Incidence of dementia in oldest-old with amnestic MCI and other cognitive impairments.

ABSTRACT:

Objective

To examine the incidence of dementia among the oldest-old people with normal cognition and different types of cognitive impairment.

Methods

This study included 395 participants without dementia (mean age 93.3 years) from The 90+ Study, a prospective, population-based study of aging and dementia in people aged 90 years and older. The participants had evaluations for dementia every 6 months, and their average follow-up was 2.5 years. We examined the incidence of all-cause dementia in participants stratified into 4 cognitive groups: normal, amnestic mild cognitive impairment (aMCI), nonamnestic mild cognitive impairment (naMCI), and other cognitive impairment (OCI).

Results

Dementia incidence was highest for participants with aMCI (31.4% per year) and OCI (39.9
