Study Finds Dementia Risk Factors in People Over 90
A recent study examined dementia risk in people over 90 and found that sex, race, and genetics play a significant role. The study also identified individuals who remained cognitively healthy despite having major risk factors.
A study of people over 90 found that dementia risk remains strongly shaped by sex, race, and genetics. Women and black participants were found to face notably higher risks of developing dementia. This suggests that certain demographic factors continue to influence dementia risk even at advanced ages.
The study also revealed an intriguing phenomenon: some people stayed cognitively healthy despite carrying major risk factors. These individuals may hold important clues to how the brain can resist dementia deep into old age. By studying these cases, researchers may be able to identify new strategies for preventing or delaying dementia onset.

What were the main risk factors for dementia identified in the study?
The study found that sex, race, and genetics were major risk factors for dementia in people over 90. Women and black participants were at higher risk of developing dementia.
Can people with major risk factors still avoid dementia?
Yes, the study found that some people with major risk factors remained cognitively healthy. These individuals may offer clues to how the brain can resist dementia.
What can be learned from people who stay cognitively healthy despite risk factors?
By studying these individuals, researchers may be able to identify new strategies for preventing or delaying dementia onset. This could lead to the development of new treatments or interventions.
Is dementia inevitable for people over 90?
No, the study suggests that dementia is not inevitable for people over 90. While certain risk factors increase the likelihood of developing dementia, some people are able to remain cognitively healthy well into old age.
What are the implications of this study for dementia research?
The study highlights the importance of considering demographic factors, such as sex and race, in dementia research. It also suggests that further study of individuals who resist dementia despite risk factors could lead to new insights and potential treatments.
