Hi everyone, My husband is in middle stage Alzheimer's and in the last few months has been getting days when he wakes up and says he feels completely weak and has no energy. All he can do is sit. He is usually slightly better as the day goes on, and is often fine the next day. This appears to happen randomly. The last time it happened, we went to his GP, who seemed totally perplexed and sent him for a blood test just in case it's a virus, but we don't feel it is. Could it be part of the Alzheimer's? Has anyone else experienced this? It would be useful to know, as otherwise he'll probably just keep getting sent for more tests.
