In some circumstances and when appropriate consent is given, GPS tracking can enable a person with dementia to remain independent for longer, providing them and their carer with peace of mind.
But we must balance the potential advantages to the individual and the protection of a person's civil liberties. Any tracking system must support and never replace good quality care.
Alzheimer's Society understands the safety of people with dementia is an important issue to address and people with dementia and carers have told us that they welcome technology like this if used in the right way.
Hughes added that the society is working with organisations such as the Association of Chief Police Officers and the Missing Persons Bureau to ensure people with dementia feel secure and included in their communities wherever they live.
