Study: Alzheimer's Harder to Spot Past Age 80

Subtle Alzheimer’s Signs in People Over 80 May Go Unnoticed

‘Studies Should Focus on Oldest Old’

Bondi adds that the findings underscore the importance of considering age when testing for Alzheimer’s.

Boston University associate professor of neurology Rhoda Au, PhD, says understanding differences in mental declines as they relate to age will become even more important as better treatments for Alzheimer’s disease emerge.

She adds that because people in their 80s and older have traditionally been excluded from clinical trials, it is not surprising that differences between the older old and the younger old are only now being recognized.

In an editorial published with the study, Au notes that given the aging of the population, researchers must increase their efforts to improve diagnosis, care, and treatment of the oldest old.

“It is clear that the oldest old are different, and that some of the assumptions that we make in younger patients may not apply to these people,” Au tells WebMD.
