Proposed electronic tagging of dementia sufferers, with their agreement, has been backed by the Alzheimer's Society.
The charity said the plan could empower patients by allowing them to wander, but called for a debate on the ethics of gaining consent.

Many dementia sufferers feel compelled to walk about outside - the society says 60% may wander, and 40% have got lost at some point.

The government has said tagging could allow people to lead "fuller lives".

I think as long as this IS done with the patients consent then it is a good idea. My mum has dementia and although she has not got to the stage where she wanders off I know it will happen eventually.
