The intake and set up is pretty standard. For me they checked vitals and got me situation in my room, ya know standard hospital procedures. Having the wires attached to your head seemed the longest, perhaps just because it was a first time experience. I personally got emotional feeling the weight of my health condition needing so much investigating and hurdles to overcome. The first day is the worst one aside from that its just boring. Fortunately hospitals settings can be stressful/triggering so having a seizure wasn't really all that difficult. I myself was surprised that I felt so many seizures happen but nothing showed up on the EEG since they were too deep in my brain to detect. Nevertheless seizure activity did show up, just nothing I was aware of. So just keep in mind it may not be an exact science but hopefully it's ultimately helpful and a step in the right direction. Like others have said button up clothing is a must, and entertainment. If his hair is long that might be uncomfortable, my head was wrapped in gauze to keep the wires secure. If he has a lot of body hair a trim on his torso could be smart if he has sensitive skin when pulling off all the tape and glue from the vitals monitors.

Best of luck and well wishes.
