There's another very brief video on this page where they say there's no prevention and no slowing of progression. They're comparing with other diseases like cancer and heart disease, and when it comes to accepted protocol that most doctors will implement, that may be true.The one-hour documentary will be accompanied by community engagement, education, and social media initiatives that will extend its reach and impact far beyond broadcast – to educate the public about the crisis as well as provide on-the-ground support to help those who already have Alzheimer’s.
But square this: the documentary was done in partnership with the Alzheimer's Association that fairly recently finally began to discuss lifestyle impacts on its website. It will be interesting to see if they fit this into the hour program, but it sounds like the program's intent is to raise awareness of the AD tsunami and funds, and telling people to focus on lifestyle wouldn't be a good way to do that (which isn't to say their primary purpose isn't worthy).
At the end of their page on lifestyle factors the AA cites studies. The first one from June 2015 comes with the following AA commentary:
IMHO the AA and PBS should have done a series that would better educate the public as to why we need to focus on both the modifiable risk factors and the need for vastly expanded research funds and activity. How can they talk about the size of the issue without addressing the lifestyle risk factors that no doubt contribute to this ballooning problem? The effect will most likely cause people to keeping sitting back and waiting for pharma. A few might lift the phone and call their representatives and ask them to support increasing funds.In 2014, the World Dementia Council (WDC) requested the Alzheimer's Association summarize the evidence on the risk factors associated with cognitive decline and dementia. The Association believes there is sufficient evidence to support the link between several risk factors and a reduced risk for cognitive decline and dementia. Specifically, the Association believes there is sufficiently strong evidence, from a population-based perspective, to conclude that regular physical activity and management of cardiovascular risk factors (diabetes, obesity, smoking, and hypertension) reduce the risk of cognitive decline and may reduce the risk of dementia. The Association also believes there is sufficiently strong evidence to conclude that a healthy diet and lifelong learning/cognitive training may also reduce the risk of cognitive decline.
