Now, a watch containing a sim card has been developed for dementia patients so they can be located by carers or family members using their phone or computer if the person becomes confused.
The Vega watch, created by Finnish company Everon, is intended to offer greater independence, allowing the wearer to continue with their hobbies, as well as giving peace of mind to family members, who can track them from space.
Relatives can go online to see a map with a marker showing where the wearer is at any given moment, as well as setting safe boundaries that, if strayed beyond, triggers an alert from a monitoring centre that is manned 24-hours-a-day.
An emergency button on the watch enables the wearer to alert those at the centre, who will send help to the location.
