My father had been diagnosed with Alzheimer's 5 years ago. He is still very functional but does not cook and needs cuing to shower. There are six children so someone is with him always. My Dad is very lucid all day but is a sundowner and becomes completely forgetful of the days events and the person who were with him earlier. Before he goes to bed he asks where my Mother is. On one recent occasion I told him she was in heaven. It was like he heard it for the first time even though he has dealt with it well during the day. He was so sad, cried for hours and even made statements that he was thinking of killing himself. It was painful to see him grieve so inconsolably. Two days later he asked again where Mom was. This time I told him that she was in the hospital being treated for pneumonia. He was obviously very concerned and asked why he had not been in to see her . I told him he did see her and would be going in again. He was fine with this answer and told me to say a prayer for her, went bed and slept soundly through the night. It is my feeling that I while he is sundowning he can not thoroughly process and I am only causing him more harm and pain. During the day when he is clear and lucid I will always tell him the truth about my mothers death . Please give me some feedback as I have siblings who feel we should be truthful and help imprint my mothers passing at all times.
