Animal study reveals cadmium exposure and Alzheimer’s risk gene may be linked to cognitive impairment

August 04, 2021 -

The effects of cadmium plus an Alzheimer's risk gene

The so-called human apolipoprotein E (APOE) gene codes for a protein called apolipoprotein. This combines with fats to form lipoproteins, which carry cholesterol through the bloodstream. The APOE4 gene is a variant of the APOE gene. It significantly raises a person's risk of developing Alzheimer's, which is why it is considered an Alzheimer's risk gene.

For their study, the researchers wanted to know how being ...

Harvard study: Mediterranean diet slashes Alzheimer’s risk by 35% in highest genetic risk group

August 27, 2025 -

For decades, people carrying the APOE4 gene—the strongest known genetic risk factor for Alzheimer’s—have been told their fate was sealed. If you inherited one copy, your risk tripled or quadrupled. Two copies? A twelvefold increase in dementia risk compared to those without the gene. Doctors offered little hope beyond "wait and see," leaving millions feeling powerless against their own DNA.

But a groundbreaking Harvard study just flipped ...

Study looks at the link between inflammation and the spread of Alzheimer’s

November 01, 2018 -

However, scientists are learning more about possible causes of the illness, shedding light on potential avenues for treatment in the future. According to research carried out by scientists from UMass Medical School and the University of Bonn, inflammation is linked to the spread of the disease throughout the brain.

In Alzheimer’s disease, plaques made up of beta-amyloid peptides build up in the brain. These toxic plaques cause the neurons around them to die and lead ...

Your plate, your fate: Mediterranean diet defies genetic destiny in Alzheimer’s prevention

September 05, 2025 -

In a groundbreaking development that challenges the notion of genetic fate, a new study reveals that a Mediterranean-style diet can significantly reduce the risk of Alzheimer's disease, even for individuals carrying the highest-known genetic risk factor. The research, published in the prestigious journal Nature Medicine, offers a powerful, accessible strategy for millions to take control of their long-term brain health through lifestyle choices.

Scientists say eating eggs for breakfast helps boost brain function

March 13, 2019 -

Previous research has linked regular egg consumption to heart attacks, high blood pressure, and weight gain. Conditions that cause damage to the heart, arteries, or blood circulation are also known to increase the risk of Alzheimer's disease.

According to the American Heart Association, healthy adults should not consume more than 300 milligrams of cholesterol a day. One large egg has around 186 milligrams of cholesterol and a small egg around 141 milligrams. A new study ...

Eating eggs and other sources of dietary cholesterol NOT linked to risk of stroke, according to study

November 11, 2019 -

Certain cholesterol-dense foods have therefore caused a lot of controversy over the years, including butter, certain oils, and eggs. At one point we were advised to avoid eating eggs altogether, and in more recent years have been admonished to limit our consumption of this protein-packed food.

Now, a study by researchers from the University of Eastern Finland, published in the American Journal of Clinical Nutrition, has found that eggs and other sources of dietary cholesterol ...

Dr. Michael Nehls proposes Unified Theory of Alzheimer’s Disease (UTAD) to prevent, cure dementia

January 02, 2024 -

Dr. Michael Nehls, author of the book "The Indoctrinated Brain," presents a speculative primer into the causes of Alzheimer's. The primer integrates all key behavioral, genetic and environmental risk factors "in a causal chain of etiological and pathogenetic events" in order to develop a sound scientific approach for preventing and treating dementia.

The UTAD that Dr. Nehls proposes is based on three concepts that derive from the evolutionary history of humans. These ...

Regular tea consumption linked to healthy cognitive function: Study

August 03, 2020 -

The study published in the journal Aging found that the brain regions were better interconnected, which made the processing of information more efficient.

"Our results offer the first evidence of positive contribution of tea drinking to brain structure, and suggest that drinking tea regularly has a protective effect against age-related decline in brain organization," added Feng Lei, the team leader of the study.Better brain organization explains improved cognition ...

Tiny particles from city air invade peoples brains, interfere with cognition

February 12, 2017 -

Natural News previously reported that by 2050, an estimated 135 million people around the world will suffer from Alzheimer's disease or other forms of dementia. Currently, about 44 million people worldwide have this affliction, which is obviously reaching epidemic proportions as the population ages. Dementia and Alzheimer's disease have overtaken heart disease as the leading cause of death globally. More than five million cases of Alzheimer's have been diagnosed in the U.S....

Breakdown of sleep quality and key brain regions tied to Alzheimer’s risk: A new call for prioritizing rest

July 28, 2025 -

In the early hours of July 25, 2025, a landmark study in the Journal of Clinical Sleep Medicine reignited the urgent conversation about the connection between sleep quality and cognitive decline. Led by postdoctoral fellow Gawon Cho at Yale School of Medicine, the research tracked 270 adults for over a decade and revealed a disturbing link: spending less time in restorative deep sleep (SWS) and REM sleep correlates with shrinkage in brain regions prone to ...

Toxic particles from air pollution causing people’s brains to swell… “city life” linked to brain deterioration

February 04, 2017 -

Beyond its environmental effects, air pollution is known for being harmful to the respiratory and circulatory systems. Toxic air pollutants like sulfates, nitrates, and black carbon can penetrate deep into lung and cardiovascular tissues, which poses a serious risk to human health. Outdoor air pollution is regarded as the top single killer in the world -- causing up to 3 million deaths per year.

Now, new research has shown that the hazardous effects don't stop there: ...

Omega-3 intake linked to better brain health, study finds

2 months ago -

As interest in nutrition and cognitive health grows, dietitians are emphasizing the role of omega-3 fatty acids – healthy fats that support brain structure, function and long-term mental performance.

Omega-3 fatty acids are considered essential nutrients, meaning the body cannot produce them on its own. They include three main types: docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA) and alpha-linolenic acid (ALA). DHA and EPA are primarily found ...

The unseen shield: How finding your purpose can protect your brain from dementia

September 20, 2025 -

A groundbreaking new study suggests one of the most potent defenses against cognitive decline is not a pharmaceutical, but a profoundly human experience: a strong sense of purpose. This research offers a paradigm-shifting approach to brain health, emphasizing psychological well-being as a critical component in the fight against Alzheimer's disease and other forms of dementia.

The study, published in the American Journal of Geriatric Psychiatry, ...

The mouth-brain connection: Could dental health guard against dementia (and vice versa)?

May 15, 2025 -

A growing body of research suggests that the health of our mouths may hold clues—and keys—to preserving cognitive function as we age. Recent studies reveal that harmful oral bacteria from gum disease can migrate to the brain, triggering inflammation and contributing to conditions like Alzheimer’s. From the University of Exeter to Tohoku University, scientists are uncovering the intricate ties between periodontal health and brain health, challenging the notion ...
