At least 750,000 people in Britain suffer from Alzheimer's disease and other forms of dementia. Most are looked after by relatives at home. 'It's like looking after a mentally subnormal 3-year-old child. How can you think of them as your husband? It's just someone that I've got to look after.' Some of these carers use Open Space to talk about their daily heartbreaks and struggles, and how a healthcare system never designed to cope with the problem of dementia has virtually imprisoned them at home.
