Some waveforms or activity on an EEG are normal, while others may be within normal limits for some people but not others. Spikes or sharp waves are terms commonly seen in EEG reports.

WebbSlow spike and wave (SSW) and Generalized Paroxysmal Fast Activity (GPFA) are seen on the EEG. These are the hallmarks of LGS. Diagnosis of LGS requires an EEG test. SSW and GPFA usually emerge between ages 3-5 years but can begin later in childhood. SSW and GPFA, which occur between seizures, worsen seizures, development, and behavior …
