Hi
We were recommended to contact the Care Navigator Services, who work in conjunction with the LA to provide tracker-type devices for people with dementia. (not sure if they have funds to do for everyone but it's not means-tested).
My wife was provided with a Vega "watch". It's a little bit bulky but she is happy to wear it and I take it off at night for her.
It connects to a central monitoring centre run by the company that provided it, called
company name deleted. If she were to go missing, they can pinpoint where she is, using either GPS or the mobile network signal (GSM). It also has an "alert button! which if pressed, contacts the alarm centre and they could talk to her (though with her aphasia, wouldn't be of much use).
It also has a very useful function (though we do not use this at the moment) where the centre can set up a "geo-fence". So in your husband's case, if he is fine going within a certain radius (to the shops etc), this could be set up as the "safe zone". If he were then to get confused and wander further afield, the device would send out an alert to the centre, who would then notify whoever is set up as the nominated contact(s). They would be able to pinpoint where he was and if necessary, speak to your husband.
I am told that the device costs several hundred pounds plus a monthly monitoring fee, if you have to pay for it, but it's worth seeing if your local authority have any similar schemes available?
I've listed the organisations I mention, for information.
