I am so sorry, coffee.
Have they put a stint into his brain to relieve the pressure from the swelling? I hope so! I know that taking preventative measures may seem pointless at this point, but I have cared for many wonderful people who had less abilities & they did still find some enjoyment in living life. It isn't easy to accept these changes in life, but it does help a person gain an easier time accepting the end when it does come.
Gentle hugs to you and your family ~ you are in my thoughts.
