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.

  • A Parent reading to his two children from a book with all three of them laying on the floor

    How can teachers encourage parents to get kids reading at home?

    By Donatella Fitzgerald MBE

    “Sharing a story with your child is one of the most incredible things you can do for them.” – .

    Research shows that getting kids reading at home can increase their reading ability at school – and improve their overall well-being. Parents and guardians can make a big difference. But how can teachers encourage parents to get their children to read more at home? We explore some strategies you can use.

    Tell parents about the benefits

    Reading can give children a break from technology-centered activities. It can help them to relax and unwind; reading a book can make children laugh and feel happier! Through hearing stories, children are also exposed to a rich and broad vocabulary.

    “It is important for teachers to establish contact with parents as much as possible and give very clear guidelines on the benefits of reading, and how they can create a reading routine and help their children read at home,” says Kasia Janitz-De La Rue, Product Development Director at app.

    So, encourage parents to find time for a reading routine. Just before bedtime is a great time, as .

    Give parents practical ideas for reading strategies

    Encourage parents to read with and not to their child. It doesn’t matter how long they set aside to read – just 10 minutes of quality reading time can make a big difference.

    Here are a few tips concrete reading tips for teachers to share with parents:

    • Ask children lots of questions while reading.
    • Use encouragement and praise to keep children engaged. Saying things like “what fantastic ideas” or “you thought so carefully about that, what might happen now?"will keep their minds working.
    • Use their past experiences to talk about what’s being read. Things like “have you learnt about…at school?” or “do you remember when we watched…and found out about…?” are good conversation starters.
    • Tune in and listen to children, and be curious about their interests. “I didn’t know you knew so much about…” or “I love reading stories about…with you,” are good phrases to keep in mind.

    It’s also a great idea to share online resources with parents. You can also suggest that parents look up read-aloud YouTube videos featuring authors, teachers or librarians reading their favorite stories. This way, children can watch and listen as often as they like.

    Recommend graded readers

    Graded readers are books that use language in line with a child‘s learning level. They can help children build confidence, and help slowly expose them to authentic reading levels.

    Encourage parents to identify what genre their child is interested in and show them the readers available. Each time parents see their children move up a level, they’re sure to see their children’s love for reading grow.

    Suggest before, during, and after reading activities

    Before reading

    Parents can take turns with their children to predict what the story is about – or what will happen next. Here is an activity teachers may suggest they try:

    “Start with the cover of the book and the blurb on the back cover. Reveal the cover slowly to ask the child what they can see. Ask them to guess what is on the cover. Once they have seen the cover, ask them questions about the images on the cover – who, what, why, where and how?”

    While reading

    Remind parents to focus on their children’s reading comprehension by using strategies like prediction, questioning, clarifying, and summarising. Teachers can ask parents to:

    • check ideas and understanding as the child reads: ‘So, you think that….’ ‘Did you expect…to happen?’ ‘Why do you think that happened?’
    • use the pictures in the book to help with comprehension
    • describe what is happening and talk about the characters.

    After reading

    Don’t forget: parents can continue to explore the book’s topic once reading time is done! A few ideas to share with parents include:

    • organising a puppet show for family members and siblings after making puppets of the characters in the book
    • having children draw a picture of their favorite character or their favorite page in the story
    • encouraging children to express their opinion on the book.
