to know which pills did what for him. So I got on WebMD and when I was through he was sort of ok. Last night he had severe sundowners jittery, not knowing what to do with himself and he said he felt like jumping out of his skin. Is this a part of Vascular Dementia? His doc stopped his Lipitor as he said these can cause bad leg cramps. He wanted a beer on the way home so I relented. He ate then went to bed. Are any of these above symptoms Dementia related ? Oh, and no UTI, he was checked. He also had blood work done to see if his potassium is low hence the cramps but he is not supposed to have a lot of potassium because of his kidneys .HELP !!
