Performance of study partner reports in a non‐demented at‐risk sample
The Quick Dementia Rating System (QDRS) effectively screened for impairment in Alzheimer's disease and other dementias (ADRD) in a non-demented sample. Concordance rate between QDRS<sub>CDR</sub> global and Clinical Dementia Rating (CDR) Scale global scores is 70.66%. Memory item discrepancies primarily cause QDRS/CDR global score discordance. Cognitive scores are associated with QDRS/CDR concordances/discordances. Future analyses will explore QDRS relations to ADRD biomarkers.
