Knowing a close friend who lost his father to this, where his father spent many years in care and was always talking crazy. He told me that in the week of his fathers death they were able to talk with each other as adults for the first time in many years. It was surreal because he had long thought the man was lost. I believe the potential cause is an inflammatory response to an unknown agent (bacteria, virus or even our own cells). I wonder if terminal lucidity occurs as the immune system shuts down resulting in temporary reduction in brain inflammation.
