Frailty, "a syndrome of decreased resiliency and reserves", is defined by five characteristics: 1)"shrinking" (definition: unintentional weight loss of > 10 lbs in prior year, or > 5% loss of body weight in prior year at follow-up), 2) weakness (definition: grip strength in lowest 20% at baseline, adjusted for gender and BMI), 3) poor endurance/energy (definition: self-report of exhaustion on 2 items on the CES-D), 4) slowness (definition: slowest 20% on timed 4 meter or 15 foot walk, adjusted for gender and standing height), and 5) low physical activity (definition: weighted score of kilocalories expended per week as calculated from the Minnesota Leisure Time Activity questionnaire). Frailty is associated with poor prognosis including hospitalization, falls, worsening disability and mobility, and death.
Data from the Cardiovascular Health Study document the rate of comorbid depressive symptoms in frail older adults (16.2% of older adults with at least 1 frailty characteristic had a CES-D > 10, including 31% of older adults with 3 or more frailty characteristics, compared to 2.6% of nonfrail older adults) despite study exclusion of individuals who were taking an antidepressant (this is in part why we chose to include patients with a CES-D of > 10, rather than requiring a diagnosis of a depressive disorder such as major depression or dysthymia for this study). The relationship between frailty and depression however goes beyond this association; the five defining characteristics of frailty (exhaustion, decreased energy, weight loss, decreased grip strength, and slow/unsteady gait) overlap significantly with symptoms of geriatric depression (decreased energy and motivation, psychomotor slowing, weight loss, decreased participation in leisure activities).
The proposed study is innovative in that it is focuses on a group of older adults who have been unrepresented (via exclusion criteria) in previous clinical studies (frail older adults with comorbid depressive symptoms), and it treats the comorbid depressive symptoms and targets characteristics of the frailty syndrome in the hopes of altering the prognostic trajectory of this clinical sample. This protocol serves two purposes: 1. It tests the feasibility of recruiting and retaining frail older adults with depressive symptoms in a treatment trial, and 2. It provides pilot data for the effectiveness of an antidepressant medication on treating the characteristics of frailty and the comorbid depressive symptoms.

Experimental: Medication Treatment
Participants are treated with a flexible-dose antidepressant medication for a period of 8 weeks.
Drug: Antidepressant Medication
If patient has a history of non-response or cannot tolerate escitalopram and/or duloxetine, then they will be treated openly with an approved antidepressant.
