Many Alzheimer's sufferers are prone to wandering
As a charity comes out in support of electronic tagging for patients with dementia, a carer tells BBC News about her experiences. Denise Linton cares for her husband, Stanley, who has Alzheimer's disease.
A tag would have taken away the worry that I always had when my husband escaped.
Alzheimer's sufferers, at a certain stage in their illness, seem to have an urge to get out.
If you are not aware of them going out it can be very frightening - for the carer, because you don't know where to look, and, probably, for the person themselves because they are in an environment where they're not sure where they are.
You need them to be safe, but it is a kind of compulsion for them to try and get out - they rattle doors.
It's not the fact that you're caging them in at all. It's a normal home environment and they're not aware of the constraints.
Once we went shopping and he went out of the shop.
I just didn't know which way he was going to be going when I got out of the shop. It was very frightening.
I put in more of a substantial gate in our home. But we have a big garden, so he could walk around and having the gate there didn't distress him at all.
His safety is paramount.
I wouldn't want him walking in front of a car and causing accidents. He would be mortified if he thought that he'd done anything like that.
He'd go out in inappropriate clothing.
If the weather is inclement that can cause all sorts of problems.
