So... my mom is in the ER. I get a call from my dad saying that he found her sitting on the couch, aphasic, agitated and seemingly blind. He was only gone from the house an hour and a half. So, naturally he called an ambulance and gave me a phone call.

I rush down to find her fighting with the nurses, aphasic and sporting a fever of 102 with a pulse of anywhere from 120-135. Lowest I saw was 118.

My educated guess was infection that's now affecting her brain. The two admitting doctors taking over her care seems to be thinking the same.
