    Background: Effective treatments to alleviate depression in Alzheimer's disease (AD) have been scarce. Objective: To investigate the efficacy and tolerability of escitalopram in the treatment of depression in AD. Methods: In this 12-week randomized, double-blind, placebo-controlled trial with open-label, 12-week extension, AD subjects over 50 years of age, with depression defined by Olin's provisional diagnostic criteria, were enrolled. The Cornell Scale for Depression in Dementia (CSDD), and other measures of depression and cognition were repeated. Results: 91 subjects were screened, and 84 were randomized into either the study group or placebo group (n = 42 for both groups). Twenty-four subjects (29) were unable to finish the study, yielding a per protocol population of 60 subjects (study group: n = 27; placebo group: n = 33). At week 12, differences in measures of depression and cognition between the two groups were not statistically significant. However, exploratory analysis suggested that further research on a subset of subjects with 'definite major depression' (baseline CSDD score ≥18) is needed. The number of treatment-related adverse-events (AE) did not differ between groups (p = 0.83) and no serious treatment-related AE were observed. Conclusion: The use of escitalopram was well tolerated in depressive dementia patients. Future studies focusing on subjects with more severe levels of depression, and with more statistical power, will be needed.
