Brains Work Best At Age of 39 267

Posted by ScuttleMonkey
from the sounds-like-a-good-last-day-to-me dept.
Scientists at the University of California Los Angeles are reporting that while some people may think "life begins at 40," all it seems to do is slow down. According to recent research, at age 39 our brain reaches its peak speed, and it's all downhill after that. "The loss of a fatty skin that coats the nerve cells, called neurons, during middle age causes the slowdown, experts say. The coating acts as insulation, similar to the plastic covering on an electrical cable, and allows for fast bursts of signals around the body and brain. When the sheath deteriorates, signals passing along the neurons in the brain slow down. This means reaction times in the body are slower too."

      Maybe older people don't take finger-tapping seriously. Maybe younger people are far more likely to have played computer games.

      I met a man who was 55 who told me that he didn't get a good score on a computer pinball game he had just begun playing because he was old. Two weeks later, when I saw him again, he said his score had tripled.

      Quote from the article linked by Slashdot: "Significantly, the research suggests that the myelin breakdown process should also reduce all other brain functions for which performance speed is dependent on higher AP frequencies, including memory; ..."

      That's wild over-interpretation. There is no "should" in science. There is only theory, and it is necessary to emphasize that theories are only that, theories.

          Anyone who practices finger-tapping will become a faster finger-tapper. Probably the results of the study only show that younger people are more likely to have played computer games. Practicing motor coordination improves response times.

          In my grandparent post I meant to say that "should" indicates a theory, not that nothing is known with more sureness than theory.

      There is No "one" point where the body stops working. Different systems age at different rates:

      - the reproductive system peaks somewhere around age 16 or 17 (lowest risk of birth defects)
      - the *desire* for sex peaks just prior to menopause for women (circa age 35) and apparently never ends for men ;-)
      - flexibility (ala gymanasts and skaters) peaks at 15 and ends around 25
      - reaction time peaks at 30
      - and now it's revealed that the human brain peaks just prior to 40 - after which the neurons' tendrils start falling apart (like an old rubber hose).

          First, I have to say, take the following with a grain of salt, since it's anecdotal:

          Most of the research on the 'racetam family of bioactives has been done in Russia, and because of this there are both mistrusts and language barriers to overcome, but in doing so I discovered some pretty massively interesting studies all about specifically myelin sheath issues. So, since these substances are freely available in the US without any kind of prescription (unlike Russia, interestingly), I purchased a few and fed them to my mother, who is in the last couple of stages of post polio syndrome, which among other things (to put it in a nutshell) severely inhibits myelin effectiveness in nerve sheath maintenance. When she started the regimen a year ago, she couldn't walk at all and had great difficulty grasping things with her left hand, and was also in tremdous pain.

          Just a week ago she and I walked about six blocks to a restaurant, and then back. She can grasp things in her left hand fairly well at this point, and is in very little pain.

          I don't know myelin "helping" nootropics are the holy grail of neurological disorders, but they appear to have helped at least one person tremendously.

          The fuck it is. It's bad reporting. The actual research is all about how motor response speed correlates extremely well with myelin degradation, and discusses how this backs up the idea that myelin degradation is important in the aging of the brain and the resulting reduced physical ability. Even the press release, entitled "Physical decline caused by slow decay of brain's myelin" only mentions the 39-year figure once, and only in the context of this particular sample group, two-thirds of the way down the web page. 39 is the age at which finger tapping speed and myelin integrity both peak and begin to decline. At no point do the researchers claim that this has anything to do with cognative performance, let alone extrapolate it to say that there's some magic age at which mental function begins to decline.

    From what I have read, this only appears to apply to the speed of thought, which impacts on our reaction speeds. This would chime with most people's experience of ageing.

    What I would be interesting in is whether it actually has a knock-on effect on the quality of cognitive ability. Does thinking faster equal thinking better?

    Also, I wonder if the increase in experience is enough to overcome the reduction in reaction speeds. For example a 17 year old may have a great reaction speed, but that doesn't automatically make them a better driver than a 40 year-old with 20+ years of predicting the motion of objects travelling at speed and planning accordingly.

    Brains Work Best At Age of 39

    I was in a bad car wreck at age 24, dropped ten points on my IQ. Lucky for me it was 142 before the wreck.

    It seems to have gotten progressively better since then, until a few years ago when it kind of reached a plateau; I don't think I'm as creative as I was a few years ago.

    When the sheath deteriorates, signals passing along the neurons in the brain slow down. This means reaction times in the body are slower too.

    That doesn't mean you're not as smart, it means your reflexes are slower. You're born as intelligent as you'll ever be; your capacity to learn is at its maximum. However, you are also as ignorant as you'll ever be, as you know absolutely nothing whatever.

When I think about something, irrelevant associations will pop in with much greater frequency, distracting me from "pure" concentration. Which makes me wonder if it's simply a natural consequence of life: more and more detail is stored away in my head. A younger person with a relatively "empty" head isn't as distracted by all the useless dreck and is able to form thoughts more cleanly.

    Even as I type this post, my lifetime of experience keep popping in with tangentially relevant information, not to mention songs triggered by phrases, movie quotes and other useless crapola. :D

    I've actually wondered if there are mental exercises such as meditation that might help to quiet all the noise.

      Vipassana or insight meditation is what you are looking for.

      I observe the same effect - I'm 38 - however I think it's simply exaustion from the lack of sleep and brain-downtime. The older you grow the more structured your every day life becomes and the more compact and effective your calendar becomes and the less you notice exaustion, simply because you have

      I know the kind of noise you're talking about, and I would recommend a different approach - rather than learning a technique to "block it out", instead learn techniques for effective brain "multi-tasking". You can keep a very strong focus on the topic at hand, as well as let the useless dreck wander through without interrupting you (but if something useful floats by, you can grab it and run with it).

      My recommendation for this would be to overly excite your brain for a bit with LOTS of useless extra informa

  • Sure, not even 4 weeks after I turn 39 they come out with this.

    Now I have scientific proof that it's all down-hill from here. :-P

    Historically, their most significant work is done before age 30.

      That's probably true for most people. After 30, most folks have settled into raising a family, etc. and that takes time away from work.

    It might be slower, but I hope the experiences accumulated through the last 39 years still payoff after that.

    It's like a higher latency link doesn't mean worse if bandwidth is high enough.

    Another analogy is that the CPU clock rate is not the answer of everything. The cache, architecture and everything also play a role.

    It's more like you should shift from NetBurst to something else at around 39.

    If this research is replicated and is true this is actually a HUGE finding. Previous research showed that our brains started slowing down after age 25 or so. 39 is a big difference. They also said that myelination increases until age 39. That's the really important finding (before we said that we were done at age 25 at the latest). Trust me, this sort of research is very similar to what I do (white matter and brain volumetrics in aging populations). This, if true, is a very important finding.
