He needs a what...?

Last Wednesday, something happened twice within a half an hour that has happened before. Joey blanks out. It's the only way I can explain it. He's had them before but I never noticed him having them twice in one day. I did some research later that night and found out that they are called absence seizures. I called his behavioral pediatrician and she said that all though it wasnt' life or death circumstances, she wanted him to be seen right away for a sleep-deprived EEG. Coincidentally, her hubby is a neuro. I called my insurance company today and he was listed as a contracted doc (I later found out that they don't take my plan so it's cash pay). My appointment is set for this Wednesday.
