Primary Outcome Measures:
  • 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".

Secondary Outcome Measures:
  • 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.

Enrollment: 131

Study Completion Date: July 2009
Primary Completion Date: July 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Participants will receive sertraline at a target dose of 100mg daily.
Drug: Sertraline (Zoloft)
Sertraline: range of 25 to 125 mg per day for 24 weeks
Placebo Comparator: 2
Participants will receive placebo matched to sertraline
Drug: Placebo
Placebo designed to mimic sertraline taken daily for 24 weeks

Detailed Description:
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.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No


  • Ability of the participant, caregiver or surrogate to provide written informed consent.
  • Dementia due to Alzheimer's disease
  • Stable treatment for Alzheimer's disease
  • Ability for the participant's caregiver to accompany the participant to study visits and participate in the study.


  • Presence of a brain disease that might otherwise explain the presence of dementia
