Becoming so frustrated with the disease and having a hard time separating it from the person. For the past month my mom is having a hard time understanding days and nights. She keeps the blinds closed and TV off so she falls asleep easily in the afternoon. Periodically get ready for bed after lunch. She goes to bed earlier and earlier at night, but still seems tired all the time. I can't make sense of it and don't have any ideas to help her keep it straght.
