Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Regional Cerebral Metabolism | Baseline and 12 months | Changes from baseline in regional cerebral metabolism |
| Secondary | Changes in neuropsychological performance measures | Baseline, 6 months, and 12 months | Changes in cognitive performance over time within each group will be measured through the neuropsychological assessments listed below, as administered by trained psychometrists under direct supervision of a licensed neuropsychologist, and will be correlated with changes in regional cerebral metabolism. |
| Secondary | Changes in neuropsychological performance measures: Mini-Mental State Examination | Baseline, 6 months, and 12 months | Mini-Mental State Examination (Folstein, 1975) |
| Secondary | Changes in neuropsychological performance measures: Wechsler Adult Intelligence Scale (WAIS-III) Digit Span | Baseline, 6 months, and 12 months | Wechsler Adult Intelligence Scale (WAIS-III) Digit Span (Wechsler, 1997) |
| Secondary | Changes in neuropsychological performance measures: Trail Making Test Part B | Baseline, 6 months, and 12 months | Trail Making Test Part B (Reitan, 1958) |
| Secondary | Changes in neuropsychological performance measures: Functional Activities Questionnaire | Baseline, 6 months, and 12 months | Functional Activities Questionnaire (Pfeffer et al., 1982) |
| Secondary | Changes in neuropsychological performance measures: Verbal Memory | Baseline, 6 months, and 12 months | NeuroTrax BrainCare, a cloud-based computer application that includes a series of tests and associated reports, will be used to measure Verbal Memory. |
| Secondary | Changes in neuropsychological performance measures: Non-Verbal Memory | Baseline, 6 months, and 12 months | Non-Verbal Memory (measured using the NeuroTrax BrainCare application) |
| Secondary | Changes in neuropsychological performance measures: Verbal Function | Baseline, 6 months, and 12 months | Verbal Function (measured using the NeuroTrax BrainCare application) |
