Figure 1. Examples of Electroencephalogram Recordings and Magnetic Resonance Imaging Findings.

Figure 1.

Eight electrodes, longitudinal bipolar montage, 20-second epoch, low frequency filter 0.53 Hz, high frequency filter 70 Hz. A, Intermittent slow biphasic delta waves in bifrontal areas, with low-voltage continuous background activity. B, Diphasic and triphasic anterior slow waves, with slow continuous background activity, C, Periodic discharges in the bifrontal areas, with low voltage background activity, D, Bilateral lesions in the supratentorial white matter (arrowhead), hyperintense on axial fluid-attenuated inversion recovery images, E, Multiple microhemorrhages (arrowheads) involving the corpus callosum on T2 star images, F, Left frontotemporal hypoperfusion (arrowhead). ECG indicates electrocardiogram.
