Self- and Informant-Report Cognitive Decline Discordance and Mild Cognitive Impairment Diagnosis.

ABSTRACT:

Importance

Subjective report of cognitive and functional decline from participant-study partner dyads can efficiently assess risk of cognitive impairment and clinical progression. Accuracy of self-report subjective cognitive decline may be limited by lack of awareness about one's own cognitive abilities in adults with MCI and dementia, and the extent to which discordance between self- and study partner-report is associated with diagnosis of cognitive impairment is unknown.

Objective

To investigate the association between discordance between self- and study partner-reported cognitive and/or functional decline and MCI diagnosis.

Design, setting, and participants

This multisite, cross-sectional study used baseline data from 2 longitudinal, observational studies. A total
