You have my prayers. I went through a long and difficult journey with my Dad who had dementia. I know this is hard.
It does sound like a stroke, but I’m no doctor. The times my sweet Dad would act up (and his balance/gait problems dramatically get worse), it always turned out to be a subclinical UTI (had to wait for culture, urine looked clean at check, but culture proved otherwise). After antibiotics, he was back to baseline.
I hope and pray the remedy for your precious Dad will be as simple. Hold fast to the Lord, He is with you.
Thank you, and I’m sorry you had to go through this too.
The last time he was “off” was when he lived with us - his doc prescribed an antibiotic even though there was no UTI on the urinalysis. We mentioned it to this doc, and he put him on antibiotic too “just in case”.
