A local company (Lok8u Ltd) has launched a dementia wandering prevention device. This wrist mounted GPS / GSM / RF device may be used in the home and out and about. The main advantages of this equipment is that permits families / carers to become aware when a person with dementia has wandered and then assists in their direct location and retrieval.
A Priority Research Opportunity?
This is innovative technology, so little robust research has been performed yet on its evaluation. Some of the older research on the subject is provided below, discussing the problems of wandering and the promise of technological solutions such as this one from Lok8u Ltd.

Dementia Wandering Prevention Device Available at High Street Chemists
The Freedom product identifies a wandering event and helps to curtail adverse events through the provision of real-time location support to the nominated carer, either from a 24-7 call centre or by email / text message. See more details (other Chemists are available).
Possibly also of interest, there are some impartial guides on Medical Alert Systems (particularly in the North American context).
