we know a fair amount about prevention of Alzheimer's disease. For example, it begins

as an inflammatory process in the brain so anything that reduces inflammation is protective

and that is why taking ibuprofen everyday reduces risk of Alzheimer's for example. That

is one strategy as an anti-inflammatory diet and lifestyle. We also know that education

is preventive against Alzheimer's disease and dementia and the reason for that seems

to be that education increases what is called neuro redundancy which is duplicative connections

between nerve cells in the brain. So the more connections you've got the more you can afford

to lose before a problem shows up. Are there particular types of education that stimulate

that? I think there are and one I'm sure of is changing your computer operating system

and if you can relate to that particular kind of frustration that comes for a few days when

you've done that and you want everything back the same, you want to put your brain in that

state frequently, that is when neurons are growing new connections. A way to do that

in an ongoing basis is to learn another language. There is very interesting evidence that people

who speak more than one language have better brain function generally and better protection

against dementia. The good news is you do not have to master the language; it's just

the attempt to learn it. It's like running different software through the brain and that's

a good thing to do. So I think there are a lot of strategies of that sort out there that

I think can reduce the chance that you will end up with Alzheimer's disease or dementia.
