I was going to comment that the things they are suggesting are the expected ones but then realised that might be expected to me because I work in the field. Sometimes it’s easy to take for granted things that you are aware of on a daily basis.
The focus is on reducing the risk of vascular dementia (which makes sense as the causes are more obvious) by maintaining a healthy lifestyle
Maintaining a Healthy Weight
Watching Cholesterol and Blood Pressure Levels
I think there are lots of health issues that could be avoided with those three points so sounds like they are all worthwhile!
Keeping the brain active is another key as well
Anyway, the Alzheimer’s Society have put together a downloadable booklet which explains all these aspects in greater (and more colourful) detail.
It’s a good piece of work and definitely worth a look!
