Physical exam's bringing up nothing, same as the other day. There's no sign of head injury, his pupil reactions are perfectly normal, no symptoms other than the falling flat on his face... Pulse and blood pressure are slightly elevated, but that's probably due to worry about the whole thing. He says he's been seeing things, has been for a few days now, and when I looked him over the other day, he checked out fine.

Looks like it's time for the MRI, the EEG and the other machines that go ping, but you're better on his brain function.
