My wife has a friend that was dizzy due to a urinary tract infection. My wife said a relative had one and it got so bad she started seeing aliens. Once the infection was under control the aliens went away. (Now THAT would be scary - if they didn’t go away!)
Oh yeah.... UTI’s can mess up your head big time, especially in older woman.
Did a stint in Geriatric-Mental Health, and if one of the lady’s started decompensating for no apparent reason, that’s the first thing we looked at.
