Can Computerized Brain Training Prevent Dementia? (newyorker.com)

"Researchers believe they have found a link between speed-of-processing training and a reduction in cognitive decline among the elderly," reports the New Yorker. An anonymous Slashdot reader quotes an article about how this new long-term study actually contradicts much of the previous science. In October of 2014 a group of more than seventy academics published what they called a consensus statement, asserting that playing brain games had been shown to improve little more than the ability to play brain games... no brain game, nor any drug, dietary supplement, or lifestyle intervention, had ever been shown in a large, randomized trial to prevent dementia...until today, when surprising new results were announced at the Alzheimer's Association annual meeting, in Toronto.
Nearly 3,000 participants with an average age of 73.6 participated in the study, with some receiving "speed of processing" training -- and some later receiving four hours of additional training. "The researchers calculated those who completed at least some of these booster sessions were 48% less likely to be diagnosed with dementia after ten years than their peers in the control group." Signatories of the 2014 consensus statement panning brain games are now calling these new results "remarkable" and "spectacular".

    It's one study. Wait for independent duplication before calling it remarkable. It could still be proven to be as much of a hoax as vaccines causing autism, global warming, or evolution. Exercise caution in believing a single study.

      What is fascinating is that this might now extend the "All of your problems are your own fault" crowds finger pointing to the final frontier - dementia.

      It even seems like a plausible premise, that using the mind keeps it healthy, but it could very well mimic a slow cognitive decline. If a person disengages from intellectual activity, it might just be that they were already naturally declining anyhow.

      anyhow, if it is true, I shouldn't have much problem - since retirement I've taken on many new mental endeavors. Tho' some think I am already demented.

    I watched this horrible disease reduce two of the most powerful men in my life (direct relatives) to living corpses that could not even remember their own names. Truly, I hope no one ever has to face the horror of this disease either in themselves or someone they know.

    What is even more saddening is the amount of ignorance that surrounds this disease. I had a friend whom, upon finding out that I had relatives who had Alzheimer's, say he was glad that he had no family history of the illness, because he would never have to worry about this terrible affliction. It was quite a shock to him when I advised him that people with no family history of Alzheimer's make up a good portion of new Alzheimer's diagnosis every year. He flat out refused to believe me, going as far to assert that he KNEW that ONLY people with a family history of the disease capable of getting it. I was astounded at the ignorance.
