Kids are different: The eeg in children is very difficult to interpret. Many adult neurologists do not feel competent to interpret the eeg of children. Those of us who interpret eegs in children do so with caution. You should not even try. Let your doctor decide how important the eeg was, and let him decide what to do about the results. The eeg is a tool to be used by a qualified specialist.

Depends: Xl spike and xl events are computer generated markers on an eeg which may or may not represent epileptic spikes or seizures. Most of the time these are false detections, meaning that the computer thinks there is an abnormality, but there is none. The eeg specialist has to review the eeg recording and make his/her own judgment as to whether there are actual epileptic spikes or seizures.
