My mother has early stages of dementia. We are starting to get worried that someday she will forget how to get home. My father even lost her once at a store. What we are trying to find out is gps trackers for adults or something of that nature. She claims she doesn't have memory problems so we have to be sneaky in using a device. Any suggestions. Please don't suggest taking away the car or anything like that because she is in denial at this point. We are even trying to get her to a doctor but it has been very difficult. The final outcome we would like to achieve is if we can't find her, we would beable to locate her through some kind gps device.
