What is dementia?<br />

A pers<strong>on</strong> with dementia will usually<br />

experience a progressive decline in their<br />

mental abilities because of damage to the<br />

brain. This damage may have many causes,<br />

including Alzheimer’s disease, vascular<br />

dementia and Lewy body dementia.<br />

The signs and symptoms of dementia include<br />

memory and communicati<strong>on</strong> problems, difficulties<br />

in daily living, changes in mood and behaviour, and<br />

the gradual loss of c<strong>on</strong>trol of physical functi<strong>on</strong>s.<br />

However, we are beginning to understand how<br />

much people with dementia can still do and<br />

experience, despite the effects of their illness.<br />

About 700,000 people in the UK currently have<br />

dementia and this is likely to increase to 1.7 milli<strong>on</strong><br />

by 2051. Older people are more likely to develop<br />

dementia – <strong>on</strong>e in five of us by the age of 85.<br />

However, some younger people develop dementia<br />

too. <str<strong>on</strong>g>Dementia</str<strong>on</strong>g> costs the UK over £17 billi<strong>on</strong> a year.<br />

Even with the best support, a pers<strong>on</strong> with dementia<br />

will usually experience significant changes in their<br />

life as a result of their declining mental abilities.<br />

These may lead to <str<strong>on</strong>g>ethical</str<strong>on</strong>g> problems for the<br />

individual with dementia, for family and friends<br />

who provide unpaid care and support (described as<br />

‘carers’ in the report), for those providing paid care<br />

(care workers and professi<strong>on</strong>als such as doctors),<br />

and for society as a whole.<br />

There are no easy answers to these problems,<br />

but the aim of this report is to suggest<br />

ways of approaching them.
