Qoe, I have friends who had this happen to their mums. Bladder infections can cause alsorts of problems in the elderly. My one friend her mum appeared to have dementia because of it. The other started getting confused and agitated, memory loss etc. Hope the infection got cleared up. I guess a mini bleed could have caused the black out/faint. "unfortunately. I have to show her how to put gas in her car, which completely cracks me up!!! " stop laughing now! cos my son had to show me which hole the windscreen wash went in.
