Alterness

Your mother-in-law’s alertness is something the doctors should address with you. I remember being so sick, I couldn’t really process things very well at the worst times of the illness. While pain meds can do this, there is also something called institutional psychosis, a brief reaction to being in an environment without the usual stimulations of daily life, that can sometimes be described similarly. THis would be something to probe further with her doctors, since GBS isn’t thought to generally affect the central nervous system (brain).
