More than 850,000 people in the UK have dementia, which affects one in 14 people over the age of 65 and one in six people over 80. I'll be 72 in two months.
My mother had it and my father struggled to look after her. The strain on him was tremendous as she deteriorated really quickly. Because of this, I've discussed it with my DH (who I met 7 years ago) as I don't want him or my family to have any extra stress when deciding what to do. We both have POA in place.
Peter's wife, in the article, may have been less anxious if she had known she was likely to get dementia.
As someone say in the article: “Also, it might stop me worrying that I have dementia every time I forget something.”
Not sure if I'd would have want the test at a young age but from the age of 60, my answer would have been "Yes".
