I also highly recommend that book. I wonder whether I'd consider this a hemispheric situation.
It seems to me like the internal, autobiographic self being disabled, and then upon awakening this self immediately says "wait, discontinuity in the recording ... where was I?" and this feeds back into the rest of the brain creating the confusion.
He wasn't confused the moment before, because his autobiographical self wasn't recording.
For me the main sign is the different behaviour. Left hemisphere is vile, ignorant and selfish. Threatening a doctor with death because he hurt you falls in the being sociopathic bastard category. This is my highly uneducated guess
