My ratter works with elderly with severe dementia and I do a bit of volunteer work at the residential home where he works too. We have both studied many courses relating to the elderly as well as dementia. To me it is a privilege to be able to spend time with the residents in ratter's care. Sometimes people forget that the person with the dementia is usually unaware that they have it and to them they are still the person they used to be. Quite often they see themselves still in their childhood, still needing to do their homework etc. Behind the dementia live master craftsmen, accomplished dancers, mothers, fathers, teachers, adventurers, successful business men etc. etc. and it is so important that we never forget this. They were once us - and we may one day be like them! Dementia has no age and it doesn't discriminate! Even with people with severe dementia you can often see clearly that the person they were before the dementia is still there, just hidden behind an invisible wall. Rather than think of them as people who are too old or are not worth keeping alive, we owe it to them to respect them and give them the most comfortable life we can. There is no acceptable reason to withhold life enhancing / life prolonging medication from anyone because of their dementia or their age! Just my opinion and I know some will not agree. Maybe it is because you have not had the chance to spend time with people like this, or had the chance to realise that most "old" people actually enjoy their lives.
