DTI and MR Volumetry of Hippocampus-PC/PCC Circuit: In Search of Early Micro- and Macrostructural Signs of Alzheimers's Disease

Table 6

Pearson’s Correlation between MR indexes and cognitive scores.

	MCI (𝑁=10)		AD (𝑁=10)
	Verbal memory	MMSE	Verbal memory	MMSE
Relative BT volume	n.s.	n.s.	0.031	n.s.
Relative WM volume	n.s.	n.s.	0.019	n.s.
MeanFA BT	0.045	n.s.	n.s.	n.s.
MeanMD left hippocampus	n.s.	n.s.	0.048	n.s.
MeanMD left hipp-PC/PCC	n.s.	n.s.	0.029	0.037

Statistical analysis: 2-tailed Pearson’s correlation; 𝑃<.05 is considered significant.
Only significant correlations were reported. MCI: mild cognitive impairment; AD: Alzheimer’s disease; n.s.: not significant; MMSE: mini-mental state examination; Hipp-PC/PCC: hippocampus to PC/PCC tract.
