Help with my Grandpa - it's urgent!?

Me and my wife did own to rest homes and urinary infection did cause symptoms like this or similar. I think that you just have to wait it out until the results. If it is so he will return to normal. It is a very strange thing how this infection causes this behaviour Give it time I am sure he will be Ok. But I do not know how when they get old that they get a urinary infection. But I would ask the doctor so it will not happen again. But it may just be hygiene problems because of getting old.Good luck. IF YOU GOOGLE URINARY INFECTION YOU WILL RESEARCH IT YOURSELF, IN THE ELDERLY.
