The multi-tasking is bad for the brain

do several things at once is not is good for the brain and does not make us more efficient. The "multi-tasking" can make stressed, angry and mentally fatigued and cause learning problems in children, and ironically makes us even less effective in the things we do.

The research has discovered a Massachusetts Institute of Technology, published in the Journal of Experimental Psychology. "Doing more things at once requires more energy from the brain that does not make them one after the other," said Earl Miller, a researcher at the head of the study that scanned the brains of volunteers to see which areas are activated when you perform multiple actions.

"Our brain really is focused on one action at a time. The other simply distract us and slows us down, "said Miller, who do not recommend multi-tasking unless it is absolutely necessary.

"Even people not capable of being convinced they can. Our brain is not made to think in this way. If you must combine more work frantically, "Miller concluded," to avoid doing so in the afternoon, learn a bit 'of meditation and practice to combine a few simple steps at a time. "

mental exercises protect the memory from dementia

Reading, writing and playing cards are not only pleasant pastimes under the umbrella. This is, in fact, true mental exercises, able to keep your brain trained and even delay the rapid decline in memory in case of dementia. At least according to a study to be published tomorrow on "Neurology" by the team of Charles B. Hall of the Albert Einstein College of Medicine in the Bronx (NY). The research involved 488 people aged 75 to 85 years, who suffered from dementia at the start. Researchers have observed and monitored them for an average of 5 years and found 101 in the meantime we are suffering from dementia. But scientists have also discovered that the most passionate reading, writing, crosswords, puzzles, chess or cards, the ones who spent more time each day engaged in these activities, they were as protected from the effect of dementia-eating memories. In practice, though attacked by the disease to their point of rapid mental decline came after more than a year on average than the least active. "And the effect of these mental exercises in old age seems independent of culture. In short - Hall concludes - these activities can help maintain brain vitality. Although further studies are needed to determine if they are also able to prevent or delay the onset of dementia. "
