RAND research has found that cognitive ability, physical health, and functional limitations can predict the risk of developing dementia, with lifestyle factors such as exercise and hobbies influencing the likelihood of developing the disease. Early detection of cognitive impairments can help individuals prepare for future financial and physical challenges. The study also found that out-of-pocket costs are a major barrier to seeking cognitive assessments and treatment for dementia. Increasing access to cognitive testing could help identify those at risk for dementia and facilitate action to prepare for the future. Genentech provided support for this research.
