Has Dr. Donald Weaver lost his mind? How can he possibly suggest Alzheimer’s isn’t a brain disease?

But hold on. What he’s saying about the cause of Alzheimer’s disease makes more sense than appears at first sight.

Although the disease shows up in the brain, its foundation might lie elsewhere. And that’s within the immune system. Dr. Weaver argues that Alzheimer's is an autoimmune disease that attacks the brain.

Take a look at any list of risk factors for cognitive decline and you're bound to find "education" among them. The more years you spend in education, the lower your risk of cognitive decline in old age. However, the latest research begs to differ.

Cognitive decline is not only going to impair your chess or sudoku, it can reach a point where it severely affects your everyday activities. When this happens, doctors start talking about dementia.

More than a billion adults around the world live with elevated blood pressure, a condition that puts individuals at risk of damaging a variety of organs, including the nervous system.

Though previous studies have linked high blood pressure (hypertension) with an increased risk of cognitive impairment, the mechanisms behind the decline in mental health has never been known.

Now an international team of researchers has discovered which areas of the brain are most likely to suffer damage as the cardiovascular system is put under strain.

It’s no secret that certain nutrients are good for your brain. Nutrients like vitamin B-12, vitamin D, and omega-3 fatty acids are often touted for staving off Alzheimer’s and other memory-robbing diseases.

Now we know there’s another vitamin to add to that list of nutritional memory-saving superstars. An international group of researchers has recently found a certain miracle nutrient could help you reverse Alzheimer’s and other degenerative diseases.

Vitamin K has been getting a lot of attention the last few years. You’ve probably heard that vitamin K is essential for blood clotting. And you might’ve heard how it can also improve your heart health.

And now you’re about to learn how vitamin K could be the next big thing in Alzheimer’s treatment and prevention.

Neurologists at a memory clinic in China have diagnosed a 19-year-old with what they believe to be Alzheimer's disease, making him the youngest person in the world to be diagnosed with the condition.

The male teenager began experiencing memory problems around age 17, and the cognitive decline only worsened over the years.

No one wants to get that call…

You know, the one where your doctor tells you, “It’s dementia… and it’s not going to get any better.”

That’s because this life-changing disease can slowly strip away your health and independence.

Fortunately, new research shows there’s a “leisurely” way to end dementia before it starts. And it couldn’t be easier or more enjoyable.

When children don’t pay attention, act impulsively, or are hyperactive - a doctor may diagnose ADHD and prescribe medication to help them have better focus, control their impulses and feel more calm.

There are a number of drugs available to help both children and adults with ADHD, but one in particular is catching the eye of researchers for its ability to also help people with Alzheimer’s disease.

An experimental drug (lecanemab) for Alzheimer's disease from Eisai and Biogen slowed cognitive decline in a closely watched trial, however, it may carry a risk of dangerous side-effects for certain patients, according to new data presented last week.

It's known that keeping your brain active through brain games can stave off age-related memory loss. But there’s a different kind of “brain activity” you’ll want to avoid for better longevity.

Too much electrical activity in your brain is linked to numerous disorders ranging from autism and epilepsy to Alzheimer’s disease.

Taking a daily multivitamin and mineral tablet may slow the gradual cognitive decline that happens naturally as we get older.

At the end of a three-year trial, people who had taken a commercially available multivitamin-mineral supplement had a cognitive age that was 1.8 years younger than those who took a placebo.

For more than 15 years, the global scientific community researching Alzheimer’s Disease has focused its attention—and hundreds of millions of research dollars—on the theory that the disease is primarily caused by the build-up of plaque, called amyloid beta, in the brain. But what if that theory is based on flawed data?

A six-month investigation by Charles Piller, an award-winning reporter for Science magazine, finds that key research published in 2006 may have included fabricated data.
