I am currently working on a paper, i have a population of patients with epilepsy and i would like to divide them according to the weight of seizure activity. every one underwent 10-20 stEEG, most of them did also a 24H eeg.

Many of these patients had 2-3 seizures in their life and are drug responders, thus it is hard to divide them in sub-groups according to seizure frequency.

I was wondering if there is a published reliable method to weight stEEG abnormalities (egs n spikes) in a semiquantitative way.

thank you!
