Structural and Functional Deficits in Patients with Poststroke Dementia: A Multimodal MRI Study

Table 4

Brain regions showing significant differences in GMV and fALFF values among the PSND, PSD, and NC groups.

Region	Hemisphere	MNI coordinate			Cluster size	value
		GMV
Cerebellum posterior lobe	Left	-12	-64.5	-36	417	20.85
Medial prefrontal cortex	Left	-3	70.5	-9	711	24.57
Superior frontal gyrus	Left	-22.5	28.5	60	511	16.01
Superior temporal gyrus	Right	60	-24	21	633	14.91
fALFF
Inferior frontal gyrus	Right	45	3	48	138	11.16

GMV: gray matter volume; fALFF: fractional amplitude of low-frequency fluctuation; NC: normal control; PSND: poststroke nondemented; PSD: poststroke demented.
