Description

The image on the bottom shows a portion of the record where we can see a slow frequency evolution, most prominent on highlighted channels. We are unsure whether to consider this a seizure because though it constitutes a clear change from background, the frequency remains slow and the discharges are not very sharp. The image on the top shows the portion of the record directly preceding this event.

Question

1. Should the slowly-evolving event shown in the images above be considered a seizure?
