Table 2. Clinical seizure semiology and EEG Characteristics.
Seizure characteristics in 19 subjects who have had a clinical seizure since enrollment, by group:
| Seizure Type | Epileptiform Discharges (n=14) |
Normal EEG (n=5) |
|---|---|---|
| Focal seizures (FS) | 3 | 2 |
| Epileptic Spasms (ES) | 8 | 2 |
| Focal seizures + Epileptic Spasms | 3 | 0 |
| Generalized seizures (GS) | 0 | 1 |
|
EEG characteristics 19 subjects who have had a clinical seizure since enrollment: 14/19 (73.6%) had epileptiform activity detected on EEG before the onset of clinical seizures | ||
