Magnetic Resonance Imaging Study of Geriatric Depression
The purpose of this study was to use Magnetic Resonance Images to further our understanding of predictors and markers of treatment response and non-response in geriatric depression. We hypothesized that concentrations of high energy metabolites would be lower in depressed elderly compared to non-depressed.

- HAM-D 17 (Hamilton Depression Rating Scale) [ Time Frame: baseline at study entry week 0 ] [ Designated as safety issue: No ]
This is a depression severity rating scale measuring symptoms of depression including mood, sleep, appetite, energy, motivation, guilt, suicidal ideation, concentration, physical complaints, paranoia, anxiety, effect on daily functioning and awareness of illness.
Scale is from 0 (no depression symptoms) up to a maximum of 66 (severe depression symptoms).
- Geriatric Depression Scale [ Time Frame: baseline at study entry week 0 ] [ Designated as safety issue: No ]This is a depression severity rating scale measuring symptoms of depression. Scale is from 0 (no depression symptoms) up to a maximum of 15 (severe depression symptoms).
- MRS (Magnetic Resonance Spectroscopy) [ Time Frame: at week 13 ] [ Designated as safety issue: No ]

No Intervention: Healthy Controls
Healthy Controls undergo MRI and neuropsychological testing
Depressed subjects receive experimental drug
Oral Sertraline Dosage started at 25 mg a day, with increases up to maximum dosage strength of 200 mg a day.
Duration of treatment was 12 weeks.
