We've both just done our Powers of Attorney,for finances and Health and Welfare - the latter includes a section for any particular preferences.
Having seen far too much of dementia in all its stages, I feel very strongly about this, so here's what I put in mine.
'.1). In the event that I develop dementia, , or any other condition where I am unable both to care for myself and speak with capacity for myself, then with the exception of fractures, I do not want any interventions, whether surgical or medical, intended to,prolong my life or keep me alive when I would otherwise die. I ask for palliative care only.
2). In the event of my needing full time care because of dementia or any other reason, I do not want any of my family to have the burden of looking after me. I want to be placed in a good care home as soon as my care becomes at all difficult or stressful for family members.'
