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.

    Exploring the four Cs: Using future skills to unlock young learners’ potential

    What do we mean by future skills?

    The skills students will need in their future studies and careers are dramatically different from those required previously. Times are changing rapidly and educational institutions and teachers have a critical role to play in developing those skills in our young learners so that they are able to fulfill their potential and have bright futures ahead of them.

    These skills are referred to as future skills. There is no common consensus on how to define these skills but, broadly speaking, they can be grouped into four categories:

    1. Ways of thinking

    Skills in this category include critical thinking, creativity, innovation, problem solving, metacognition and learning skills.

    2. Ways of working

    Here, we’re talking about the skills of communication and collaboration.

    3. Tools for working

    Information literacy is an important 21st-century skill, as well as ICT literacy and citizenship, both global and local.

    4. Life skills

    The final category covers life and career skills, and is all about personal and social responsibility.

    One way you can encourage young learners to build these skills is through STEAM subjects (that’s science, technology, engineering, arts and math), which will equip them with functional skills such as organizing, planning, cognitive flexibility and self-regulation.

    The four Cs

    The four Cs refer to four important skills for young learners to master: communication, collaboration, critical thinking and creativity. These are essential, not just in an educational context, but in everyday life.

    Falling into the first two categories of future skills (ways of thinking and ways of working), these can help children build confidence and self-esteem. They also encourage healthy emotional development.

    So let’s take a closer look at the theory behind them.

    1. Communication

    We usually think of communication as speaking and listening, but it’s actually much broader than that. Communication encapsulates telling stories, reading, sharing ideas and experiences, body language, facial expression, eye contact and tone. Children learn to decipher the world around them by learning and practicing these skills.

    Strong communication skills, developed early, are directly related to their literacy success. These skills allow children to articulate their thoughts and ideas effectively, and listen to decode meaning. Students then begin to use communication for a range of purposes, and communicate effectively in diverse environments. Furthermore, developing strong patterns of verbal and non-verbal communication also fosters self-esteem and social skills.

    2. Collaboration

    Collaboration is how young children begin to build friendships with others. At first, young children will watch what others do and say, before moving on to playing together. As they get older, they become aware of other children’s feelings and ideas. Friendships become motivating and they learn how to make compromises and respect each other’s perspectives and skills.

    Collaboration is enhanced through group work and project-based activities, sharing time with peers. Children thrive when they feel valued by the people around them, not just adults but their peers too.
