Where is this found? I'm convinced all the meds my Dad took through his life is the cause of his Dementia and Parkinson's. If not directluy then his poor sleep from peeing 4-5 times through the night for decades absolutely contributed. I had no idea how many meds he was taking until I cared for him. He'd take a literaly handful of meds at night and then wonder why he had to pee so much. It was his body trying to get rid of the shit. Once I saw that we split up the meds through his waking hours and it helped but he'd already been following the Doc's orders for decades.
