Study Shows Education Can Reduce Risk Of Alzheimer’s Disease

“Older people who aren’t in the position to go back to school can reduce their Alzheimer’s risk by working longer.”

According to the Centers for Disease Control, over 5.4 million Americans have Alzheimer’s disease. As a result of the country’s aging population, this progressive brain disorder has grown to be the the sixth leading cause of death among all adults and the fifth leading cause for those aged 65 or older. Although there is no cure for this debilitating disease, a new study has found a way to reduce the risk of developing it: education.

A Cambridge University study of over 54,000 people found that every year spent in school reduces the chances of being diagnosed with Alzheimer’s disease later in life by 11%. According to study co-author Dr. Susanna Larsson, from the Karolinska Institute in Sweden, “Evidence suggests that education helps improve brain networks and thus could increase [cognitive] reserve.”

People who’ve spent more time in school have a greater resiliency against degenerative brain disorders because they have more neurological connections to fall back on. Those with fewer connections — or less cognitive reserve — are forced to rely on poorer formed connections which can exacerbate the spread of dementia.

Older people who aren’t in the position to go back to school can reduce their Alzheimer’s risk by working longer. A 2013 study found that those who delay retirement are less likely to develop the disease. “For each additional year of work, the risk of getting dementia is reduced by 3.2%,” Carole Dufouil, a scientist at INSERM, the French government’s health research agency, said.

The answer to preserving one’s cognitive function appears to be “use it or lose it.” Those who keep their brains active and continue building connections throughout their lives have a better chance of maintaining their cognitive abilities as they age. It’s life’s big reward for staying busy, being open to change, and living life to its fullest.

If you are totally ready to move on from Donald Trump, you're not alone. According to a report last April from the Wason Center National Survey of 2020 Voters, "President Trump will be the least popular president to run for reelection in the history of polling."

Yes, you read that right, "history of polling."

After three years on the sidelines, Colin Kapernick will be working out for multiple NFL teams on Saturday, November 16 at the Atlanta Falcons facility.

The former 49er quarterback who inflamed the culture wars by peacefully protesting against social injustice during the national anthem made the announcement on Twitter Tuesday.

Kaepernick is scheduled for a 15-minute on-field workout and an interview that will be recorded and sent to all 32 teams. The Miami Dolphins, Dallas Cowboys, and Detroit Lions are expected to have representatives in attendance.

"We like our quarterback situation right now," Miami head coach, Brian Flores said. "We're going to do our due diligence."

NFL Insider Steve Wyche believes that the workout is the NFL's response to multiple teams inquiring about the 32-year-old quarterback. A league-wide workout would help to mitigate any potential political backlash that any one team may face for making an overture to the controversial figure.

Kapernick is an unrestricted free agent (UFA) so any team could have reached out to him. But it's believed that the interested teams are considering him for next season.

Earlier this year, Kaepernick and Carolina Panthers safety Eric Reid reached a financial settlement with the league in a joint collusion complaint. The players alleged that the league conspired to keep them out after they began kneeling during the national anthem in 2016.

Before the 2019 season, Kaepernick posted a video of himself working out on twitter to show he was in great physical condition and ready to play.

Kaepnick took the 49ers to the Super Bowl in 2012 and the NFC Championship game in 2013.

He has the 23rd-highest career passer rating in NFL history, the second-best interception rate, and the ninth-most rushing yards per game of any quarterback ever. In 2016, his career to a sharp dive and he won only of 11 games as a starter.


In the category of "claims to fame nobody wants," the United States can now add "exporter of white supremacist ideology" to its repertoire. Super.

Russell Travers, acting director of the National Counterterrorism Center, made this claim in a briefing at The Washington Institute in Washington, D.C. "For almost two decades, the United States has pointed abroad at countries who are exporters of extreme Islamist ideology," Travers said. "We are now being seen as the exporter of white supremacist ideology. That's a reality with which we are going to have to deal."
