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 spooky ideas for your primary classes this Halloween

    By Joanna Wiseman

    It’s almost Halloween, and the ghosts and vampires will soon be coming out to play. Did you know that although we often associate Halloween with pumpkin carving and eating candy, the festival has much older origins?

    is an ancient Gaelic festival that celebrates the end of the harvest and the start of winter. This is why people often associate the colors of orange and black with Halloween: orange is the color many leaves turn in autumn and black is the color of the darker winter months.

    People used to believe that spirits walked the Earth on the night of Samhain. The tradition of dressing up as ghosts and demons started as a way to hide from the spirits who walked the streets. Similarly, people used to leave treats outside their houses for the spirits and from this came the tradition of trick-or-treating.

    So to help get your younger students in the Halloween spirit, here are five spooky ideas to try in your primary classes.

    1. ‘Pumpkin’ oranges

    Pumpkin carving is fun - but it’s also messy and pumpkins can be really heavy. Instead, bring in an orange for each student and give them a black marker pen. Get them to draw a scary face on their orange and then write a short text describing it.

    My pumpkin orange, Ghoulie, has two big eyes. He’s got a small nose and a big mouth, with lots of teeth. This Halloween, he’s going to sit outside my house. He’s going to scare people but he doesn’t scare me. I think he’s very funny.

    2. Bat fishing

    This is a great way to practice questions and review language with your younger students. Have your students cut out bat shapes on card and tell them to write a question on the back of each one. They can write personal information questions, such as ‘What do you eat for breakfast?’ or questions related to topics you’re studying at the moment, like ‘How do you spell dinosaur?’

    Attach a paper clip to each bat and put them on the floor, with the questions face down. Then attach a magnet to a piece of string.

    Divide the class into teams and have students take turns to fish a bat from the floor. When they catch a bat using the magnet, a student from another team asks them the question written on the bat. If the team can answer correctly, they keep the bat. If they don’t answer correctly, the bat goes back on the floor.

    When all the bats have been fished, the team with the most wins.

    3. Haunted house dictation

    This is a good activity to review prepositions of place and house vocabulary. Before you start, elicit some scary things from the students, such as ghost, spider, witch, zombie. If these words are new for your students, draw a picture dictionary on the board for them to refer to in the next stage.

    Next, give students an outline of a house with the rooms labeled, but without any furniture. Then dictate a sentence to the students and have them draw what you say on their individual houses. For example, ‘In the kitchen, there’s a big cupboard. In the cupboard, there’s a witch.’ Or, ‘In the living room, there’s an old sofa. A zombie is sitting on the sofa.’

    You can then divide the class into pairs or small groups and have them take turns dictating sentences to each other. When they finish, they can compare their pictures and then write a short story about their haunted houses.

    4. Trick-or-treat board game

    Draw a 7x5 grid on card and add Start and Finish squares. Number the other squares so the students know what direction to move in. Then, on some of the squares write Trick and on some of the other squares write Treat. Finally, prepare a set of ‘trick’ and ‘treat’ cards for each group. (There are some ideas for tricks and treats below).

    Before students play, teach them some phrases to use while playing the game. For example:

    • Whose turn is it?
    • It’s my turn.
    • Roll the dice.
    • Who’s winning?

    Then divide the class into groups of four and give each group a board, a set of ‘trick-or-treat’ cards, a dice and a counter. Have them take turns to roll the dice and move. If they land on a Trickor Treat square, they have to take a card and do what it says. Then they put the card at the bottom of the pile.The winner is the first person to reach the Finish square.

    Ideas for ‘trick’ cards

    • Go back 3 squares
    • Miss a turn
    • Go back to the start
    • Count down from 10 to 1 in English
    • Say the alphabet backwards (Z, Y, X…)
    • Laugh like a witch
    • Pretend to be a ghost

    Ideas for ‘treat’ cards

    • Go forward two spaces
    • Roll again
    • Go forward five spaces
    • Choose someone to miss a turn

    5. Spooky stories

    Are your students bored of celebrating Halloween every year? Mix things up with stories or readers. Allowing their imagination to run wild. There are lots of you can use or get inspiration from, creating your own. If you want your pupils more involved you could also have them make or take part in your very own 'create your own adventure' spooky story.

    After reading the story, have your students create comic strips of different parts of the book and display them around the classroom. If your students prefer theatrics, get them to act out or sing parts of the story.
