(A,B) Multiple pathological waves, such as spikes, sharp, spike-slow, and mixed spike-slow waves, can be seen on electroencephalogram in the bilateral frontotemporal areas, bilateral temporal areas, bilateral midfrontal areas, and bilateral occipital areas (red ovals and red circle). Sharp waves (red arrows) were also visible in the central-parietal area.

Sharp waves were also seen in the bilateral temporal, central-parietal, and occipital areas (red marks on Figure 1).
