How do Alzheimer's patients perceive the passage of time?

Treating Alzheimer's Disease

Prior to now, Alzheimer's condition, its processes, destruction and indicators have grown to be much more well regarded and recognized, although medical practitioners and research workers continue to be not sure what may cause the affliction.
Medicines for example Aricept, Exelon, Razadyne and Namendal are usually put to use to manage the the signs of Alzheimer's, even though they provide absolutely no hope for remedy.

Fetal stem cell studies have already been concentrating on providing hope for comfort of signs or symptoms, enhanced comprehension, body system operations, and an ultimate remedy for several phases of Alzheimer's. Fetal stem cell treatments is targeted on rebuilding or perhaps sustaining particular brain functionality, as well as relieving additional problems for brain cells and nerves. Such regions of research are presently underway in countries from Japan to the Ukraine.

My Dad is always asking what day it is. He'll ask "Is today Thursday" One of us will tell him, "No, today is Saturday." He'll tell us that's not right, it can't be, but eventually believes us. He stands in front of the calendar and looks at the days, usually trying to find out when he has a doctor's appointment. One day he was talking about having to call his place of work to let them know he wasn't coming in. I told him that he hadn't worked in that particular occupation since he retired in 1973, 40 years ago. He said that wasn't possible and asked what year it was. I told him 2013. He couldn't believe that 40 years had gone by. He also worries about what time it is, and says the clocks aren't on the right time!

My grandmother has Alzheimer's and it gets progressively worse. At first, they really need for someone to be there that they know and feel upset when no one is. Later, it is a more "in the moment" sort of thing. By that, I mean you might walk in the room after being gone for an hour and they will take up the conversation you were having as if you never left. Likewise, go to the bathroom for 5 minutes and they will say you've been gone for days. When you are there, they are in the moment with you and enjoy your company but short term memory is lost and it doesn't hold. On the other hand, she can go into detail about her childhood and mine too! Don't worry about it. As long as she has familiar faces around her and people who treat her kindly, she should be okay. In my case, my grandmother moved in with us.

Carol's article is indeed helpful.

Since persons with mid-to-late stage dementia are usually not able to articulate clearly what they are experiencing and feeling, it is really hard to know what a day is like in their experience. I think we just have their behavior as a clue. Have you asked the staff how she seems on the days when you are not there?

My mother seems to have lost all sense of time. When she asks for a cup of tea she wants to know where it is even before I've gotten the water in the kettle. Those few moments must feel like a long time to her. Other times she'll talk about when so-and-so visited yesterday when in fact that person hasn't been around for a few weeks. Those weeks are collapsed into a day in her memory.

I know that my mother likes getting phone calls and letters. But with the calls it is that she enjoys them at the time they are occurring. It doesn't seem to be the case that she savors them the rest of the day or thinks before going to bed, "It was really nice today to hear from 2 of my kids and to get a letter."

If your mother enjoys having you visit when you are there that may be the most you can know. Enjoy it!

The article by Carol Bradley Bursack on this site is excellent.

I do not have any experience with the disease. Hopefully others will respond with hands on experience. Good Luck
