This article is about a study suggests that bilingualism can possibly decrease chances of getting dementia and cognitive decline in older people. The study was published in the journal Neurobiology of Aging. It hypothesized that because bilingual people can switch between two languages seamlessly, it can be used in multitasking, self-control, emotion management, possibly delaying dementia. However, the study only focused on bilingual people who use two languages everyday for a long time. Because of the different degrees of bilingualism, it's difficult to know if it really can delay dementia.

This article talks about the complexities of language in dementia patients, specifically the fact that they are most likely to revert to their primary language as their condition progresses. The study that was done for this article also expands on the possibility that speaking two or more languages can delay the onset of dementia for an average of five years.

People familiar with more than one language showed a later onset of dementia, according to a new study from Indian researchers. Multilingualism appeared to stave off dementia onset in several diagnostic categories, including front temporal and vascular dementia as well as Alzheimer's, according to the researchers' report in the online version of Neurology.

This article discusses whether becoming bilingual can delay the onset of Alzheimer's disease and dementia by up to 5 years. It is believed that learning another language improves functions like attention and alertness. Since a bilingual brain is constantly working, the brain becomes more resilient to the impairments caused by diseases. The article also mentions contradicting research that provides a different perspective on this topic.

Here's some good news for the bilingual folks. You may have a better chance of delaying the onset of several different dementias, just by speaking a second language, a new study says.

A 2022 University of Cambridge study conducted by Sahakian, Langley, Chen, et al., and published in the journal _Neurology_, shows that that social isolation is linked to changes in brain structure and cognition - the mental process of acquiring knowledge - it even carries an increased risk of dementia in older adults. Previous research established that brain regions consistently involved in diverse social interactions are strongly linked to networks that support cognition, including the default mode network (which is active when we are not focusing on the outside world), the salience network (which helps us select what we pay attention to), the subcortical network (involved in memory, emotion and motivation) and the central executive network (which enables us to regulate our emotions). This particular study examined how social isolation affects grey matter - brain regions in the outer layer of the brain, consisting of neurons. It investigated data from nearly 500,000 people from the UK Biobank, with a mean age of 57. People were classified as socially isolated if they were living alone, had social contact less than monthly and participated in social activities less than weekly. The study also included neuroimaging (MRI) data from approximately 32,000 people. That data revealed that socially isolated people had poorer cognition, including in memory and reaction time, and lower volume of grey matter in many parts of the brain. These areas included the temporal region (which processes sounds and helps encode memory), the frontal lobe (which is involved in attention, planning and complex cognitive tasks) and the hippocampus - a key area involved in learning and memory, which is typically disrupted early in Alzheimer's disease. We also found a link between the lower grey matter volumes and specific genetic processes that are involved in Alzheimer's disease. Follow-ups with participants 12 years later showed that those who were socially isolated, but not

Younger you are, the better the linguist you are. Multilingual brain is "nimbler, quicker, better able to deal with ambiguities, resolve conflicts and even resist Alzheimer's disease and other forms of dementia."

Study examined the medical records of 648 Alzheimer's patients in Hyderabad and found that bilinguals developed dementia four to five years later than monolinguals. 

The largest study so far to ask whether speaking two languages might delay the onset of dementia symptoms in bilingual patients as compared to monolingual patients has reported a robust result. Bilingual patients suffer dementia onset an average of 4.5 years later than those who speak only a single language.

Learning a foreign language has many more benefits than you would think. This article highlights many of the cognitive benefits associated with learning a foreign language.

This article gives a rundown on 7 cognitive advantages of bilingualism: 1. You become smarter: speaking a foreign language improves the functionality of your brain by challenging it to recognise, negotiate meaning, and communicate in different language systems. 2. You build multitasking skills. 3. You stave off Alzheimer's and dementia. 4. Your memory improves. 5. You become more perceptive. 6. Your decision-making skills improve. 7. You improve your first language (L1)

What does recent research say about the potential benefits of bilingual education? Here are the main 6 findings: 1. Attention: "[Bilinguals] can pay focused attention without being distracted and also improve in the ability to switch from one task to another," says Sorace. Do these same advantages accrue to a child who begins learning a second language in kindergarten instead of as a baby? We don't yet know. Patterns of language learning and language use are complex. But Gigi Luk at Harvard cites at least one brain-imaging study on adolescents that shows similar changes in brain structure when compared with those who are bilingual from birth, even when they didn't begin practicing a second language in earnest before late childhood. 2. Empathy: bilingual children as young as age 3, because they must follow social cues to figure out which language to use with which person and in what setting, have demonstrated a head start on tests of perspective-taking and theory of mind - both of which are fundamental social and emotional skills. 3. Reading (English): students enrolled in dual-language programs outperformed their peers in English-reading skills by a full school year's worth of learning by the end of middle school. 4. School performance and engagement: compared with students in English-only classrooms or in one-way immersion, dual-language students have somewhat higher test scores and also seem to be happier in school. Attendance is better, behavioral problems fewer, parent involvement higher. 5. Diversity and integration: Because dual-language schools are composed of native English speakers deliberately placed together with recent immigrants, they tend to be more ethnically and socioeconomically balanced. And there is some evidence that this helps kids of all backgrounds gain comfort with diversity and different cultures. 6. Protection against cognitive decline and dementia: actively using two languages seems to have a protective effect against age-related demen

Ryan, you're the best!

Listening to music can be therapeutic but making music can literally be a form of therapy for deteriorating brains. Music shows to be an effective in helping long-term depression and dementia.

This study shows that bilingualism can delay the onset of symptoms of dementia by about 4-5 years compared with monolinguals. They still get the disease, but they're able to cope longer than monolinguals once they get it.

This was an interesting article I used for my Smorgasboard project. I wanted to study how dementia affects our ability to speak and understand language. This article covered different types of aphasia, or loss of language that occur when one has either Alzheimer's or other types of dementia.

For bilinguals, because both languages are active in the brain, the act of keeping the two languages separate sharpens the executive control system. Strengthening this area may have long-term benefits: namely, performing better on a variety of cognitive tasks and possibly delaying the onset of dementia later in life.

This article is relevant to the Genie case, outlining the many ways isolation is physically bad for us. Chronically lonely people have higher blood pressure, are more vulnerable to infection, and are also more likely to develop Alzheimer's disease and dementia. Loneliness also interferes with a whole range of everyday functioning, such as sleep patterns, attention and logical and verbal reasoning. The mechanisms behind these effects are still unclear, though what is known is that social isolation unleashes an extreme immune response - a cascade of stress hormones and inflammation. This response might've been biologically advantageous for our early ancestors, when being isolated from the group carried big physical risks, but for modern humans, the outcome is mostly harmful. A 1957 McGill University study, recreated in 2008 by Professor Ian Robbins, head of trauma psychology at St George's Hospital, Tooting, found that after only a matter of hours, people deprived of perceptual stimulation and meaningful human contact, started to crave stimulation, talking, singing or reciting poetry to themselves to break the monotony. Later, many of them became anxious or highly emotional. Their mental performance suffered too, struggling with arithmetic and word association tests. In addition, subjects started hallucinating. The brain is used to processing large quantities of data, but in the absence of sensory input, Robbins states that "the various nerve systems feeding in to the brain's central processor are still firing off, but in a way that doesn't make sense. So after a while the brain starts to make sense of them, to make them into a pattern." It tries to construct a reality from the scant signals available to it, yet it ends up building a fantasy world.

Nice overview of the neurological and other benefits conferred by bilingualism. Being fluent in two languages, particularly from early childhood, not only enhances a person's ability to concentrate, but might also protect against the onset of dementia and other age-related cognitive decline. More recently, scientists have discovered that bilingual adults have denser gray matter (brain tissue packed with information-processing nerve cells and fibers), especially in the brain's left hemisphere, where most language and communication skills are controlled. The effect is strongest in people who learned a second language before the age of five and in those who are most proficient at their second language. This finding suggests that being bilingual from an early age significantly alters the brain's structure.

Around the world more than half (around 60 to 75 percent) speak at least two languages. Most countries have more than one official national language. For example south Africa has 11. So being monolingual like most native english speakers are, we are becoming the minority.

Multilingualism serves an extremely practical purpose. Languages change and develop through social pressures. Over time, different groups of early humans would have found themselves speaking different languages. Then, in order to communicate with other groups - for trade, travel and so on - it would have been necessary for some members of a family or band to speak other tongues. We can get some sense of how prevalent multilingualism may have been from the few hunter-gatherer peoples who survive today. "If you look at modern hunter-gatherers, they are almost all multilingual," says Thomas Bak, a cognitive neurologist who studies the science of languages at the University of Edinburgh. "The rule is that one mustn't marry anyone in the same tribe or clan to have a child - it's taboo. So every single child's mum and dad speak a different language." The article also provides a useful summary of the benefits of speaking at least one other language: bilinguals outperform monolinguals in a range of cognitive and social tasks from verbal and nonverbal tests to how well they can read other people. Greater empathy is thought to be because bilinguals are better at blocking out their own feelings and beliefs in order to concentrate on the other person's. Bilingualism can also delay the onset of dementia and increase cognitive recovery after a stroke. And in addition to social and cultural benefits, bil

While brain games can't avert dementia in those genetically inclined toward the condition, one can ensure better brain fitness and long-term health. The brain thrives on continuous stimulation. Here are takeaway tips from the article: 1. Brain exercises should rely on novelty and complexity, including board games that are played with others. 2. All kinds of concentrated activities, like learning a foreign language or how to play a musical instrument, can be fulfilling. 3. Along with exercising and good nutrition, a brain that is fully engaged socially, mentally and spiritually is more resilient. 4. New, interactive learning is helpful. 5. Cognitive training that uses thinking, such as problem solving and learning, like reading a newspaper article and discussing it with a friend, has staying power in the brain - even 10 years after the training ends.
