I care for my sister 4 years on from diagnosis of Alzheimer's disease. She lives independently. On one level she is ok. She keeps herself and the house clean. I feel that she is no longer any to do any meal prep, but won't accept help. So I make sure that her fridge is stocked with ready to eat food. Physically she is very fit and goes walking most days. She walks in her local area where she is reasonably well known but she does go off road walking. She cannot use a mobile phone. I have raised the subject of wearing a tracker so that if she got lost she could be found and ditto she can be reached if she has a fall. Has anyone got experience of using trackers that they can share with me?
