Title: The Effects of Mental Activity and Exercise on Cognitive Function in Older Adults Who Self-Report a Recent Decline in Memory or Thinking
Brief Summary: 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.
