Of all the senses, it is said that hearing is the very last to go (obviously not the case for those who are already hard of hearing or deaf). There is no scientific proof, even in an unresponsive stage that your loved one can no longer hear. Take advantage of all moments you have with your loved one to express your love and appreciation, even when you think they cannot hear you. Sit at their side and talk to them, share your thoughts and feelings, read your favorite religious passages, read a favorite book, joke about the old times and those memories that touch you most. There have been a multitude of occasions toward the end, in that unresponsive state, that a patient has shown acknowledgment of something that was said. You may hear them mumble, squeeze a hand, open an eye, or even crack a small smile. You may not hear, see, or feel any response but that is O.K. If you have anything to say then say it and know in your heart that it is heard.
