Being bilingual can help keep your brain in good condition

Learning and understanding a new language is one of the most challenging things that your brain can do. But as well as the advantage of acquiring another language, it appears that the effort of giving your brain a good workout today by being bilingual could keep it in better condition in later life.

Research led by Dr. Daniela Perani, a professor of psychology at in Milan, found that people who speak two or more languages seem to weather the ravages of Alzheimer’s disease better compared to people who have only mastered one language. Alzheimer’s is a progressive mental deterioration that can begin in middle or old age due to generalized brain degeneration.

The study involved 85 people with Alzheimer’s – half of whom spoke both German and Italian and half who spoke only one language. The researchers found that bilingual patients had greater connectivity in key brain areas. This was especially in the part of the brain that governs “executive control” – a set of necessary behavioral cognitive processes that include problem-solving, working memory, reasoning and attentional control. The study also noted that the bilingual Alzheimer’s patients showed less severe symptoms of the disease.

The study concluded: “Our findings suggest that the effects of speaking two languages are more powerful than both age and education in providing a protection against cognitive decline.”

Bilingualism and the brain

Although Alzheimer’s disease is currently incurable, the study supports a popular theory that people who have higher levels of education function longer with little manifestation of the illness. Part of the reason why bilingual brains may be better at resisting Alzheimer’s could be due to a lifetime of switching between languages daily.

Learning and speaking more than one language changes how the brain carries out tasks that require focus and concentration on a certain piece of information without being distracted. It can also increase the density of white matter (connections) in the brain, meaning that there are more connections between brain parts, thus making this part of the brain more resistant to degeneration.

This is supported by a study conducted by a team led by Professor Ana Inés Ansaldo at the , which suggests that bilingual people have more robust and more efficient brains compared to those who only speak one language. This is one of the reasons why a bilingual brain can be a buffer against aging and dementia.

They recruited elderly people, half of whom spoke only one language and the other half who had learned a second language between the ages of 11 and 18. All performed equally well on a task that involved focusing on an object's color while ignoring its position, but brain scans revealed a big difference in how they processed the task.

“While bilinguals were recruiting very specific brain areas and a small number of areas to perform the task, monolinguals were recruiting a much larger number of areas that were consuming much more resources. And the networks they were using were very, very complex,” says Professor Ansaldo. “That led us to think that the bilingual brain was more efficient in terms of the amount of resources that bilingual people require to do complex tasks as opposed to the monolingual brain.”

The study concludes that bilingualism shapes the brain in a different way or how people approach complex tasks. It could be because bilinguals must inhibit the language they are not using to focus on the one that they are using.

    5 ways to improve English test results

    By Charles Hamilton

    As with all tests, adequate preparation is crucial. For many aspiring migrants needing to take an English test, it may have been several years since they took an official exam. Knowing how to prepare effectively and what to expect on the day are key when it comes to securing a successful outcome. Use these five exam preparation tips below to improve your English test results.

    1. Familiarise yourself with the type of test questions you will be asked and know what to expect on the day

    The official guides published by the testing bodies are an excellent source of information to help you fast-track your learning. They offer materials that replicate the real test questions as well as guidance and strategies for dealing with every task set. Taking a practice test in exam-like conditions helps to improve time management skills and set realistic expectations on your potential performance.

    As with all high-stakes tests, security arrangements at the test center are strict. Test takers need to prove their identity via a passport or similarly approved document, so it’s a good idea toarrive at least 30 minutes beforethe test time and have your documents to hand.

    2. Give yourself enough time by setting clear, measurable and achievable goals. This will help keep your motivation up and your end goal in sight

    Start with a detailed understanding of your current English proficiency. That makes it easier to focus on any weaker areas ahead of taking the test and plan how long you’ll need to study for to bring your skills up to the required level.

    3. Seek English instruction that works for you and matches your specific needs and learning goals

    Coursebooks are a good option if you have a little more time to study in the run-up to the test. A rigorous preparation course structure will take you through a series of normally class-based lessons designed to prepare you for the test. Sometimes, however, the best way to prepare for a test is to join a class and receive tuition face-to-face. There is a multitude of courses and they offer class-based or individual tuition, from intensive week-long courses to six-month programs to help brush up on your English skills.

    4. Choose quality materials that are at the right level for you – they should stretch you a bit to help you progress so you stay motivated

    Digital learning can be very useful, providing opportunities to study at a time that suits and giving lots of feedback opportunities. Many test-takers take advantage of the large amount of free preparation material that includes everything from print and digital course guides to practice tests. A huge amount of information is also posted on YouTube, including tutorials and advice covering the range of different tests on offer.

    5. Be persistent – keep practicing at every opportunity

    Make the most of those spare minutes to practice your skills. Every workday includes a little downtime so try to incorporate a few short 5 or 10 minute practice activities each day to keep building your knowledge.

    IELTS has long been the standardized test approved by the Australian government and the test of choice for visa applicants both for work and study. Since November 2014, in an effort to make it more convenient for applicants, the DIBP has approved a number of additional tests that can be used as proof of English language skills, including TOEFL iBT, Cambridge English Advanced (CAE) and the  (PTE Academic).
