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.

    If you are a student or one considering a gap year, the option of foreign exchange programs may have crossed your mind or been mentioned to you. More and more young people are taking advantage of exchange programs and reaping the transformative benefits that come with it.

    Let's have a look at some of the reasons why taking part in an exchange program can be a life-changing experience and how it can help you more than you think.

    What is a foreign exchange program?

    A foreign exchange program is an educational initiative where students have the opportunity to study abroad and immerse themselves in a different culture for a specified period, typically ranging from a few weeks to an entire academic year. These programs facilitate cultural exchange by allowing students to attend foreign schools or universities, live with host families or in dormitories, and engage in activities that foster intercultural understanding and personal growth.

    The primary aim of a foreign exchange program is to provide students with a global perspective, enhance their language skills, and expose them to different educational systems and cultural practices. By stepping out of their comfort zones, students can develop independence, adaptability and a deeper appreciation for diversity.

    What are the benefits of a foreign exchange program?

    1. Cultural immersion and global perspective

    Embracing diversity

    One of the most immediate benefits of an exchange program is the opportunity to immerse yourself in a different culture. Experiencing new customs, traditions and ways of life firsthand fosters a deeper understanding and appreciation of global diversity. This cultural immersion helps break down stereotypes and broadens your worldview, making you more open-minded and adaptable.

    Develop cultural understanding

    Living in a foreign country teaches you how to navigate and respect different cultural norms and practices. This cultural competence is increasingly valued in our interconnected world, enhancing your ability to work effectively in diverse environments and making you a more attractive candidate in the global job market.

    2. Language proficiency

    Enhanced language skills

    For language learners, an exchange program is an opportunity to achieve fluency. Experiencing a language firsthand is one of the best ways to learn a new language. Being surrounded by fluent speakers provides constant practice and exposure, accelerating your language acquisition in ways that classroom learning alone cannot match. You'll develop better pronunciation, expand your vocabulary and gain confidence in your speaking abilities.

    Real-world communication

    Using a new language in everyday situations—whether it's ordering food, asking for directions, or making new friends—helps solidify your language skills in a practical context. This real-world communication practice is invaluable, ensuring that your language proficiency extends beyond textbooks and exams to actual, meaningful interactions.

    3. Academic and professional growth

    Academic enrichment

    Exchange programs often provide access to unique academic resources and teaching methods that differ from those in your home country. Exposure to new perspectives and approaches can deepen your understanding of your field of study and inspire new areas of interest. Additionally, studying abroad can enhance your academic credentials, making your CV stand out to future employers or academic institutions.

    Career opportunities

    Experience abroad signals to employers that you possess qualities like independence, adaptability and cross-cultural communication skills. These attributes are highly sought after in today’s job market. Moreover, the networking opportunities during your exchange can open doors to international internships, job placements and collaborations that might not have been available otherwise.

    4. Personal development

    Building independence and resilience

    Living away from home in a completely new environment challenges you to become more self-reliant and adaptable. You'll develop problem-solving skills, resilience and the ability to thrive outside of your comfort zone. These experiences build character and prepare you for future challenges, both personally and professionally.

    Forming lifelong connections

    The friendships and connections you make during your exchange program can last a lifetime. You'll meet people from various backgrounds, creating a global network of peers and mentors. These relationships can provide support, inspiration and opportunities long after your exchange program ends.

    Successfully navigating life in a foreign country, mastering a new language, and achieving academic success abroad can significantly boost your confidence. This newfound self-assurance can positively impact all areas of your life, giving you the courage to pursue further opportunities and take on new challenges.

    5. Engaging with the local community

    Volunteer and community projects

    Many exchange programs encourage participants to engage with their host communities through volunteer work or community projects. This engagement allows you to give back to your host country, gain a deeper understanding of local issues, and develop a sense of global citizenship. It's a rewarding experience that fosters empathy and reinforces the importance of contributing to the wider world.

    Gaining valuable work experience

    Participating in volunteer and community projects during your exchange program can provide significant work experience that is highly attractive to future employers. These projects often involve teamwork, problem-solving and project management, all of which are essential skills in any professional setting.

    By contributing to local initiatives, you can demonstrate your ability to adapt to new environments, work with diverse teams, and handle responsibility. Furthermore, these experiences can fill gaps in your CV, showcasing your proactive approach to skill-building and community involvement. Engaging in meaningful projects not only supports your personal growth but also highlights your commitment to making a positive impact, a quality greatly valued in any career field.
