Comparison of the regional cerebral metabolic rate of glucose values between the multiple system atrophy patients with normal cognition and those with cognitive impairment.

	Right superior frontal gyrus (12, 42, 48)		Right superior frontal gyrus (18, −6, 70)		Right superior parietal lobule (34, −56, 58)
	MSA-NC group	MSA-CI group	MSA-NC group	MSA-CI group	MSA-NC group	MSA-CI group
rCMRglc	110.58 ± 6.17	102.31 ± 7.73	104.04 ± 6.52	94.10 ± 8.93	101.05 ± 6.42	90.55 ± 8.98
p-value	p < 0.001		p < 0.001		p < 0.001

The data are presented as means ± standard deviation. MSA-NC, multiple system atrophy with normal cognition; MSA-CI, multiple system atrophy with cognitive impairment; rCMRglc, regional cerebral metabolic rate of glucose.
