How are they affecting you? I think my father is going into a later stage. He is losing the ability to get to the bathroom in time. He keeps opening and closing his mouth and curling his tongue. He is also falling. I dont know if he needs different medication or if there is anything?
Usually the incontinence, yes, is late middle to end stage.
As to end stage, given how they try to keep us alive and walking pill-boxes, it can go on a long time.
Do discuss all of this with the doc.
Good luck.
