Modfied Alzheimer's Disease Cooperative Study- Clinical Global Impression of Change (mADCS-CGIC) [ Time Frame: Measured at Week 12 ]
At each study visit, based on patient examination and caregiver interview, clinicians rated overall impression of clinical change from baseline using the modified Alzheimer's Disease Cooperative Study Clinical Global Impression of Change index (mADCS-CGIC), which in addition to the original scale incorporates a global rating of mood and associated symptoms of depression. The mADCS-CGIC uses a seven-point Likert scale, with scores ranging from 1 ("much better") to 7 ("much worse"), with a score of 4 being "no change".

Remission According to Cornell Scale for Depression in Dementia Scale [ Time Frame: Measured at Weeks 12 ]
The Cornell Scale for Depression in Dementia (CSDD), a 19-item scale measuring the severity of depression in dementia, utilizing input from both the caregiver and the participant. CSDD scores were imputed for 2 participants for week 2, 4 participants for week 4, 7 participants for week 8, and 12 participants for week 12.

Depression in Alzheimer's Disease (DIADS-2)
The purpose of this study is to learn whether treating individuals with Alzheimer's disease and depression with the anti-depressant medication sertraline (Zoloft) is helpful to people with Alzheimer's disease and to their families and caregivers.
Participants are randomly assigned to treatment with sertraline (range 25-125 mg per day) or identical placebo for 24 weeks. There are 8 scheduled in-person visits in the 24 weeks. Visits include neuropsychological testing. Caregivers are asked to are the patient on a Daily Affect Diary for 6 weeks during the study period. Telephone followup is done at weeks 36 and 48. Both groups receive caregiver support/education.
