Different processes. These days a lot of the time you will do the test they may create a minor report but the main report that gets done by the neuro may not get done for a few days up to a week later. Plus it takes a few days just to do it as the reports are a lot more detailed now. This all stretches it out.

The Neurologist or Epileptologist schedule their appt for 3mos. Or 6mos with their patience . But most of the times every 6 months.
Your Dr. wants to go thru your results and the soonest is the 3mo appt.

Hallo Kevin .. in our experience we learn EEG results be only as good as the one who be reading them .. and neurologists vary in their experience ., if you have this done in clinic with large amount of patients ., they often have one or two dedicated to reading EEGs .. and those doctors may have backlog ., be out of town .. or simply too booked with their own patients .. and not all EEGs be same ., there may be tnose requiring inhospitsl stay for a week or more .. infants and children vs adults., these be different to read as well ., and the docs we have encountered want the best for their patients ., so they may ask a colleague with more experience to read it ., to seek another opinion or verify their own .. also time constraints .. prioritizing tnose pending surgery over folliw up checks ., there be a whole host of reasons for a delay ., we find best thing to do is be a squeaky wheel ., call and ask ., if you get put off ., call again .. always be respectful ., and they will check for you ., we understabd those feelings that come .. as all sorts of scenarios come to mind and anxiety soars .. you are just as impirtant as anyone else ., and persistence and patience pay off ., always thank the person you be talking to .. politeness pays off .. we speak from experience ., hope tbis helos a bit ., hugs and prayers from William and Jen 💜💙🤗🤗🕊🕊
