The accelerated aging of the Chinese population is posing a public health challenge. DuCA is suited for large-scale cognitive screening in primary care, saving time and eliminating the need for extensively training assessors. ConclusionĭuCA-Part 1 would aid rapid screening and supplemented with the second part for a complete assessment. DuCA-part 1 and DuCA-total’s ability to discriminate AD from MCI was 0.84 and 0.93, respectively. At different education levels, the AUC was 0.83–0.84 for DuCA-part 1, and 0.89–0.94 for DuCA-total. The correlation coefficients of DuCA-total with ACE-III and MoCA-B were 0.78 (P < 0.001) and 0.83 (P < 0.001), respectively. The correlation coefficients of DuCA-part 1 with Addenbrooke’s Cognitive Examination III (ACE-III) and Montreal Cognitive Assessment Basic (MoCA-B) were 0.66 (P < 0.001) and 0.85 (P < 0.001), respectively. The correlation coefficient between DuCA-part 1 and DuCA-total was 0.84 (P < 0.001). To improve performance, the DuCA combines visual and auditory memory tests for an enhanced memory function test. In total, 1,772 community-dwelling participants were recruited, including those with normal cognition (NC, n = 1,008), mild cognitive impairment (MCI, n = 633), and Alzheimer’s disease (AD, n = 131), and administered a neuropsychological test battery and the DuCA. We designed a brief and flexible two-stage cognitive screening scale, the Dual-Stage Cognitive Assessment (DuCA), for cognitive screening in primary care settings. ![]() ![]() Aging population has led to an increased proportion of older adults and cognitively impaired.
