Abnormal EEG-

A few months ago, my daughter (8) had a sleep study to test for possible sleep apnea. As a result of that test, we were told she had several spikes in her brain while she was sleeping and we were ordered a sleep deprived EEG to follow up. The result of that test showed more spikes. I was told she doesn't necessarily have epilepsy but that she's possibly as risk for it and we were referred back to the neurologist. Because she's considered a new patient, all new patients appointments are scheduling way out right now. The nurse said she was going to talk to the dr (who is on vacation this week) because my daughter needs to be seen right away and they'll have to fit her in as soon as possible. We have never noticed any type of seizure behavior from her. I've conferred with her teachers and they've not noticed anything either. No muscle spasm, no staring off, no tics, nothing. I did do some reading on this site and saw people posting about dizzy/fuzzy spells, so I'm going to gently ask her if that's ever happened to her. I guess my questions are: 1. Is this unusual to have the spikes but no seizure activity? 2. Are there other symptoms that I don't know about that she could have had that I missed? 3. Should I be concerned that they want her in ASAP or is that standard? 4. Most importantly: What questions do I need to make sure I ask at the appointment? I want to make sure I get all the info that I need and usually take pen and paper to appointments. I'm definitely worried but not panicking. Just trying to wrap my head around this and get all the info I can so I don't walk into that appointment unarmed. Thank you!
