Idea density measured in late life predicts subsequent cognitive trajectories: implications for the measurement of cognitive reserve.
OBJECTIVE The Nun Study showed that lower linguistic ability in young adulthood, measured by idea density (ID), increased the risk of dementia in late life. The present study examined whether ID measured in late life continues to predict the trajectory of cognitive change. METHOD ID was measured in 81 older adults who were followed longitudinally for an average of 4.3 years. Changes in global...

متن کاملCognitive Reserve in Dementia: Implications for Cognitive Training
Cognitive reserve (CR) is a potential mechanism to cope with brain damage. The aim of this study was to evaluate the effect of CR on a cognitive training (CT) in a group of patients with dementia. Eighty six participants with mild to moderate dementia were identified by their level of CR quantified by the CR Index questionnaire (CRIq) and underwent a cycle of CT. A global measure of cognition m...
متن کاملGenetic Risk Score Predicts Late-Life Cognitive Impairment
Introduction. A family history of Alzheimer's disease is a significant risk factor for its onset, but the genetic risk associated with possessing multiple risk alleles is still poorly understood. Methods. In a sample of 95 older adults (Mean age = 75.1, 64.2% female), we constructed a genetic risk score based on the accumulation of risk alleles in BDNF, COMT, and APOE. A neuropsychological eval...
