This does not meet the needs of someone with dementia that cannot remember to leave the device on their person. With that in mind how can it be expected to provide any sort of “net” for those patients (people) living at home with dementia but capable to an extent otherwise. I figured I would give this a try with the sales pitch” we see this all the time”…No you don’t see this all the time because it would not fit the needs of the person purchasing the product. Doesn’t do much good when the necklace is in my sister’s handbag when removed by my dad.. Short of implanting a device, I cannot see how this would work with those people that are forgetful from moment to moment as such.
