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."

      So for those who are mentally engaged, it may take many more years for the symptoms of the disease to appear. But once they do, the course of the disease seems to speed up. Researchers say there's a bit of a silver lining here: knowing that the disease will likely progress more quickly. "We think this is very good news," Wilson says. "It suggests that cognitive activity extends your period of cognitive independence as long as it possibly can." And it will likely shorten the battle at the end of life. This means Alzheimer's patients may be less of a burden to caregivers and loved ones.

      It's probably the case that the mental stimulation is having no effect on the disease itself, but is helping a lot with allowing the effects of the disease to be masked by the increased plasticity of the rest of the brain. In other words, you're going at the same time but you're suffering far less.

      Maybe it's because today's 70-year-olds are more educated than their predecessors were. If we look at what time frames today's seniors verses yester-decade's seniors grew up in we'll find more of the older generation came from times when child labor was more common, education depreciated for the common man, and agriculture families were more common. Fewer kids stayed in school beyond what was required by law (if there were requirements in their state) so they were on average less educated.

      Dementia doesn't get anywhere near the funding it should. There's all these cancer charities -

      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.

      mostly focused on breast cancer

      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.

      whereas nobody appears to care about brain cancer or lung cancer (you don't just get it by smoking),

      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.

      while demetia sufferers need far more support, cost far more time and money to treat, and frankly I'd take prostate cancer over altzheimers any day

      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.
