Purpose
The primary objective of this study is to conduct a randomized, controlled trial to determine whether engaging in mental activity or exercise, either alone or in combination, improves cognitive function in non-demented, inactive older adults who self-report a recent decline in memory or thinking. In addition, we, the researchers at the University of California, San Francisco, plan to seek funding to follow subjects over time to determine whether these interventions are associated with changes in rate of cognitive decline or risk of dementia after the intervention period has ended.

| Arms | Assigned Interventions |
|---|---|
|
Experimental: Aerobic exercise
Study-specific group exercise classes include 10' warm-up, 30' cardio, 5' cool down, 15' stretching/toning. Target heart rate is 60-75% of maximum. Study participants attend classes 60 min/day, 3 days/week for 12 weeks.
|
Behavioral: Group 1
Aerobic exercise plus computer-based mental activity training: both 3 days/week, 60 minutes/session for 12 weeks.
Behavioral: Group 2
Aerobic exercise plus educational DVDs: both 3 days/week, 60 minutes/session for 12 weeks.
|
|
Active Comparator: Stretching/toning
Study-specific stretching/toning exercise classes include 10' warm-up, 40' stretching/toning, 10' relaxation. Participants attend classes 60 minutes/day, 3 days/week for 12 weeks.
|
Behavioral: Group 3
Stretching/toning exercise group plus computer-based mental activity training: both 3 days/week, 60 minutes/session for 12 weeks.
Behavioral: Group 4
Stretching/toning exercise group plus educational DVDs: both 3 days/week, 60 minutes/session for 12 weeks.
|
|
Experimental: Computer-based mental activity training
Computer-based visual and auditory stimulation training programs developed by Posit Science corporation. Participants perform assigned mental activity on computers in their homes for 60 minutes/day, 3 days/week for 12 weeks.
|
Behavioral: Group 1
Aerobic exercise plus computer-based mental activity training: both 3 days/week, 60 minutes/session for 12 weeks.
Behavioral: Group 3
Stretching/toning exercise group plus computer-based mental activity training: both 3 days/week, 60 minutes/session for 12 weeks.
|
|
Active Comparator: Educational DVD training
Watching and listening to in-depth, college-level lectures on art, history and science on the computer. Participants perform assigned mental activities 60 minutes/day, 3 days/week for 12 weeks.
|
Behavioral: Group 2
Aerobic exercise plus educational DVDs: both 3 days/week, 60 minutes/session for 12 weeks.
Behavioral: Group 4
Stretching/toning exercise group plus educational DVDs: both 3 days/week, 60 minutes/session for 12 weeks.

Detailed Description:
SPECIFIC AIMS AND HYPOTHESES
Aim 1: To determine whether a 12-week, computer-based mental activity program improves cognitive function in non-demented, inactive elders.
We hypothesize that this mental activity program will improve cognitive function—especially visuospatial function—in non-demented, inactive elders.
Aim 2: To determine whether a 12-week exercise program improves cognitive function in non-demented, inactive elders.
We hypothesize that this exercise program will improve cognitive function—especially executive function—in non-demented, inactive elders.
Aim 3: To determine whether the effects of mental activity and exercise are additive or are more or less than the sum of their parts.
We hypothesize that the effects of these mental activity and exercise interventions will be additive.
Aim 4: To determine whether mental activity and/or exercise may slow cognitive decline or lower risk of dementia in non-demented, inactive elders.
We hypothesize that both mental activity and exercise will slow cognitive decline and lower risk of dementia, and that the effects will be greatest when mental activity and exercise are combined.
