Decision-making ability declines in older adults, with changes in analytic and preference factors over time. Cognitive reserve, particularly purpose in life, may influence decision-making changes in aging.
Area of Science:
- Gerontology
- Cognitive Neuroscience
- Decision Sciences
Background:
- Cognitive decline is a concern in aging populations.
- Understanding factors influencing decision-making in older adults is crucial for maintaining independence and well-being.
Purpose of the Study:
- To investigate age-related changes in decision-making ability among older adults.
- To examine the association between cognitive reserve and the rate of decision-making decline.
Main Methods:
- A cohort of 982 older adults without dementia completed decision-making tests annually for a mean of 4.7 years.
- Cognitive reserve was assessed using measures of purpose in life and cognitive activity.
Main Results:
- Decision-making ability showed distinct changes: analytic factor scores decreased, while preference factor scores increased over time.
- Purpose in life was associated with changes in analytic decision-making, and past cognitive activity with changes in decision-making preferences.
Conclusions:
- Decision-making components change differentially in late life and are independently related to age and cognitive reserve.
- Cognitive reserve markers show a mixed but present association with age-related changes in decision-making.
