Researchers Find 70-Year-Olds Are Getting Smarter
Pickens writes "AlphaGalileo reports that researchers from the University of Gothenburg, Sweden have found in a forty-year study of 2,000 seniors that today's 70-year-olds do far better in intelligence tests than their predecessors, making it more difficult to detect dementia in its early stages. 'Using the test results, we've tried to identify people who are at risk of developing dementia,' says Dr. Simona Sacuiu. 'While this worked well for the group of 70-year-olds born in 1901-02, the same tests didn't offer any clues about who will develop dementia in the later generation of 70-year-olds born in 1930.' The 70-year-olds born in 1930 and examined in 2000 performed better in the intelligence tests than their predecessors born in 1901-02 and examined in 1971. 'The improvement can partly be explained by better pre- and neonatal care, better nutrition, higher quality of education, better treatment of high blood pressure and other vascular diseases, and not least the higher intellectual requirements of today's society, where access to advanced technology, television and the Internet has become part of everyday life,' says Sacuiu."
it's well documented that staying active in the workforce is good for the brain, at least when compared to the sedentary tv-filled days of most retirees.
todays 70-year-olds are smarter.... because most of them can't afford to retire.

Well they must be getting smarter, they surely can't possibly get any dumber. Being against a public option yet if you try to take away their medicare there'll be hell to pay. I wonder how it is that the stupid seem to often outlive the intelligent.
Stress is a killer, dealing with all the stupid people weakens the smart people and they die sooner. Stupid people are happier and have less stress as they off load it to those smarter than them thus living longer (those that don't win Darwin awards early on). Stupidity has advantages, it is why it will always be with us.
From a quick glance in the article, I couldn't find whether or not the test was the same for the 70 year-olds born in 1900 and in 1930. Classic intelligence tests (IQ tests) need to be 'normalized' every few years, because the general populace is getting smarter. If they used the same test, this is not at all surprising. It would hold for a much wider range of ages
Not to be rude, but at some level there's a limit to what can be funded. Perhaps more could be funded in total and there should be more dementia research funding over cancer research funding. But, I was always under the impression that cancer research got more attention because people were more concerned about children, teens, young adults, middle-aged adults, and pre-seniors all not dying of cancer than someone who has lived a full life having a few years--sadly, mind you--with a much reduced quality of life--a factor that's nearly guaranteed once you're old enough. Beyond that, cancer is a host of related problems which seems much more curable.
I'd attribute that to vanity, honestly, (as mastectomy is a very effective cure) but it could simply be that breast cancer is one of the most easily and early diagnosable cancers. Almost everything else requires an MRI or symptoms to even begin to suspect something is wrong.
At least for brain cancer, I'd imagine it's because a lot of brain cancers are inoperable (in large part because they're so late detected and hence most of the damage is already done), but I agree lung cancer (IIRC, a good 20%+ are non-smoking related) should probably receive more focus/funding. Having said that, since cancer seems to be a serious of very similar ailments, a cure or treatment in one area could quite possible translate very strongly in almost all other areas, so any cancer research should do.
Old age suffers need far more support (costing far more time and money to aid) than almost any other group (babies and toddlers require more) generally, so I don't think treating dementia matters greatly in that regard. As for prostate cancer, odds are good you'll suffer that anyways; it's just likely won't kill you. Truthfully, I imagine dementia research has suffered the same problem as brain cancer research: it's hard to diagnosis early and treatment seems near impossible. In fact, one major thing of recent history is that we can now diagnosis pre-alzheimers with a brain scan, which helps greatly in obtain more certain baselines (people might pass or fail the IQ tests given for other reasons and to pass implies you're already a sufferer) and in even thinking about making a treatment (since the best success rates happen most often pre-symptoms).
In short, I think a major reason for the lopsided funded has precisely to do with those factors that look to produce the best results: longer quality of life in more early and easily treatable diseases (worst case, you can remove a breast, but it's harder to remove most of a lung or a large section of brain and expect good results; and symptomatic dementia patients are unlikely to recover). Thankfully, new research with early detection and drug treatments in dementia may help, but we're simply so early in the field that it's only now I'd expect to see a surge in funding.

Not to mention the fact that you can survive and recover from prostate cancer. My great grandmother had at least 3 strokes before she died. For a while(until she was just too much to handle for them) she lived with my grandparents. They actually had to install a door in the hallway that they could lock, so that at night she could get to a bathroom but couldn't go around the house or, worse, get out of the house. She didn't know people in pictures, she could barely walk, or hardly communicate(I know some of that is different than dementia, but from a cognitive capacity standpoint, they're the same thing). I saw what it did to her and to my grandmother. My great-uncle was also diagnosed with prostate cancer. His went away, but he was recently diagnosed with something that is a precursor of leukemia and is undergoing chemo again. Like you say, I would much rather go through what he's going through than what she did, because while both had the support of our family, he can actually recognize that they're there and that he has a support base.

I am no so sure about that, the brain is a complex organ, it might be possible that if you store more info (knowledge) you also get more intelligent. The brain is not like a memory chip where you store and remove data without actually changing the hardware, the simple fact of memorizing stuff for example changes your brain. Also, memorizing is not a passive activity, usually you (and your brain) are actively involved in the process.
Also, talking from the other side of the equation about intelligence, it's pretty obvious to me that human intelligence is based on knowledge, since you can't have intelligence in the absence of knowledge, then I would guess the amount of knowledge is important too (if nothing else, think GIGO)

My masters adviser was a guy named John Fenn. He's now 93 and still quite active in academia today.
When he was about 70 Yale University tried to forcibly retire the guy. The laugh about this is that about this time he started a course of research into characterization of protein molecules that led to a Nobel Prize, awarded in 2002. Because of the retirement flap he left Yale and is now at Virginia Commonwealth.
So was he smart at age 70? Duh.
I've personally found that one of the biggest advantages of taking a course at a community college vs a big university is that there are more people 30+ years old. In every class, there is a time almost daily that one of these students has insight to offer that they've gained from the professional world (eg. working in the healthcare industry) or their personal lives (having kids makes you a valuable asset to any psychology class :-). There are a lot of things I'd never get to hear or understand if I was just in a classroom full of my peers (college-age kids).
In a non-academic context, I've always been fascinated by the stories I've heard from old folks. It's almost unbelievable the amount of jobs and cities and roles that can be crammed into one person's life. So I imagine I'd see the same principle, but to a greater effect in a class with a few elders in it. I would love to see seniors come to study at my university simply because of how much I think it would benefit _me_.
