Purpose:

This study will determine the effectiveness of combining escitalopram, venlafaxine, or duloxetine with donepezil, a medication used in Alzheimer's disease, in improving memory, concentration, attention, and problem solving abilities, and reducing the risk of depressive relapse in older individuals with depression.


Study summary:

The purpose of this research study is to learn if combining an antidepressant medication (escitalopram, venlafaxine, or duloxetine) with a medication used in Alzheimer's Disease (donepezil), in elderly patients age 65 and older with major depression, will help to 1) improve and/or maintain memory, concentration, attention, and problem solving abilities such as ability to balance a checkbook, pay bills, use the telephone, and 2) reduce the risk of depressive symptoms from returning. Study participation will last up to two years. We aim to investigate pharmacologic strategies for improving and stabilizing cognitive functioning in late-life depression and minimizing progression of cognitive and associated functional impairment. Cognitive impairment in late-life depression has not been adequately addressed in previous intervention research, is a core feature of the illness, contributes markedly to disability and impaired quality of life, and is an overlooked but potentially critical target of intervention. Data from the MTLD II study suggest that treating depression does not normalize cognitive functions and may not prevent their progression. We will test a pharmacologic strategy involving the cholinesterase inhibitor donepezil, in combination with maintenance antidepressant pharmacotherapy (escitalopram, venlafaxine, or duloxetine), to improve and to maintain cognitive functioning and functional competence in elderly patients with major depression. We hypothesize that maintenance antidepressant pharmacotherapy combined with donepezil will be superior to maintenance antidepressant pharmacotherapy combined with placebo/clinical management in (1) improving cognitive performance; and (2) slowing progression of cognitive impairment and decline in functional competence. We plan to recruit 200 patients aged 65 and above in current episodes of major depression. Those who respond to antidepressant pharmacotherapy with citalopram, venlafaxine, or duloxetine will then be randomly assigned on a double-blind basis to one of two 24-month treatments: 1)antidepressant pharmacotherapy plus donepezil/clinical management; or 2)antidepressant pharmacotherapy plus placebo/clinical management.
