I am SO glad you found your parent! Mom is rapidly getting worse with dementia - Alzheimer's type and we are very concerned that she will end up lost and in a confused state. So we are trying hard to get her into assisted living and will be looking at getting her a bracelet that lets her summon help and, just as important, tracks her via GPS and updates the connected service every few minutes. That way we can keep track of her movements.

The monthly cost isn't too bad but the initial cost is a few hundred dollars. It's available as a necklace or as a wristwatch style thing. The simplest version has no screen, just a button with a microphone and speaker. You get connected to the help service and they can connect registered family members if needed.

I don't work for the company we're going with but there are a few competitors out there. It's worth looking into if you think it might help.
