Well done sleepingplum. I did two hours of tests last year as part of a study to guage the affects of stress on the health and cognitive function of spousal carers of people with dementia. It is apparently thought that dementia carers, particularly spouses of people with dementia, are at increased risk of going on to develop dementia themselves, and the boffins are trying to find out why - they are assuming it's the increased stress. So the study I took part in will be tracking several hundred carers over a few years. I agree - there has to be hope to keep us looking forward. And all such research is vitally important.
