I thought people might find the following article a useful read on prevention, published this year in June. I personally don't have an issue if a way forward can be found, but there are significant problems with dementia. A healthy lifestyle, keeping active and a good diet may stem off vascular elements of dementia, but this won't work for all types:
“The global number of people living with dementia is expected to increase to 130 million in 2050. Based on extensive evidence from observational studies, it is estimated that about 30% of dementia cases may be attributable to potentially modifiable risk factors. This suggests that interventions targeting these factors could perhaps delay or prevent the onset of dementia. Since the vast majority of people with dementia live in low- and middle-income countries, such interventions should preferably be easy and affordable to implement across a wide range of health care systems. However, to date, results from dementia prevention trials do not provide convincing evidence that treatment of these risk factors reduces the risk of dementia.”

Its worth reading this article as it works through recent approaches at prevention and delaying dementia, the link is given below and is a free view article
