Quantification of total number of neurons and occludin-expressing neurons (positive neurons) in frontal cortex (FC) and striatum (STR) regions in control (5 cases), Alzheimer's disease (AD, 4 cases) and vascular dementia (VD, 6 cases) groups. All values were truncated to two decimals

Group	Region	Total number of neurons						Number of positive neurons
mean			SD				SEM					CE						mean							SD								SEM									CE
CONTROL	FC	23.17	3.14	1.57	6.79	5.58	1.52	0.76	13.65
STR		31.58			4.32				2.16					6.84						1.04							0.08								0.04									4
AD	FC	20.67	4.55	2.27	11	11.25	3.13	1.57	13.92
STR		34.33			4.22				2.11					6.14						18.88							2.76								1.38									7.31
VD	FC	22	5.56	2.78	12.65	11.25	2.71	1.36	12.06
STR		24.8			10.57				4.32					17.78						9.28							8.57								3.5									37.69

SD = standard deviation, SEM = standard error of the mean, CE = coefficient of error (multiplied by 100).
