which quantifies short-term and long-term memory storage and retrieval, and the Digit Symbol Substitution Test (DSST), which measures visual tracking, motor performance, and coding.
