Mom was diagnosed and treated for UTI. She has never been diagnosed with dementia, although we know she does get a little confused here and there. She always has symptoms of "sun downers" if she stays over in the hospital. Upon her return home, it has always gone away. This time it's different. It's almost like she is delirious. She started improving several days after returning home, and had a couple of "normal" days but all of a sudden, this morning it's like the switch has been turned on again to the confused state of mind.
