Oct 21, 2024 | healthgrades.com | Katharine Lang

Alzheimer’s disease, the most common form of dementia, affects around 7 million people in the United States alone. It is a progressive disease that gradually affects memory, thinking and behavior, for which there is currently no cure. New research suggests that Alzheimer’s happens in two distinct stages: A slow phase with no symptoms, in which only a few vulnerable cell types are affected, followed by the destructive later phase, when the characteristic signs and symptoms of Alzheimer’s are seen.

Heart diseases raise dementia risk: Could a common blood thinner lower it?

Oct 16, 2024 | healthgrades.com | Paul Ian Cross

A new scientific statement from the American Heart Association (AHA) reveals a strong link between cardiovascular diseases — such as heart failure, atrial fibrillation and coronary heart disease — and an increased risk of cognitive impairment and dementia. The research explains how heart health directly impacts brain function, with conditions like high blood pressure and type 2 diabetes therefore contributing to cognitive decline.
Carbs or fats for breakfast? Which is best for healthy weight in men vs women?

Oct 15, 2024 | healthgrades.com | Robby Berman

A carbohydrate-rich breakfast for men and a fat-rich breakfast for women gets the day off to a good start, a new study suggests. While women store more fat than men, they also burn it faster to obtain energy, according to computer modeling used in the study. Metabolic differences between men and women have not been as fully studied due to research’s historically greater interest in men’s health.
Sleep, stress, and gut imbalances may impact colorectal cancer progression

Oct 13, 2024 | healthgrades.com | Hannah Flynn

Stress and working at night are both known to affect cancer risk, including colorectal cancer risk. Colorectal cancer risk and progression have both been linked to the microbiome, dysregulation of which has been linked to stress and disruption of the circadian rhythm.
GLP-1 drugs like Ozempic may protect brain health, several studies show

Oct 11, 2024 | healthgrades.com | Erika Watts

GLP-1 drugs such as Wegovy and Ozempic (semaglutide) and Zepbound (tirzepatide) may offer benefits that extend beyond aiding in weight loss in people who have type 2 diabetes or obesity. A new review takes a look at how GLP-1 drugs may offer neuroprotective benefits. Since obesity can cause chronic inflammation, including inflammation in the brain, it can also increase the risk of developing neurodegenerative diseases such as Alzheimer’s disease.

Brainstem damage could explain long COVID symptoms, precision MRI shows

Oct 10, 2024 | healthgrades.com | Tim Newman |Catarina Rua

Previous studies have shown that COVID-19 impacts brain health, but the details are still relatively mysterious. A new study takes a closer look using the latest scanning technology. The authors conclude that damage to the brainstem associated with infection may help explain some of the symptoms of long COVID. Following infection with SARS-CoV-2, the virus that causes COVID-19, some people experience long-term symptoms, including breathlessness and brain fog.
Toxic tau buildup tied to Alzheimer’s prevented by dual-targeting drug

Oct 10, 2024 | healthgrades.com | Paul Ian Cross

Scientists have developed a new drug that targets two key regions of the tau protein, a major contributor to Alzheimer’s disease. The drug, a peptide inhibitor called RI-AG03, successfully prevented the build-up of toxic tau proteins in both laboratory and fruit fly studies. Although further research is necessary, including clinical trials in humans, this research contributes to the advancement of more effective therapies for neurodegenerative diseases.
Mediterranean diet can help lower heart failure risk, particularly in women

Oct 9, 2024 | healthgrades.com | Jeanna Smiley

Heart failure is a major health issue associated with mortality and high healthcare costs. Overall heart failure prevalence is growing around the world, currently affecting 1% to 3% of the population. European researchers have found that adhering to the Mediterranean diet may help lower heart failure risk, especially for women. Women may have distinct risks for heart failure that following a Mediterranean diet could help lower.
