My brother, aged 68, has been drinking heavily for at least 10 years. the first time he fell, he suffered a bleed in the brain and was in recovery for 7 months. (six years ago). In the past year, he has quit eating altogether three times, has fallen three times, and is currently in assisted living. His body is healing, but his mind is going. His long term memory is there, but he is saying things that make no sense and has been declared incompetent. Will this ever improve, or no?
