Cranial magnetic resonance imaging (MRI) revealed hyperintense areas in bilateral hippocampal white matter on the T2 coronal sections (Fig. 1).

An electroencephalogram (EEG) revealed diffuse slow waves and rapid activity (delta brush activity) observed on top of these slow waves (Fig. 2).

EEGs performed intermittently revealed that extreme delta brush activity continued, but this specific pattern was observed only in the frontal regions of bilateral hemispheres at the end of the 8th week, and disappeared and gave way to EEG findings of predominant diffuse slow waves at the end of the 10th week (Fig. 3, 4).
