I'm very confused. My Mum who is 87 was diagnosed last Nov with Alzheimers and Vascular Dementia. She has been on a short but very rapid downhill pathway. She is just over 6 stone. However, the last 3 weeks, she seems to be in a cycle of a good day every 6 where she is lucid, wants to get out of bed, and I can get her to eat and drink as much as possible. Then she fades, doesn't want to get out of bed, is exceptionally confused and shows a lot of the symptoms of late stage Alzheimers. Does anyone have any similar experiences. It's a hateful condition, as these spikes give me huge hope, only to be dashed again usually within 36 hours.
