This unremembered state.

摘要

Dementia is perhaps the cruellest manifestation of ageing, inexorably melting away all that which makes us individual and human. Increased life expectancy in the developed world has raised the incidence of dementia, commonly caused by Alzheimer's disease, and the burden of dementia is serious in developing countries too. Not all old people have or will have dementia, but today more than 1% of the UK's total population does, and the number of people with dementia is forecast to double in the next 30 years.
