A recent study has revealed significant insights into the early brain changes associated with Alzheimer’s disease, focusing on volume loss in key brain regions. The researchers found that volume loss in the basal forebrain and hippocampus is more pronounced in individuals with high levels of amyloid-beta, a protein linked to Alzheimer’s, even before cognitive symptoms become apparent. The effect of amyloid-beta concentration on the pace of brain shrinkage (volume loss) varied between brain regions. The study was published in the Neurobiology of Aging.

The ovaries are involved in far more than just reproduction. The two oval-shaped glands that float on either side of the uterus don't just produce and release eggs, they also pump out hormones that help keep a person's heart, bones, brain, and immune system healthy as they age. A new...

Losing Both Ovaries Could Come at a Serious Cost to The Brain, Researchers Find

Early memory complaints, validated by partners, are linked to increased tau tangles in the brain, emphasizing the potential of early Alzheimer’s detection and intervention. Individuals who report early memory problems and whose partners also suspect they have memory problems have higher levels of tau tangles in the brain, a biomarker associated with Alzheimer’s disease. This is according to a study published in the May 29, 2024, online issue of Neurology, the medical journal of the American Academy of Neurology.

These Signs of Memory Loss Could Actually Predict Alzheimer’s Brain Changes

By 2050, 60% of US adults could be affected by heart disease and stroke, according to a June 2024 announcement from the American Heart Association (AHA). “The last decade has seen a surge of cardiovascular risk factors such as uncontrolled high blood pressure, diabetes and obesity, each of which raises the risks of developing heart disease and stroke,” Dhruv S. Kazi, MD, MS, associate director of the Richard A. and Susan F. Smith Center for Outcomes Research in Cardiology and director of the cardiac critical care unit at Beth Israel Deaconess Medical Center in Boston, says in the AHA’s press release. So how can we manage those risk factors?

New Research: If You’re Deficient in This Vitamin, It Could Raise Your Stroke Risk by 28%

Low-calorie sweeteners are having a rough go as of late. Last July, the World Health Organization warned of aspartame’s possible cancer-causing properties in humans. (Our analysis of that here.) Now, researchers have found a link between consuming large amounts of the low-calorie sweetener xylitol and an increased risk of heart attack, stroke, and death. Xylitol is a sugar alcohol that sweetens many reduced-sugar foods, baked goods, chewing gums, and toothpastes. The team, led by researchers at the Cleveland Clinic, published their findings today in the European Heart Journal.

High xylitol levels may increase cardiovascular risks by promoting clotting, according to Cleveland Clinic research. Xylitol is a common zero-calorie sweetener found in sugar-free candy and toothpaste. Cleveland Clinic researchers discovered that higher amounts of the sugar alcohol xylitol are associated with an increased risk of cardiovascular events like heart...

Article written by Emily Spencer, Edinburgh Napier University. Imagine a future where the smell of menthol could alleviate some of the worst symptoms of Alzheimer’s disease. This might sound like science fiction, but innovative new research is making it a potential reality. Scientists have discovered that when mice with...

Autism is popularly perceived as a genetic condition that impacts the functioning of various brain mechanisms. The amygdala theory of autism states that autistic individuals differ in the functioning of their amygdala. Researchers suggest more complex differences in a network of structures connected with the amygdala. The amygdala is a...

Changes in how regions of the brain interact with each other, which occur during the surgical procedure for deep brain stimulation (DBS), can temporarily ease motor symptoms of Parkinson’s disease, even before the electrical stimulation is turned on, a study finds. The microlesion effect, as this temporary improvement is...

New research published in the journal Aging Cell sheds light on the potential of exercise to prevent or slow down cognitive decline associated with aging. This study found that exercise can significantly alter the gene expression of aged microglia, a type of brain cell, reverting them to a more youthful state.

New neuroscience research reveals the remarkable impact of exercise on brain cells

Some degree of cognitive decline—generally affecting thinking speed and attention span—is a normal part of aging. Research shows that age-related physical changes to certain areas of the brain, including the hippocampus and frontal and temporal lobes, may contribute to the issue. These changes are generally subtle, however, and don’t greatly affect quality of life. In fact, some areas of cognition, including vocabulary and verbal reasoning, may even improve as we get older.

Certain Nutrients Appear to Slow Brain Aging

Strokes, also known as cerebrovascular accidents, occur when something in the body causes a sudden blockage of blood flow to the brain. This sudden blockage also deprives the brain of oxygen. Strokes are rare in cats but are very serious and require immediate veterinary care. Although the chances of your...

Atrial fibrillation (AFib) and supraventricular tachycardia (SVT) are two heart conditions caused by atypical electrical activity in your heart. Supraventricular tachycardia (SVT) is an irregularly fast heartbeat in the lower chambers of your heart that’s caused by atypical electrical activity coming from above. “Supra” means “above,” and “ventricular” refers...

They might sound like health-conscious choices, but some products advertised as “sugar-free” could pose a health risk. A recent study by researchers from the Cleveland Clinic determined that xylitol — a type of sugar substitute known as a sugar alcohol — is associated with an increased risk of cardiovascular events like strokes and heart attacks.

Researchers have identified a key cellular process that helps the brain maintain its energy supply, potentially opening new avenues for treating cognitive decline and neurodegenerative diseases. The study, published in Nature, reveals how star-shaped brain cells called astrocytes detect and respond to the energy needs of nearby neurons. Led by...

Brain’s Energy Boost Mechanism Uncovered, Offers Hope for Late-Life Cognitive Health

As humans age, hematopoietic stem cells—the immature precursor cells that give rise to all blood and immune cells—accumulate mutations. Some of the mutations allow these stem cells to self-renew and expand more effectively than their non-mutated counterparts. This relatively poorly understood condition, known as clonal hematopoiesis of indeterminate potential (CHIP), is detectable in more than 10% of people older than 65 and is linked to increased risks of various inflammation-related diseases.
