Exercise is beneficial for the brain

By Sandrine Belier Ph.D., posted on August 5, 2011 at 9:54 am

Physical exercise and brain health We often hear advice telling us that doing some kind of physical activity is good to develop muscle, lose weight, or generally to stay healthy. But what if doing exercise was also good for mental abilities?
Last February, we already said that being physically active is very important for our cognitive health. Recently, two teams of scientists confirmed our article.

Their studies, published in the Archives of Internal Medicine, show that the practice of physical activities has beneficial effects on the brain.
In the first study, The Canadian team led by Professor Laura Middleton examines the link between energy expenditure and mental faculties. A study was conducted with 197 persons aged 74 for two to five years. The results confirm that active people have 90% lower risk of showing an important cognitive decline. As physical activity was interpreted broadly, walking around the house or even doing household chores may protect us from brain decline observed in dementia!

The French team led by Marie-Noel Vercambre reaches the same conclusion; the study was conducted on a large panel of women with vascular disease or risk of developing heart disease. Researchers followed them for as long as 5 years; physical activity was measured every two years and three or more mental and memory tests were given. The results showed that the more active women were, the less risk they had to develop cognitive trouble. They also added that 30 minutes of daily walking may decrease the risk of developing cognitive impairment.

Do you still hesitate to be physically active?

Internet may Influence your Memory Skills

By Sandrine Belier Ph.D., posted on at 2:38 am

Internet is well known to be a quick and easy way to access to knowledge. But did you know that using it could affect the way we store information?

The team of Betsy Sparrow, assistant professor in psychology at Columbia, analysed the impact of the huge accessibility of data through Internet on memory skills. One of the experiments consisted in typing one sentence and test its memorisation. The results showed that people were more likely to forget what they write if they knew that the data was saved. Moreover, easy access to data may also affect what we precisely remember. Indeed, in the experiment, subjects memorize better the way to find the information than its exact nature.

This study is one of the first that explores the effect of Internet on memory but it seems that the brain would adapt to new technologies and take profit of it to memorize only the more valuable information.

March is National Nutrition Month®

By Sandrine Belier Ph.D., posted on March 25, 2011 at 3:34 am

National Nutrition Month® is a nutrition education and information campaign created annually in March by the American Dietetic Association. The campaign focuses attention on the importance of making informed food choices and developing sound eating and physical activity habits. This year’s theme is “Eat Right with Color”.

National Nutrition Week was first observed in 1973 as a week-long event, to later become a month-long campaign from 1980 on. The website offers a great choice of material on nutrition education to improve one’s nutritional habits. It includes such tips as how to generally eat healthier and smarter, make your children and grandchildren enjoy fruit and vegetables, eat adequately to keep a normal and healthy weight, adapt your food habits to your age, and a lot of further interesting information.

The website also gives information on registered dietitians and in how far consulting such a nutrition expert could be benefitting for you and your health. A registered dietitian can put you on the path to lowering weight, eating healthfully and reducing your risk of chronic disease by giving you food and nutrition information based on fact and providing you with a personalized nutrition plan adapted to your age.

More information on the campaign can be found on the American Dietetic Association website which also offers scientifically based food and nutrition information here…

Treating Depression and Anxiety with Video Games

By Laura Fay, posted on March 10, 2011 at 6:02 am

A study from East Carolina University has recently shown the effectiveness of casual video games to treat depression and anxiety. The researchers worked with 60 subjects suffering from depression, half the group representing control subjects. The team recorded an average decrease of 57% of depression symptoms, found that the subjects had become less anxious, and noticed that their mood had also improved. Both short-term effects (after 30 minutes of game play) and long-term efects could be recorded (after one month).

Casual video games can this be considered as an option in the treatment of depression and anxiety, either complementary or as a replacement to currently existing therapies.

Taking it further, for several years Scientific Brain Training, the company who has designed and developed the HAPPYneuron brain fitness program, has been working  on Scientific Brain Training PRO website, a platform for professionals for the effective delivery and management of cognitive remediation and rehabilitation programs in a patient centric manner. Scientific Brain Training PRO facilitates the effective treatment of a variety of neurotrauma, neurodegenerative and neuropsychiatric conditions through standard and specialized programs consisting of fun and interactive games specially designed for targeted stimulation of key cognitive functions.

Changing Your (Cognitive) Fitness Habits

By Dr. Michel Noir, posted on February 25, 2011 at 4:26 am

So we’ve read it in many studies: Physical exercise is important and contributes to a healthy life style. It has also been shown to be essential for cognitive health, helping us not only to remain physically fit but also to maintain mental sharpness.

Today, however, researchers find that it is not enough to inform people. This solely informative approach is not sufficient and motivating enough to get people to change their life styles accordingly and become more active.

In order to change behaviors it is now essential to also offer strategies, as the researchers from MU Sinclair School of Nursing found.

When it comes to cognitive fitness, the HAPPYneuron program can be considered as a brain training strategy in itself. It provides you with a coach on which you can rely to prepare your training sessions, depending on what type of training you have asked for or even the length you have chosen. You also have the opportunity to set training reminders for yourself via email in order to not forget your sessions.

There are many other ways to improve and keep up your cognitive fitness habits.

In addition to our training reminders, you can also:

  • plan your week ahead and write “training slots” in your diary,
  • start by setting yourself short sessions and stick with the strict minimum advised (2-3 sessions a week, at least 20 minutes each) if you think you don’t have the time, then slowly increasing session duration etc…
  • get friends and family involved to make your HAPPYneuron something to share with people, a conversation topic
  • when feeling less motivated, choose those games you like best rather than do a session chosen by the coach

On top of HAPPYneuron, you can also start with little training exercises such as:

  • memorizing phone numbers rather than writing them down
  • trying to do your shopping without a list
  • asking yourself random questions such as “What was I wearing last Thursday?” or “What did we have for dinner on Monday night?”

Can you think of any more strategies to train your brain?

Information Retrieval Improves Learning

By Sandrine Belier Ph.D., posted on February 10, 2011 at 6:08 am

According to recent results published in the journal Science, using memory retrieval as a learning technique may be an excellent method to improve meaningful science learning.

Researchers from Purdue University asked 200 students to study science texts, one group using information retrieval practice and the second elaborative studying with concept maps, after which several retention tests were conducted.

The results showed that those students who had used retrieval pratice were able to learn more effectively than those who had used elaborative studying. Memory retrieval seemed to be particularly helpful for meaningful conceptual learning about science as the tests showed that it enabled the students to understand concepts and implicit facts that had not been stated in the text they had learned.

A Link Between Pesticides And Dementia

By Dr. Bernard Croisile, posted on December 16, 2010 at 6:08 am

PesticidesThe results of a new study on 614 French vineyard workers in their 40s and 50s shows that there may be a link between a long-term exposure to pesticides and dementia.

The study participants, who had worked in their industry for at least 20 years, were divided into different groups: those who had never been exposed, directly exposed or indirectly exposed to pesticides throughout their career. Their intellectual skills were monitored over a period of 6 years with several different tests involving memory and recall, language retrieval, verbal skills and reaction time measurements. Capacities were assessed twice.

According to the results, workers exposed directly to pesticides were most likely to do worse on the second test. They were also the most likely group to achieve lower scores on both tests as well as in the Mini Mental State Examination (MMSE) which is used to test cognitive functioning and may indicate a person at risk of dementia. The researchers qualified this brain decline in MMSE “is particularly striking in view of the short duration of follow up and the relatively young age of the participants”.

When Retirement Leads to Memory Decline

By Sandrine Belier Ph.D., posted on December 10, 2010 at 11:02 am

retirementIf you are now looking at the picture and thinking “This is how I want my retirement to look like”, think again! A recent paper with the title “Mental Retirement” is currently suggesting that early retirement may lead to quicker memory decline.

According to Laura L. Carstensen from Stanford University, “[The study] suggests that work actually provides an important component of the environment that keeps people functioning optimally.” The analysis of the data which was collected for the study suggested people may have to engage in stimulating activities to preserve memory and reasoning skills after their retirement.

The study which was published by economists Susann Rohwedder and Robert J. Willis in The Journal of Economic Perspectives supports the “use it or lose it” theory as well as the idea that cognitively stimulating activities may delay cognitive aging. It was started about 20 years ago by the National Institute on Aging on a sample of 22,000 Americans who were submitted to memory tests every two years. Several European then started their own national studies and are being followed by countries such as Japan and Corea, using similar proceedings in order to obtain comparable data. It was found that “the longer people in a country keep working, the better, as a group, they do on the tests when they are in their early 60s”.
