My husband has had low blood pressure since first diagnosed with Dementia approx. 8 years ago. The last 2 months we have been battling both low and high pressure. He was put on a low blood pressure medication last June when he began passing out. The doctor told me to check his pressure morning and night and if below 100 to give him a pill. If 100 or above do not give a pill. I have tried that but when I give a pill in a couple of hours his BP shoots up to like 180/100. I don't know what to do!
