My husband's doctor asked me if I think the meds are helping. How can you know what it would be like if he was not taking them? Is the quality of his life better? Beats the heck out of me. There seems to be some question as to exactly what these meds do. I will have to discuss this further with his doctor. From what I read, it is supposed to help with cognitive and other emotional issues. Does is still help prevent further damage to the brain? I've read that ultimately death comes when the brain stops telling the body how and when to function and slowly shuts down. Is that true? If so, do the meds prolong the brains ability to control the physical functioning of the body? If so..than doesn't that mean that the meds prolong life? Arghhh. Making decisions for someone u love so much....is an awful part of life. But have Alzheimer's is even worse!!! Wish I had all the ethical and moral questions clear in my heart.
