Example of EEG-SEP worsening. In the top left panel, SEPs are presented at a precise moment which corresponds to the pink line on the raw EEG image (top right panel), with periodic epileptiform activity shown on the QEEG image (bottom right panel) expressed with the CDSA spectrogram, and on the image showing the temporal trend of SEP amplitude (bottom left panel). Note how a progressive loss of SEPs preceded by amplitude instability follows the periodic epileptiform activity.
