The pattern of dementia risk is different in young-old and oldest-old people


  • Dementia risk increases with age: although at a slower rate than in young-old people (older people younger than 80), the risk of dementia does continue to rise in people of extreme old ages (people aged 80, 90 years, or older).

Why this matters

    This study summarizes the pattern of dementia incidence in people of different ages and highlights that findings from dementia research focused on people younger than 85 may not be generalizable to people of extreme old ages.
