Successful Ageing?
The success in ageing has led to viewing these aged individuals (successful in their efforts) as a “burden” to society
This is especially the case for frail elders suffering from dementia
![Page 16: Dementia End-of-Life Care - palliativepalliative.info/teaching_material/DrBadenhorst_EOL... · · 2011-08-17viewing these aged individuals ... If your mother was dying, would you](https://reader033.vdocument.in/reader033/viewer/2022051723/5aad36997f8b9a693f8e15f4/html5/thumbnails/16.jpg)
Implications of Ageing
Clinical- what interventions achieve what goals: multiple, chronic medical problems
Economic - what is society prepared to spend on the care of the elderly- and who will pay for what?
Ethical- what is the impact on society’s fabric of the decisions that are made?

The dying need the friendship of the heart . . . its qualities of care, acceptance, vulnerability; but they also need the skills of the mind - the most sophisticated treatment medicine has to offer.

Food for Thought
Ageing is the 20th century success story
Goal: increase quality of life not just life expectancy
Individuals with dementia present a special challenge

“the life span of any civilization can be measured by the respect and care
that is given to its elderly citizens and those societies which treat the
elderly with contempt have the seeds of their own destruction within them”.
