Quantitative EEG Markers in Mild Cognitive Impairment: Degenerative versus Vascular Brain Impairment

Figure 2

Statistical ANOVA interaction among group factors and relative band powers (delta, theta, alpha1, alpha2, and alpha3), on the full scalp region. The groups are based on mean and standard deviations in a normal elderly sample. Group 1: no hippocampal atrophy; group 2: mild hippocampal atrophy; group 3: moderate hippocampal atrophy; group 4: severe hippocampal atrophy. Post hoc results are indicated in the diagram (see [32, 35]).
