Understanding EEG

I need some help understanding my daughter's 24 hour EEG.
What I can gather is that, she is having precursors to seizures during sleep?
Some background, she has Down syndrome and Autism. The report shows the following:
The patient's icteric awake background showed rhythmic 7 to 8 hertz or slightly past 8 hertz, occipital back with occasional sharp waves in drowsy and awake states over the biparietal and posterior temporal regions, next, on the right more than the left.These were sometimes synchronous and occasionally asynchronous over the right hemisphere. With sleep, they became more active. Examples of the drowsy awake state were seen at 17:12:50. Good examples of sleep and drowsy sharp waves predominately over the right hemisphere were seen at 22:35:16 and at 22:35:18. These were seen in a fairly frequent semi conscious fashion at Stage II sleep and also Stage III sleep. Rhythmic runs of this activity that were synchronous in both the parietal regions but sometimes higher amplitude and more seen over the right hemisphere was seen at 17:17:56 and 17:17:59. This activity is fairly frequent throughout all portions of the sleeping record.
The 24 hour EEG showed sharp waves over the right and left parietal and posterior temporal regions with predominant maximal activity over the right posterior quadrant with the right parietal leads being in the maximal areas of sharp waves. This activity was seen most ictal in Stage II and Stage III; less frequently in drowsiness and awake state. This activity did not correlate with any clinical behavioral change to suggest a patten is present in sleep predominately.
The doctor put her on Depakote sprinkles after this. We are now at a dose of 300mg AM and 375mg PM/
What on earth does this mean?? The doc doesn't really explain it
Thanks, Megan
