Health & FitSpeaking four or more languages could reduce the risk of dementia finds new study
These commonly prescribed medications may increase your risk of dementia, study finds
A study published Monday found a link between dementia and certain medications, including antidepressants, antipsychotics and antiepileptic drugs.
New Canadian research has found that having a strong ability for learning languages may help to reduce an individual's risk of developing dementia.
Carried out by researchers at the University of Waterloo, the new study looked at 325 Roman Catholic nuns in the United States who were taking part in the larger, internationally recognized Nun Study, which is a longitudinal study of religious sisters aged 75 and over.
The nuns were asked to report on how many languages they spoke, and 106 samples of the nuns' written work was also provided for analysis.

How to discuss dementia fears early
The findings, published in the Journal of Alzheimer's Disease, showed that just six percent of the nuns who spoke four or more languages developed dementia, compared to 31 percent of those who only spoke one language.
However, speaking two or three languages did not appear to have a significant effect on reducing dementia risk in this study, a finding which goes against those found in some previous studies.
When the researchers analyzed the nuns' written work, they found that written linguistic ability appeared to have an even greater effect on reducing dementia risk than the ability to speak different languages.
"The Nun Study is unique. It is a natural experiment, with very different lives in childhood and adolescence before entering the convent, contrasted with very similar adult lives in the convent," explained lead author Suzanne Tyas. "This gives us the ability to look at early-life factors on health later in life without worrying about all the other factors, such as socioeconomic status and genetics, which usually vary from person to person during adulthood and can weaken other studies."
Maintaining four out of five habits reduce risk of dementia
Preliminary work presented at the Alzheimer's Association annual meeting suggests picking up multiple healthy habits is more protective against dementia than just one.
"Language is a complex ability of the human brain, and switching between different languages takes cognitive flexibility. So it makes sense that the extra mental exercise multilinguals would get from speaking four or more languages might help their brains be in better shape than monolinguals," says Tyas.
"This study shows that while multilingualism may be important, we should also be looking further into other examples of linguistic ability," said Tyas. "In addition, we need to know more about multilingualism and what aspects are important -- such as the age when a language is first learned, how often each language is spoken, and how similar or different these languages are. This knowledge can guide strategies to promote multilingualism and other linguistic training to reduce the risk of developing dementia."

LGBT People More Likely to Develop Dementia, New Study Finds
The UCSF study found that LGBT people were 29 percent more likely to report memory loss, confusion and other symptoms than their straight, cisgender counterparts. More than 44,000 adults between the ages of 45 and 80 were interviewed across nine different states. Only 3 percent of those polled identified as LGBT, but researchers found about one in seven of them reported cognitive issues. On the other hand, only about one in ten straight people reported a decline. The study also showed LGBT people were nearly 60 percent more likely to live alone and 59 percent more likely to not have a caregiver.
Red wine reduces the risk of dental problems
A study published on February 21, 2018 in the Journal of Agriculture and Food Chemistry, comes to demonstrate that red wine reduces the risk of oral problems through these antioxidants. Problem: A second study proves that alcohol can drive you crazy. The dilemma is total.
Definitely, theis at the heart of all concerns. We already knew that it was effective in losing weight, we now discover that it reduces some problems. Antioxidants in red wine (caffeic acid and paracoumaric acid) are effective against some bacteria in the mouth. They work against gum lesions and cavities. To reach this conclusion, Spanish researchers confronted these two acids with the bacteria in question. They then found that in their presence, the bacteria receded, but they still do not know why. They specify that the tests were performed outside the human body, and therefore, additional research must be done before serious conclusions can be drawn.
Moreover, a second study, conducted in French hospitals between 2008 and 2013, showed that regular and excessive consumption of, 6 glasses per day for men and 4 for women, greatly increases the risk. of dementia. Of more than 57,000 cases of early (ie observed before age 65) dementia, half were directly related to . Involved: the blood pressure, which is higher when you drink it, and increases the risk of vascular dementia. Clearly, drinking can make you crazy, but the wine can have beautiful teeth: we can not have everything!
And of course, we remind you that alcohol is to be consumed in moderation!
Controlling blood pressure may help ward off dementia.
Keeping your blood pressure under control "may be a key to your future brain health," researchers say
