Mom (she’s A Nurse Herself) Signs Of Bell’s Palsy 9/30

Question: Mom (she’s a nurse herself) signs of Bell’s palsy 9/30 (mild) 10/1 facial dropping was severe but went to Dr. the diagnosed Bell’s. Rx her prednisone 60 and vatrex. (Pt. history renal pt. does PD every night, knee surgery in April, high bp especially lately). She took the med. the next day she complained about weird dreams. Went to work they sent her home due to hallucinations, dizziness, unbalanced walking. Went to ER CT was clear. Still said her vision was blurry, speech slurred and in her right mind but saying some funny things. 10/2 woke up couldn’t walk face was more drooped. She was out of it wanted us to hold her face bc it felt funny, keep complaining of feeling like she was on a roller coaster, hallucinations, a lot of talking, grab us and hold extremely tight the XXXXXXX and say “it’s over” could evenly raise arms and legs. 10/3 talking but sound like noises couldn’t understand her, proximal muscle weakness but much strength in hands and feet. Extreme twitching in face. Unstable high bp 200’s/98, low K and MG, UTI, Focal seizures which resulted in a bad seizure. Moved to ICU. 10/2 MRI, MRA was clear 10/3 EEG determined focal seizures. Blood cultures didn’t grow anything within 24 hours. Now she is talking speech is still slurred but talking in her right mind, a little spacy. Has nose tube to take medicines. Doctors 1st decided it was Steroid myopathy, Serotonin Syndrome, UTI. But I don’t understand the speech problem if this is true. She was also taking a over the counter medicine Sam-e for joint pain with Effexor, that’s where they got XXXXXXX disorder. No seizures since 10/4 ( had only 1 that day when she was agitated while giving a bath)
Please tell me what’s wrong with my Mom.
