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.

    Many people can't tell the difference between the hyphen (-), the en-dash (–), and the em-dash (—). They may look similar but they can all help ensure that your writing looks professional and is easy to read. As an overview:

    • Hyphens improve clarity: there is a big difference between "a man-eating shark" and "a man eating shark".
    • En-dashes and em-dashes share a lot of the same functionality – including allowing for explanations and examples to be shared, and separating clauses – however, they are not interchangeable and their use is often down to personal preference.

    Let's explore what these three different dashes do and how they could improve your writing.

    My lifelong learning journey: Why learning English never stops

    By
    Reading time: 4 minutes

    Why did I want to learn English? When I was 9 years old, I became sick of French at home and I decided to go for the "opposite": English. I fell in love with it the moment I started learning. Though I could not see the point in many activities we were asked to do, such as turning affirmative sentences into negative and questions, or transforming conditional statements, I was good at it and hoped that at some point, I would find the meaningfulness of those exercises.

    Overcoming challenges in English language learning

    I kept on learning English, but the benefits were nowhere to be seen. In my school, classes are monolingual and teachers and students all share the same mother tongue. However, translanguaging was not an option. I even remember being told to forget Spanish, my mother tongue, which was as ridiculous and impossible as asking me to forget I have two legs. Before I finished secondary school, I knew I wanted to take up a career that had English at its core.

    From student to teacher: Finding purpose in teaching English

    I started the translators programme, but soon I saw that it was teaching that I loved. I changed to that and I have never stopped teaching or learning. All the pieces fell into place as I was asked to use English meaningfully, as I started focusing on meaning rather than on grammar. And I made this big learning insight one of the principles and main pillars of teaching. Some heads of school wondered why I would not follow the coursebook. My answer, since then, has been: I teach students, not a book or a syllabus. Because I was focusing on using English with a purpose – using it meaningfully – the results were excellent, and my students were using the language. And they passed the tests they needed to take.

    Teaching English with meaning: Moving beyond the coursebook

    I used coursebooks, as every other teacher did, but continued to make changes that I thought would be beneficial to my learners. As I taught Didactics at university in the Teacher Education Programme, I was invited by some publishing houses to give feedback on new coursebooks. As I was told, the feedback proved to be useful, and I was asked to start modifying international coursebooks to fit the local context and design booklets to provide what was missing in these adaptations, until I was finally invited to write a series for Argentina.

    In all the series I’ve written, my first comment has always been: “This is the result of my experience in several different classrooms, with different students from various backgrounds. This is a series by a teacher and for teachers and their learners. The focus is not on teaching, but on what is necessary for students to learn."

    Flexibility has always been at the core of these series and my teaching as well. Sometimes students need more work on something, and in the Teacher’s book I included several suggestions for further activities, which I called “building confidence activities”.

    Flexible teaching strategies and confidence-building activities

    As I got involved with the GSE, I saw how it can help students learn much better, and how it can support teachers as they help learners. How so? Because it starts with a focus on using English rather than on learning about it, that is, learning about its grammar. I’ve shared my views on it with every colleague I can and it has been the topic of several presentations and national and international conferences. It’s a fantastic resource for both teachers and learners, but also for the wider educational community. When the scales were finally published, I remember thinking, “Oh my, I was born in the wrong century!”

    I am still teaching English – working at schools as a consultant, designing professional development projects and implementing them, and yes, actually working in classrooms, teaching learners. After many years of teaching English, and still loving it, the best advice I can give is this:

    Advice for English teachers

    Teachers, we’re blessed in that we do what we love, and despite its challenges and hard times, teaching is absolutely rewarding. Nothing can compare to the expression on a student’s face when they've "got it".

    Remember to focus on meaning, help learners become aware of what they already know and set a clear learning path that will keep you and them motivated. The GSE is the best resource and companion for this.
