Dementia Linked To Beverage Consumed By 50% Of People Every Day

Half of North Americans use a drink linked to dementia on any given day.

Both sugary and artificially sweetened ‘diet’ drinks are linked to dementia by two new studies.

People who drink sugary beverages tend to have poorer memories, smaller brains and a smaller hippocampus (an area vital for learning and memory).

Diet sodas, though, don’t seem much safer.

A follow-up study found that people who drink diet sodas are three times more likely to develop dementia and stroke, compared to those who drink none.

Both studies show associations, so it doesn’t prove cause and effect.

Professor Sudha Seshadri, who led the research, said:

“These studies are not the be-all and end-all, but it’s strong data and a very strong suggestion.
It looks like there is not very much of an upside to having sugary drinks, and substituting the sugar with artificial sweeteners doesn’t seem to help.
Maybe good old-fashioned water is something we need to get used to.”



Excess sugar intake has long been linked to obesity, diabetes  and heart disease.

Its effect on the brain is more of an unknown (although what are the chances it’s going to be good for us?!)

More surprising is the link between diet sodas and dementia.

The researchers suggest it could be down to the artificial sweeteners used.

Sugar is toxic to the brain

This is certainly not the first study to link sugar intake with dementia.

A recent study linked excess sugar intake with Alzheimer’s disease.

It suggested that too much glucose (sugar) in the diet damages a vital enzyme which helps fight the early stages of Alzheimer’s disease.

High blood sugar levels have also been linked to memory problems.

The researchers in this study think that sugar could have a ‘toxic’ effect on the brain.

The studies were published in the journals Stroke and Alzheimer’s & Dementia (Pase et al., 2017; Pase et al., 2017).

Nerd Alert: Reading is Good For Your Health

Clients who seek solace by pouring their hearts out in Alison Kerr Courtney’s office don’t get rewarded with a Xanax or Prozac prescription. Instead, they walk away with a reading list.

The founder of  BiblioRemedy isn’t a licensed therapist, nor is she currently an English teacher, although she did work as one for 10 years in France, and has spent years shelving books at the library and in bookstores.

Courtney is a kind of book whisperer.

For as long as she can remember she’s had a knack for matching people with books that fit with their intellectual interests. But some clients want more when they make an appointment with her at her office in Lexington, Kentucky.

What they seek is a kind of bibliotherapy. It’s a growing trend where people tell empathetic listeners like Courtney their goals or problems. Courtney then suggests books that can help them clarify their goals, work through an emotional issue, or may even help them turn a page to start a newer, healthier life chapter.

“I’ve had clients dealing with grief issues, for example. I pair them up with books I think will most help in their specific situation,” Courtney said.

A recent client dealing with grief told Courtney how much her recommendations helped. Typically Courtney suggests five to seven books. The client said she read every one, except for the ones dealing specifically with grief.

“Not everyone is ready for certain books, and that’s OK,” she said. “They may get there eventually and the other books may help with that process.”

Books can literally change your life and they don’t all have to come from the self-help shelf to work.

Fiction may actually be more powerful, according to a new study running in the journal Trends in Cognitive Sciences.

Books such as Judy Blume’s “Are You There God? It’s Me, Margaret,” or “The Autobiography of Malcolm X,” or Alice Walker’s “The Color Purple,” may teach you about complicated topics such as racism, poverty, teen angst, bullying, sexual orientation or other issues, but they may do even more. They could help you know your own heart and others’.

“People who read fiction may understand people better than others,” said Keith Oatley, a cognitive psychology professor emeritus at the University of Toronto. He’s also an award-winning novelist. “A work of fiction is a piece of consciousness that can pass from one mind to another and that reader can make it their own.”

Books can work as a kind of “moral laboratory” as the scholar Jemeljan Hakemulder calls it, or they can act like the mind’s “flight simulator,” as Oatley describes it.

Reading can help you safely test how you feel about certain issues or people, without your having to experience something directly.

Oatley believes the novels that help people best are the ones that “help us understand the characters from the inside,” rather than more plot-driven novels.

That means we can learn from a book that’s a part of the literary cannon, such as Virginia Woolf’s “Mrs Dalloway,” equally as well as we can learn from popular fiction such as “Harry Potter.”
Spending quality time with these characters as you relax on the beach or sit propped up on bed pillows is more than mere escapism. Reading these books may enhance your emotional intelligence.

That means reading books could improve your love life, your family life, your relationships at work.
That’s because as you learn about Mrs. Dalloway’s worries as she shops for flowers or you witness Harry Potter struggle to control his powers in front of his neglectful muggle family, you contrast that experience with your own.

The characters’ experiences “can be internalized to augment everyday cognition,” according to the study.

In other words, as you read, you think, “‘This person does this and it reminds me of this person I know,’ and when you think deeply in that way, you get better at empathizing with others,” Oatley said. Even if you may never throw the perfect London party or you never meet a moody teenage wizard.

Lab tests seem to show this.

People who have been reading fiction test higher for empathy. Other brain studies of people who listen to a story with intense emotion show a physical response. Their heart rate changes and brain scans show the area that corresponds with emotion lights up, as if the person was experiencing that emotion personally.

Earlier studies have shown that reading can actually develop neural networks in your brain that can help you understand even more complex thought.

Even if you are not a big reader, there’s still hope.

Past studies have shown serial television programs that are character driven such as “The West Wing” or ” The Good Wife” also “can help you better understand what we human beings are up to,” Oatley said. Other studies have shown watching character-driven sitcoms can lessen a viewers’ prejudice.
Natalie Phillips, an assistant professor of English at Michigan State University, said this current study about fiction is exciting and seems to fit with some of the early data she’s gotten from her own lab tests on readers.

Research on this topic, she said, is only the “tip of the proverbial iceberg.” There is still so much more to learn about what fiction can do for us. She does caution that more lab work needs to be done to see if the empathy someone has for a character extends to others beyond the book.

“Because people are feeling something as they read, doesn’t always lead to more positive relationships with someone,” she said. “However, this research marks one of the crucial first steps in that direction toward understanding the intricate cognitive processes involved in literary reading.”

Oatley believes reading can help our emotional development in large part because humans are highly social creatures.

You can be as smart as Sherlock, but to get along well in this life, you really do need to understand people emotionally. And you can’t be as emotionally unavailable as Mr. Darcy throughout much of “Pride and Prejudice.” You have to learn the lesson Jane Austen is trying to teach with that book, Oatley said: To love people, you really have to know them. Perhaps you can do that best by living by the book.

“People say you only get one life,” Oatley said. “But I say read fiction and you can live many lives in one.”

This Fruit Reverses Brain Ageing

A natural compound found in strawberries can reduce the mental effects of ageing.

The antioxidant fisetin, when given to mice, was found to reduce their mental decline with age and inflammation in their body.

Fisetin is also found in many other plants, such as apples, onions, cucumbers and persimmons.

Dr Pamela Maher, who led the research said:

“Companies have put fisetin into various health products but there hasn’t been enough serious testing of the compound.
Based on our ongoing work, we think fisetin might be helpful as a preventative for many age-associated neurodegenerative diseases, not just Alzheimer’s, and we’d like to encourage more rigorous study of it.”

Previous studies in the same lab have found that fisetin can reduce age-related memory loss.

The study was carried out on mice that had been genetically modified to be susceptible to Alzheimer’s disease.

Dr Maher said:

“Mice are not people, of course.
But there are enough similarities that we think fisetin warrants a closer look, not only for potentially treating sporadic AD but also for reducing some of the cognitive effects associated with aging, generally.”

The mice were given food with fisetin in it for 7 months and compared to a control group.

Dr Maher said:

“At 10 months, the differences between these two groups were striking.”

Those given the fisetin had hardly suffered any age-related deficits.

The study was published in the Journals of Gerontology Series A (Currais et al., 2017).

What Happens to Your Brain When You Don’t Get Enough Sleep

If you’re tossing and turning every night, there’s some bad news. Your brain could be in big trouble!

And you thought getting your recommended seven to nine hours of zzz’s was the only thing you needed to worry about. Oddly enough, there are some pretty scary side effects to sleep loss, all around. (By the way, getting too much sleep could be bad for your health, too.)

A study, published in the Journal of Neuroscience, investigated how the brain responds to bad sleep habits using lab mice. Their surprising discovery revealed that not getting enough deep sleep, along with not sleeping at all, can literally cause your brain to start eating itself. No kidding!

The team of researchers, led by neuroscientist Michele Bellesi from the Marche Polytechnic University in Italy, divided the mice into four groups. While the well-rested group slept for six to eight hours, another was periodically woken up from sleep, the third group was kept awake for an extra eight hours, and a final group remained chronically sleep-deprived, staying awake for five days straight.

When the researchers compared brain activity across the four groups, they noted something odd. The neurons of both the well-rested and sleep-deprived groups continued the same healthy brain-cleaning activity that always happens when we sleep. But the brains of the sleep-deprived mice went into overdrive and began harming themselves, too.

Sound crazy? We don’t blame you. But this isn’t news to the scientific community. As we sleep, our brains do more than replenish our energy; they also clear away the toxic byproducts of neural activity from the day. (It’s also why your brain has a delete button!) While we’ve known that this process occurs when we get a good night’s sleep, apparently the same thing can happen when we lose sleep, too. But because of the lack of shut-eye, the brain goes a bit overboard with its cleaning—hence its terrifying self-eating habit.

We have only one conclusion. In the name of your brain’s health, you have a pretty good reason to hit the hay an hour earlier tonight.
