Mom has lived with Alzheimer's Disease for over six years. Until recently, she slept soundly through the entire night. She now lies in bed all night talking to herself. She doesn't fall asleep until early in the morning and then wants to sleep all day. Her self-conversations seem to focus on undefined or imagined worries. I assume that this behavior is a product of anxiety which is a common symptom of Alzheimer's Disease. I hesitate to discuss anti-anxiety medications such as Xanax with her doctor because of her advanced age and the attendant risks. Am I being too cautious? After all, her new behavior poses no real health or safety risk.
