Fig. 5From: EEG alpha reactivity and cholinergic system integrity in Lewy body dementia and Alzheimer’s diseaseInterpretation of alpha reactivity changes. Illustration of how a reduction in alpha reactivity can be mainly due to a decrease in eyes-closed alpha power (in AD) or an increase in eyes-open alpha power (in LBD) compared to controls. AD, Alzheimer’s disease; LBD, Lewy body dementia; HC, healthy controlsBack to article page
