Youthful Processing Speed in Older Adults: Genetic, Biological, and Behavioral Predictors of Cognitive Processing Speed Trajectories in Aging
Objective: To examine the impact of genetic, inflammatory, cardiovascular, lifestyle, and neuroanatomical factors on cognitive processing speed (CPS) change over time in functionally intact older adults. Methods: This observational study conducted over two time points, included 120 community dwelling cognitively normal older adults between the ages of 60 and 80 from the University of California...
متن کاملTrajectories of combined laboratory- and real world-based speed of processing in community-dwelling older adults.
OBJECTIVES To characterize the trajectories of laboratory- and real world-based speed of processing (SOP) over 5 years using finite latent growth mixture modeling, and to explore associated baseline individual-level predictors and functional outcomes in 2,802 community-dwelling older adults from the Advanced Cognitive Training for Independent and Vital Elderly cohort. METHOD Laboratory- and r...
متن کاملAre processing speed tasks biomarkers of cognitive aging?
We examined the association between 5 processing speed measures and general cognitive ability in a large (>900) sample of relatively healthy men and women at age 70. The processing speed tests were the Wechsler Digit Symbol-Coding and Symbol Search, simple reaction time, 4-choice reaction time, and inspection time. To inquire whether the processing speed tasks might be biomarkers of cognitive a...
متن کاملSpeed of processing in older adults: a cognitive overview for nursing.
With advancing age, subtle declines in various cognitive abilities occur. One ability that is particularly important as people age is speed of processing. Speed of processing is suggested to impact other cognitive abilities; in fact, some studies suggest that other cognitive abilities depend on speed of processing as a foundational cognitive resource. Studies also indicate that declines in spee...
متن کاملCognitive Flexibility, Attention and Speed of Mental Processing in Opioid and Methamphetamine Addicts in Comparison with Non-Addicts
Introduction: Many studies have revealed that drug addicted individuals exhibit impaired performance on executive function tests but a few studies have been conducted on executive functions of drug addicts in Iran. To contribute to this understanding, the present study was designed to assess some domains related to executive functions including cognitive flexibility, attention and speed of men...
