WEDNESDAY, July 14, 2021 (HealthDay News) — A cognitively active lifestyle in old age may delay the onset of dementia in Alzheimer disease (AD) by as much as five years, according to a study published online July 14 in Neurology<\/em><\/em>.<\/p>\n Robert S. Wilson, Ph.D., from the Rush University Medical Center in Chicago, and colleagues assessed whether a higher level of cognitive activity predicts older age of dementia onset in AD dementia. The analysis included 1,903 older persons (mean age, 79.7 years) without dementia followed for a mean of 6.8 years.<\/p>\n The researchers found that a higher level of baseline cognitive activity was associated with older age of AD dementia onset (estimate = 0.026). For low versus high cognitive activity (10th versus 90th<\/sup> percentile), the mean onset age was 88.6 versus 93.6 years. Results were similar when adjusting for potentially confounding factors. Among a subset of 695 participants who died and underwent a neuropathologic examination, cognitive activity was unrelated to postmortem markers of AD and other dementias.<\/p>\n “Our research suggests that the link between cognitive activity and the age at which a person developed dementia is mainly driven by the activities you do later in life,” Wilson said in a statement.<\/p>\n Abstract\/Full Text (subscription or payment may be required)<\/a><\/p>\n <\/i><\/p>\n
