Canadian researcher published earlier this year a study showing that people who regularly used two languages showed signs of dementia 4 years later than people who used only one language!

It looks like bilingual brains are more resistant to the effects of cognitive decline. Previous studies by the same researchers had established that bilingual people were better at paying attention and ignoring distractions. Ellen Bialystok, the lead researcher on these studies, believes that this is because bilingual people always have to decide which language to use and suppress the other. This would provide practice in focusing attention, sorting through conflicting information and ignoring distraction.

Bilingualism may delay dementia in the same way that mental activity is thought to, that is by contributing to building cognitive brain reserve. However, we don’t know yet whether the same effects would appear if you start learning a language at 50.

Brain Activity Reduces risk of Developing Neurodegenerative Diseases

A new study now confirms our beliefs: Train your brain on a regular basis and you should be able to considerably reduce risks to develop Alzheimer’s disease.

In Chicago, a major 5 year project that studied over 700 patients aged 80 and over has just come to an end and the medical team’s findings are unequivocal: an elderly person not practicing a brain activity is 2.6 times more likely to develop Alzheimer’s disease than a person with regular and stimulating brain activities such as reading, writing, listening to music or any other cultural activity.

The study also emphasizes the fact that these observations still apply when the activity is only taken up at an advanced age.

So it may never be too late to start training!

Adding years to your life depends on many things – good genes are a start, but certain lifestyle habits can have quite a significant impact. Living longer is one thing, and living a cognitively strong life can be quite another. Health and Medical magazines have long touted the benefits of certain healthy behaviors for body and mind, and this theme is being expressed in an ever more diverse set of publications. I wanted to share an article you from this month’s National Geographic Magazine. In the article “Complex Miracles of Health and Simple Ways to Enhance It”, they profiled three global hotspots of longevity and found living proof of lifestyle’s powerful effect. Check it out at www.nationalgeographic.com/healthyliving. Also discussed are tips for enhancing your own longevity profile including “Seven Basics for a Better Brain”. These include:

• Laugher has been shown to reduce at least four of the neuroendocrine hormones associated with stress response.
• Children who eat more meals with their families feel happier about their lives and prospects for the future
• Breath deeply for five minutes, twice a day
• Drinking more water helps your brain stay focused, think faster, and remember more
• A short, brisk walk helps clear stress hormones from your bloodstream
• Fish rich in omega-3, like salmon, can improve brain function and may help prevent Alzheimer’s disease
• Exercise sends oxygen to your brain – improving memory, reasoning skills and concentration

It’s all a reminder that we have the opportunity to lead long, healthy, active and cognitively strong lives.

More news suggesting music can help to sharpen the brain.

“Experience with music appears to help with many other things in life, potentially transferring to activities like reading or picking up nuances in tones of voices or hearing sounds in a noisy classroom better,” researcher Nina Kraus, a neuroscientist at Northwestern University”

We found this post that mentions Dr. Paul Nussbaum’s approach to brain health. Dr. Nussbaum does a great job of communicating the importance of a fit brain to the public

Dr. Nussbaum says that a healthy lifestyle characterized by socialization, physical activity, mental activity, spirituality, and nutrition leads to improved brain health. Individuals should reduce their caloric intake to 80% of what they intend to consume at each meal because overeating and obesity do not contribute to brain health.

Another study showing the impact of learning on our brains.

“These remarkable findings suggest stimulating the mind with activities such as reading books or completing crossword puzzles may help delay and/or prevent Alzheimer’s disease in senior citizens.”

Here is another study on the benefits of studying another language.

“If you have two languages in your brain, you need a way to keep them straight, otherwise you might say the wrong thing,” she said. It’s one of the things that often goes wrong with people suffering from dementia. They can no longer control their speech.The frontal lobes, which control planning and other high-level functions, are also used in language. Research has found exercising that part of the brain can help build up a “cognitive reserve,” which can stave off dementia.”

A good article over at US News and World Report on how cognitive decline is impacting people under 65.

“Several hundred thousand people–perhaps as many as 640,000–under the age of 65 who have dementia, the vicious thief of minds that steals memories, personality, relationships, language, and ultimately the ability to function as a human being”.
