Table 2.

Mean baseline cognitive scores (SD in parentheses) and annual rate of change (standard errors in parentheses) of cognitive variables by baseline cognitive status

Baseline cognitive status
Cognitive variable Assessment CDR = 0.0, n = 58 CDR = 0.5, n = 34 CDR ≥ 1.0, n = 11
Memory Baseline 107.1 (15.5) 80.4 (17.1) 65.5 (12.6)
Average change   0.14 (0.36)  −0.62 (0.58)  −2.33 (1.14)
Executive Baseline  98.4 (12.1) 85.7 (19.3) 80.0 (20.6)
Average change  −0.36 (0.28)  −0.44 (0.44)  −4.62 (0.86)
Time cognitive, y First to last    5.6 (1.3–9.0)   3.8 (1.1–7.2)   3.4 (1.5–6.1)

The average time between the first and last cognitive evaluation (range in parentheses) is presented by cognitive status. Annual change is in standard score points (mean = 100, SD = 15).

CDR = Clinical Dementia Rating score.
