Comparing the Efficacy of Two Cognitive Screening Tools in Identifying Gray and White Matter Brain Damage among Older Adults

Table 5

Brain magnetic resonance imaging volumetric quantification of older adults (N = 90) with no cognitive impairment (NCI), mild cognitive impairment (MCI), or moderate cognitive impairment (MoCI) also screened by the Montreal cognitive assessment (MoCA).

Brain tissue-specific and region-specific abnormalities	NCI (n = 32)	MCI (n = 13)	MoCI (n = 45)
	Mean ± SD	Mean ± SD	Mean ± SD
Periventricular white matter (cm^3)	1.06 ± 0.80	1.08 ± 0.64	1.33 ± 1.00	0.367
Deep white matter (cm^3)	1.09 ± 0.86	1.00 ± 0.71	1.24 ± 1.00	0.625
Parietal atrophy (cm^3)	0.84 ± 0.72	0.46 ± 0.66	0.84 ± 0.71	0.201
Medial temporal lobe atrophy (cm^3)	0.63 ± 0.80^A	0.54 ± 0.52^A,B	1.09 ± 0.97^B	0.029
Global cortical atrophy (cm^3)	0.87 ± 0.80	0.69 ± 0.75	1.00 ± 0.83	0.458

Indicate statistically significant values. Means ± standard deviation (SD) with different letters represents statistically significant values () in the comparison between groups according to the Tukey’s post hoc test.
