Predictors of Functional Independence in Healthy Aging and Age-related Disease: Lead Investigator: Thomas Kiely Institution : Ray Dolby Brain Health Center/CPMC E-Mail : kielyt1@sutterhealth.org Proposal ID : 748 Proposal Description: Functional independence is one of the most important factors to investigate in older adults. In addition to a diminished quality of life, increased dependence with activities of daily living carries a significant financial burden to the individual and society. It is unclear which cognitive measures best predict functional decline, and if this relationship between cognition and daily functioning differs across diseases (e.g. Alzheimer???s disease, cerebrovascular disease, Parkinson???s disease, frontotemporal dementia). Although cognitive impairment is one of the most important factors impacting functional independence, there is not a perfect relationship between a patient???s neuropsychological results and their functional status. In addition to cognition, multiple variables can contribute to an individual???s functional ability including neuropsychiatric symptoms, sensory abilities, health conditions, perceived cognitive ability, and social engagement. If we can better characterize which factors contribute to functional change, we may be able to intervene to attenuate or delay this decline preserving functional independence, even in the short-term, has significant economic consequences and may improve quality of life.
