Alzheimer's Progresses Faster in Educated People 226

Posted by Zonk from the dumber-they-are-the-softer-they-fall dept.
Nrbelex writes "Bloomberg news is reporting that 'High levels of education speeds up the progression of Alzheimer's disease, according to a study published in next month's issue of the Journal of Neurology, Neurosurgery and Psychiatry. Mental agility dropped every year among Alzheimer's disease patients with each additional year of education, leading to an additional 0.3 percent deterioration, the researchers from the Columbia University Medical Center in New York found. The speed of thought processes and memory were particularly affected.'"

        Please don't mistake education for intelligence.

        This study is really saying that in cases where people have been socially conditioned for a longer period of time are better able to fend off Alzheimer's for longer periods.

        Genius is usually associated with strange social behavior or thinking and just a step away from madness. Educated people are predictable and controllable and well...social.

        They are just more structured, maybe that structure just helps them hang on a bit longer before they fall. I get the feeling that all the commentators are mistaking "knowing things" with being intelligent.

        Actually it seems to be a little weirder than that. [bbc.co.uk]

        The researchers said one possible explanation is what has been dubbed the "cognitive reserve" theory.

        This holds that highly educated people either have a greater number of nerve connections in their brains, or the nerve connections that they have are more efficient.

        Therefore, when the damaging changes associated with Alzheimer's - such as the deposition of toxic protein clumps - start to take place, educated people are better placed to resist their effect at first.

        However, the subsequent impact is likely to be greater than it would be in less educated brains, because of the higher levels of accumulated damage.

        In other words (I think), educated people simply don't show the effects of Alzheimers as fast. By the time anybody notices that anything is wrong, a great deal of damage already exists. So since it is already at a later stage when you first notice it, it looks from the outside as though the person has very quickly reached an advanced stage of Alzheimers. Instead, they have been resisting Alzheimers for ages.

        There was a New Scientist article about this...

      From Bloomberg UK: Previous studies have shown that people with high levels of education are less likely to develop Alzheimer's disease. The new study shows that the brains of more educated people can tolerate changes for longer periods of time, meaning signs of decreased mental agility typical of Alzheimer's disease appear later. When those signs do appear, the disease progresses faster than it does in less educated patients.

      So the results of this one study don't mean much. If all previous research shows the opposite, then either a) this study is flawed and the conclusions inaccurate or b) this study uses new methodology, breaks new ground, and has discovered a new series of conditions for Alzheimer's propogation. The results won't be conclusive until more studies of this same type are produced verifying these results.

    • The most worthwhile comment so far on the whole thread.

      The previous studies have shown that people with high levels of education are less likely to develop the disease, which was interesting and a bit mystifying.

      This study shows that perhaps that's not really what's going on. Perhaps something about education that makes you more resistant to the disease and more able to compensate for the slow decline it induces, but once you do start declining, it happens faster. The two studies together make a lot of sense and point to a mechanism. Either taken alone seems a bit strange.

      • I agree. Sounds like a misleading study. Mental agility is hard to measure across populations with simple tests - even when educated people start to lose a little, they often still perform well in tests as they have more 'reserve'. I imagine that there's probably a great deal of similarity in the amount of brain cells lost, but that the educated can continue to perform well in the tests as they can compensate. In the later stages of the disease, their reserve is exhausted and they decline faster. This agree

    This is interesting. I would love to see a comparison between those with traditional American educations (which I assume is what this study focused on) and those who are similarly capable (perhaps who hold similar titles in similarly challenging fields), but who have followed less traditional paths in learning.

    For example, I can point to five people at my current job - each a very skilled software engineer, and each very skilled in debating other topics in current events; among those five people are 1 PhD, 2 Masters, 1 college drop-out, and 1 high school drop out. The one thing we all agree on? Much of traditional American education has become primarily a matter of rote memorization - there is very little teaching of theory and problem solving involved.

    Further, I saw a different study some years ago that showed a strong correlation between studying the arts late in life and delaying the onset of Alzheimers. Proficiency in the arts tends to require lots of understanding of abstract concepts, akin to studying theory in more technical fields, and requires little rote memorization.

    That is to say, is it possible that the study hit on people whose minds have become less plastic as a result of education? People whose brains have been conditioned to be crystalizable by massive repetition instead of adaptable to new situations? Or, to take the nature instead of nurture angle, was the study skewed heavy on people with more crystaline brains, because such people are more proficient in an educational environment heavy on rote memorization?

  • Fortunately, several potential treatments for Alzheimer's are currently being developed, and a few are in trials already. eg. Elan's AAB-001, and AAC-001. We can but hope that this terrible disease will soon be defeated.

    It's not that the disease progresses quicker, it is only after diagnosis it progresses quicker. This probably means that on average the disease starts at the same time but that it manifests itself earlier in 'uneducated' people.

    A theory is that educated people can 'route' around the disease better, so don't display external symptoms. Their education leads, on average, to them having more connections in their brain. However, a critical point i

  • This kind of statistical propoganda is ludicrous. It just goes to show you ... um ... um ... what was I saying? What were we talking about? Where am I? Who are you?
  • All the people in the study were over 65. That means around 40 or so years had passed since they graduated. That's a lot of time to turn into a potato.

    Just because you went through school in your 20's doesn't mean you keep on using your mind. From knowing some of the kids I see going to university today, I'd say there is very little proof that it means people use their minds during school. Heck, George Bush is an ivy league graduate, and it is very likely that he suffered brain damaged from all his booz

    They said:

    1. People with more education develop Alzheimers later; and
    2. People with more education take longer to deteriorate due to Alzheimer's but progress thru the symptoms faster.

    Based on the data (and there is no truth to me having a stack of Alzheimer's patient data and control data on my desk ... ok, maybe there is, but I'm NOT a PhD in the field, nor am I an M.D.), we could correctly visualize it this way:

    A. If you are highly educated, you may (or may not) have a long way to fall before your symptoms become obvious to others - the tests we have measure your abilities to do various tests, remember things, all kinds of stuff that you may develop strategies to compensate for given higher education (or don't develop strategies).

    B. If you start with a high level of ability, you have a longer way to fall before unable to complete tasks, but if the disease affects your neural pathways (and it does, and we do need more brains, so we can study that, got one to spare?) then going from 200 to 150 to 100 to 50 to dead is similar to going from 100 to 75 to 50 to 25 to dead. Same time, sharper fall. However, you may be more capable for a longer time. Note, I did not say IQ, but ability - not the same thing at all.

    Again, to get the real answers, you should read the original paper as published in the original scientific journal.

    But, in the end, seems the best thing you can do is:
    a. get some exercise, even if just gardening or walking to the grocery store to buy milk;
    b. increase your mental abilities, because then if you do start failing, you'll be capable much longer, which is better;
    c. realize that you have less than a 5 percent risk around 60-70 and a 20 percent risk around 90+
    d. you'll probably die from the massive storm caused from Global Warming kicking up the power on your Sunset cruise in the Caribbean when you retire anyway, so this is all moot.
