This recent report??is an old story, but I never tire of reading about it. ??I am assuming that multilingual people are even more protected from Alzheimer's. No why is it that I seem to forgetting things, and misplacing things more and more?
The paper by Canadian researchers, published Thursday, suggests bilingual people have higher cognitive reserves as they get older. Higher cognitive reserve is associated with a lower risk of Alzheimer's and other memory-destroying dementias.
It's not exactly clear why. But one theory is that managing two different languages boosts brain regions that are critical for general attention and cognitive control.
"We know that if you know two languages, and that there are two languages you could be speaking at any time, then both of those languages are always active – they're always kind of 'available' in your mind," she said.
"That means that every time you want to say something or understand something or write something, there's potential interference from the other language."
When that happens, the brain's executive-control system kicks in to man-age the conflict between languages.
The executive-control system is the basis for our ability to multi-task and to stay focused on what's relevant and avoid distraction.
In bilinguals, that brain network gets "massive practice," said Bialystok, a Distinguished Research Professor at York.

Pienso que esto es verdad, una gran verdad ya que si el cerebro se mantiene activo hablando dos idiomas a la vez, sus neuronas no moriran y se volver?? ??gil y no aletargado de manera que esas enfermedades que tienen que ver con la memoria ya no tienen cabida en un cerebro que est?? en constante actividad.
That is really very interesting artical I have recieved in this months, The truth to be told this subject was very important for me. Thank you very much Steve and have great one.
Hi, Steve, "why is it that I seem to forgetting things, and misplacing things more and more?" The other day I complained to my doctor about the same thing, he applied a memory test on me and said that the only thing I needed was an agenda, because I had too many things in my head. :OI guess you have too many language in yours… ahahahahCheers, Ana
You are probably right Ana, but I am not stopping. When you have some time again, I would like to chat with you in Portuguese in order not to forget what you helped me learn, and to further stave off Alzheimer, (now where did I put my mp3 players again?)
