My wife has suffered an anoxic brain injury. That is lack of oxygen to the brain. has been in the hospital to almost 3 months. I bring her family pictures to help her to remember who her family is. The picture is one of us we have taken in the past. We have been married for 41 years. her short term memory is what has been affected the most. As I show the same pictures to her almost daily she remembers who the grand kids are and other family members. Early in our marriage I would buy little puzzles for her to let her know I was thinking about her. I thought would trigger the same response.
