[The variability of the number and daily distribution of spike wave seizures in two 24-hour long-term EEG recordings made one shortly after the other].
30 patients suffering from primary generalized epileptic seizures were investigated twice in intervals of 1-7 days by means of mobile long-term-EEG monitoring. The total number of paroxysms showed a variability from 53% to 187%, the time of maximum paroxysmal activity varied in between 2.76 hours to 5.40 hours for the whole group; the results for adults, children and patients with/without antiepileptic medication did not differ much. Our findings suggest, that the results of one single 24 hours long-term-EEG investigation must be interpreted with great caution.
