Cognitive processes related to gait velocity: results from the Einstein Aging Study.

摘要: The authors examined the relationship between cognition and gait velocity, performed with without interference, in elderly participants. Neuropsychological test scores from 186 cognitively normal elders were submitted to factor analysis that yielded 3 factors: Verbal IQ, Speed/Executive Attention, Memory. Regression analyses revealed these factors significant predictors of variance but varied as a function task condition. All predicted velocity interference. However, Attention Memory not IQ interference These findings suggest cognitive may have both shared independent brain substrates. Future studies should explore dementia falls.
