Three old-school methods to fight dementia, proven by new studies – Inverse

Published

Getting enough sleep

While exercise and new experiences may help protect the brain during waking, another study published Tuesday in the journal Neurology shows that the unconscious hours may be just as important, even for people in their early twenties.

A small exploratory study on 15 men, all 22 years-old, in Sweden, found that reducing just one-night total sleep deprivation increased the level of tau protein in the blood by 17.2 percent. Tau is a protein linked to Alzheimer’s in the brain when it’s functioning abnormally. On a night of normal sleep, tau increased by 1.8 percent.

Jonathan Cedernaes is a neuroscientist at the Uppsala University in Sweden and the study’s senior author. He tells Inverse that this isn’t a large enough increase to be immediately concerning. Rather, it points to the idea that the brain has a “rhythm” that sets healthy levels of tau release, and that this system can be tinkered with in young healthy people.

Cedernaes explains that later in the evening we may have naturally high tau release. During sleep, the brain may “clear out” the tau that’s formed during that period. We already know that the brain does have a type of “rinse cycle” during sleep, during which cerebrospinal fluid washes through the brain, clearing it of harmful proteins.

“If we instead stay awake when we should normally sleep, this may result in competing processes, as we have sustained release of tau when it should normally not be released any longer,” Cedernaes says. “This could result in altered clearance of tau from the brain, and this may then spill over into the circulation, which is what we measured here.”

These results are just the beginning, and we don’t know how results like Cedernaes’ will play out in the long-term. For now, they point to the idea that sleep may be a major part of keeping the brain resilient against the biomarkers of Alzheimer’s.

“The most important message may be more and more evidence indicates that sleep is a factor to consider in the context of lifestyle factors that influence the risk of Alzheimer’s disease,” he says.

But take note — there’s no predetermined trajectory

These old-school techniques may not feel particularly futuristic, but we shouldn’t let their low-tech nature obscure their effectiveness. They may not be the futuristic cure-all, but they can prolong lucidity to experience moments that could otherwise be lost.

“There may be no ‘predestined trajectory’ when it comes to brain health, and hopefully these data empower them to make healthy lifestyle choices that could help support their brain health longevity every day,” says Casaletto.

Hospitals in Saskatchewan face prolonged COVID-19 crisis, modelling shows

Published

 on

COVID-19 patients will keep crowding hospital intensive care units (ICUs) in the Canadian province of Saskatchewan well into next year without government orders to limit public mixing, modelling data showed on Wednesday.

As the pandemic ebbed during the summer, the western farming and mining province lifted restrictions at the fastest rate in Canada along with neighbouring Alberta. Saskatchewan has since become the country’s  COVID-19 hotspots, with the lowest vaccination rate among provinces, and had to hastily reimpose restrictions such as masking in indoor public places.

“I have no shame in pleading to the public, that we’ve gone so far and we just have to pull along for the next weeks and months,” said Saskatchewan’s Chief Medical Health Officer Dr. Saqib Shahab, who broke down with emotion during a media briefing. “It is distressing to see what is happening in our ICUs and hospitals and I’m sorry — it’s a very challenging time.”

The pandemic’s spread has forced Saskatchewan to fly some COVID-19 patients to Ontario for care and to cancel thousands of surgeries.

Saskatchewan’s modelling showed that severe cases will continue to overwhelm ICUs until March before beginning to decline, without a reduction in mixing, such as smaller gatherings, and greater access to vaccine booster shots. Reduced mixing should ideally last at least 28 days, Shahab said.

The provincial government, led by Premier Scott Moe, has declined to impose limits on private gatherings, however.

Canada’s daily case counts spiked in late summer, but have declined recently. Cases in Saskatchewan and Alberta have also started trending lower, however they have still recorded the highest rates of deaths among the 10 provinces in the past week, and the highest rates of active cases.

SHA says COVID-19 protocols prevented a flu season last year – moosejawtoday.com

Published

 on


The Saskatchewan Health Authority says last year’s flu season was prevented thanks to masks, physical and social distancing, and increased hand washing.

Dr. Tania Diener, the COVID-19 Immunization Co-Chief at the province’s Emergency Operations Centre, says that, “We effectively didn’t have a flu season here last year.”

With restrictions slowly lifting from a population feeling the stress of isolation and public health measures, the province is uncertain about whether or not a flu season will return this winter.

Dr. Diener emphasized that, “Our hospitals are already under strain due to the number of cases of COVID-19, especially among those who are unvaccinated, due to the new Delta variant. A further influx of people sick with influenza would further strain those resources, so we’re asking everyone to get their flu vaccine again this year.”

SHA says they have enough evidence at this point to conclude that receiving a COVID-19 vaccine and a flu vaccine together is safe, and they encourage everyone able to do so to get both vaccines as soon as possible. 

This year’s flu vaccine is quadrivalent, meaning it protects against four different flu variants, an improvement from last year’s, which was trivalent. 
Information on this year’s flu vaccine can be found here.

Province says flu shots prevents serious illness, deaths – My Comox Valley Now

Published

The province wants you to roll up your sleeves for another kind of vaccine as we head into flu season.

Health officials are hoping you will take their advice and get a flu shot, which is free for everyone in B.C. older than six months.

They say the unique circumstances of the COVID-19 pandemic and the strain it has put on the health-care system continue to make influenza immunization a priority.

“All British Columbians should get vaccinated against influenza to protect themselves and their loved ones from serious illness, to reduce the strain on our hard-working health workers and to do our part to make sure the health system continues to be there for people who need it, where they need it and when they need it,” said health minister Adrian Dix. 

“I’m grateful to all of our health-care workers, including physicians, pharmacists, nurses, nurse practitioners and others for how they help people get immunized to protect themselves and those they care about.”

Seasonal influenza and other respiratory viruses will be in communities alongside COVID-19 this fall and winter.

The province says it “has the potential to escalate pressures already faced by the health-care system, particularly if the effects from COVID-19 and seasonal influenza occur are the same.”

That is why vaccines are now available and the province continues to increase vaccine accessibility through many locations and vaccine providers throughout B.C.

“This year, it’s especially important for people to get vaccinated against influenza. Last year’s low influenza rates means our immunity against influenza is lower than usual,” said provincial health officer, Dr. Bonnie Henry. 

“Getting your influenza vaccine this year is more important than ever to protect yourself, your community and our overstretched health-care system.”

Pharmacies around B.C. have played a key role in providing easy access to influenza vaccines since 2009. 

This year, vaccines are available to pharmacies through a direct-distribution model. 

This means pharmacies are able to order them directly from distributors, which the province says makes “influenza immunization easier and more flexible for people in B.C.”

“Pharmacists played a key role in helping people get immunized against COVID-19 earlier this year and administered the majority of influenza doses last year,” said Geraldine Vance, CEO, B.C. Pharmacy Association. “We’re proud of the role we continue to play in protecting our health-care system and keeping everyone safe.”

Flu vaccines have been available already for certain high-risk groups. 

As they become available more broadly to the public throughout the province, you’re asked to check their health authority’s website or call their health-care provider or pharmacist to check for availability and to make an appointment.
