Interpretation 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 controls
