My Aunt used to have episodes infrequently where she would go into an aroused state hallucinating and physically active with no awareness of her limitations and she was in constant danger of trying to walk or do something she can no longer do. She would go until exhausted and then sleep for days, and recover. These were defined episodes with normal periods of six months or more in between.
Over time the episodes diminished in intensity to days of wakefulness and days of sleep, still hallucinating and attempting to do things she shouldn't try to do because of safety reasons, but with less energy and urgency.
Now the cycle of waking and sleeping is constant. Usually 48-72 hours awake and 24-48 hours asleep. She eats with tremendous appetite when awake, but cannot be roused or take medicine or water when sleeping..
What is this stage of Alzheimer's? Is it a stage? The memory care facility cannot manage her on noc shift because they only have one caregiver on duty for 14 residents. I have to just hope she doesn't fall. I used to try to stay with her at night when she was awake, but I work and can't do that regularly.
Is there more information I could find? We understand she has her own reality and we respect that. She "works" at the bank mostly, and is in a good mood and mostly enjoys her hallucinations. She has a full social life in her world, seeing all her loved ones. But I've not known another elder with this extreme wake and sleep cycle. Can anyone explain this to me? I thought deliriums were separate from dementia, but it seems she is in delirium the whole time.
