Not Knowing

It's that not knowing part that is most frustrating.

When my mom came home from the hospital just a few weeks ago, she was so much improved! We were shocked at how well she was doing. Of course one can't be cured of dementia. But her overall ability to walk, talk, follow a conversation, do simple chores around the house, read, etc. had been MUCH improved. Over the last few weeks however, she has slipped back into not being able to walk much, can't follow a conversation, having trouble feeding herself, etc.. So- we take her to her general Dr. and ask, "What is happening?" The Dr. doesn't know. The neurologist doesn't know. The neurosurgeon doesn't know. No one knows for sure. And we are frustrated! How to know what to do? Do we just accept this as a process of aging? Do we keep looking for answers? How do we know when enough is enough? How do we know when to stop and just enjoy these last few times with her? Argh. What to do, what to do?
