Clinical Characteristics and Plasma Cortisol Concentrations in Elderly Subjects With and Without Dementia of the Alzheimer Type

Group	CDR 0	CDR 0.5	CDR 1
N	21	23	10
Age (years)	77.6 (9.7)	74.2 (7.5)	76.0 (4.6)
Sex (M/F)	7/14	15/8	4/6
Sum-of Boxes	.07 (.18)	2.17 (1.00)	6.50 (1.68)
Temporal Factor	1.42 (.80)	.72 (.80)	−.78 (.41)
Frontal Factor	.49 (.71)	.34 (.66)	−.41 (.88)
Parietal Factor	.78 (.32)	.62 (.51)	−.17 (.62)
Cortisol (μg/ml)	14.26 (4.10)	15.08 (3.13)	17.98 (4.29)

Values for all variables, except for N and Sex, are group means (SD). For age, Sum-of-Boxes, Temporal Factor, Frontal Factor, and Parietal Factor, the assessments conducted closest in time to the time of plasma cortisol sampling were used to calculate the group means.
