Post-mortem subject demography.

	AD	HC	𝑃 value
	(𝑁=30)	(𝑁=27)
Age (years)	78.0 (9.2)	77.0 (7.6)	>0.05
Gender females (%)	27	33	>0.05
ApoEε4 carriers (%)	76	15	<0.0001
PMI (hours)	33.9 (22)	38.4 (14.3)	>0.05

Values are means (SD) unless noted above as otherwise. 𝑃 values were calculated using 𝑡-test (two tailed). HC: healthy control, AD: Alzheimer’s disease, ApoEε4: Apolipoprotein E epsilon 4, PMI: postmortem interval.
