Higher cognitive activity was associated with a higher baseline cognitive function. The ongoing cognitive activity was associated with less decline in working memory and less decline in perceptual speed; not that people don’t decline but they decline less than other people who were not functioning as well earlier in life. And then controlling for age and education and gender they found that a lower level of cognitive activity predicted faster cognitive decline and probably most provocatively, that the risk of developing Alzheimer’s disease decreased by 33% for each additional point on their scale of reported cognitive activity. That didn’t work for the other things they measured, it was the cognitive activity that again this engagement in novel activity that seemed to be the predictor of a reduced level of risk for Alzheimer’s disease.
