Harmful proteins are also produced by glial cells. Memory loss, confusion, and speech difficulties are hallmark symptoms of Alzheimer’s disease, the leading cause of dementia, which currently affects around 35 million people globally, with numbers on the rise. Central to the disease is the naturally occurring brain protein, amyloid beta, which accumulates into insoluble clumps in affected individuals. These clumps form plaques between neurons, leading to neuronal damage.

Hidden Culprit Uncovered: New Research Reveals That Alzheimer’s Plaques Are Not Just a Neuronal Problem Anymore

A SINGLE-dose nasal spray treatment could 'wash away' build ups of toxic proteins associated with Alzheimer’s disease from brain cells and improve memory, scientists say. The study - performed on mice - paves the way for new treatments against Alzheimer's and dementia, researchers at the University of Texas Medical Branch said.

You’ve probably already heard of the ‘gut-brain axis’. It’s the biochemical signaling pathway between the gastrointestinal tract and your central nervous system, which has already been associated with bowel disease and dementia, as well as GERD and chronic headaches. It’s also why a good night’s sleep...

Q. My mother has atrial fibrillation. She takes a blood thinner to prevent stroke, but are there other risks she should know about?. A. Atrial fibrillation (also known as afib) is a common disorder marked by a rapid, irregular heart rhythm that causes blood to pool in the heart's upper chambers, or atria. The stagnant blood can form clots, which may then travel to the brain and cause a stroke. That's why people with afib take blood thinners, which don't actually "thin" the blood but rather discourage clot formation. While doctors have long warned about the heightened risk of stroke with afib, a recent study found that heart failure — when the heart fails to pump adequate amounts of blood to the body — might be a risk that occurs even more often.

Medically reviewed by Rafle Fernandez, MDMedically reviewed by Rafle Fernandez, MDAn enlarged heart (also known as cardiomegaly) isn't a condition on its own but is often an underlying sign of heart problems. Several conditions like coronary artery disease, high blood pressure, and kidney disease can cause an enlarged heart.Some people with an enlarged heart don't experience symptoms at all, but others may experience symptoms like trouble breathing, a racing heartbeat, and fluid build-up—all of which tend to worsen with physical exertion.

Among patients with fibromyalgia, there was a moderate negative correlation between vitamin D and physical functioning as well as between magnesium and stiffness. An exploratory study evaluating the link between specific micronutrients and the symptoms of fibromyalgia revealed vitamin D and magnesium played a role in physical function and stiffness among patients.1.

Irvine, Calif., Aug. 21, 2024 — Researchers from the University of California, Irvine have discovered the neurons responsible for “item memory,” deepening our understanding of how the brain stores and retrieves the details of “what” happened and offering a new target for treating Alzheimer’s disease.

About The Study: In this large-scale study, symptoms that characterized pediatric postacute sequelae of SARS-CoV-2 infection (PASC), or long COVID, differed by age group, and several distinct phenotypic PASC presentations were described. The research indices developed here will help researchers identify children and adolescents with high likelihood of PASC. Although these indices will require further research and validation, this work provides an important step toward a clinically useful tool for diagnosis with the ultimate goal of supporting optimal care for youth with PASC.

A bill quietly introduced this spring in the Colorado legislature to decriminalize the possession of drug paraphernalia obtained by harm reductionists has become law. As low-key as the legislation was introduced, the bill was signed into law without fanfare June 6. It garnered little to no media attention.

How did early humans use sharpened rocks to bring down megafauna 13,000 years ago? Did they throw spears tipped with carefully crafted, razor-sharp rocks called Clovis points? Did they surround and jab mammoths and mastadons? Or did they scavenge wounded animals, using Clovis points as a versatile tool to harvest meat and bones for food and supplies?

To kill mammoths in the Ice Age, people used planted pikes, not throwing spears, researchers say

An international team of scientists has uncovered a mechanism by which acute myeloid leukemia (AML) cells sustain their growth. Researchers at Baylor College of Medicine, University of Veterinary Medicine in Austria and Josep Carreras Leukemia Research Institute in Spain discovered that AML cells prevent the synthesis of proteins that suppress their growth by forcibly isolating the mRNAs that encode such proteins within structures known as P-bodies. These findings, published in Nature Cell Biology, offer a novel perspective into the survival mechanisms of AML and possibilities for new anti-cancer therapies.

In new research published in the scientific journal Discover Food, Dr. Asaf Tzachor, Founder and Academic Director of the Aviram Sustainability and Climate Program at Reichman University, along with a team of researchers from Iceland, Denmark and Austria, report the use of state-of-the-art biotechnology to cultivate photosynthetically-controlled Spirulina, and produce carbon–neutral and nutritious biomass containing unopposed, biologically active vitamin B12, in levels comparable to beef meat. This is the first time biologically active vitamin B12 has been reported in Spirulina.

Beta-blockers lower your heart rate and reduce your heart’s workload. If you have heart failure, they may help improve your cardiac function. Possible side effects include unusually slow heart rate and low blood pressure. Beta-blocker medications block the production of two stress hormones called epinephrine and norepinephrine. Doctors may...

In a study published today in Royal Society Open Science, researchers at the Marine Mammal Research Program (MMRP) at UH Hawaiʻi Institute of Marine Biology (HIMB) and Alaska Whale Foundation (AWF) consider a new designation of the humpback whales they study: tool wielders. Researchers have known that humpback whales create “bubble-nets” to hunt, but they have learned that the animals don’t just create the bubble-nets; they manipulate this unique tool in a variety of ways to maximize their food intake in Alaskan feeding grounds. This novel research demystifies a behavior key to the whales’ survival and offers a compelling case for including humpbacks among the rare animals that manufacture and wield their own tools.

Medically reviewed by Brigid Dwyer, MDMedically reviewed by Brigid Dwyer, MDDementia is a broad term that describes the loss of cognitive abilities like thinking, remembering, using language, and making decisions. Lewy body dementia (LBD) is one type of dementia, named after the scientist who discovered this variation. This type of dementia is thought to be caused by a buildup of a specific protein in the brain.  There are two types of LBD: dementia with Lewy bodies (DLB) and Parkinson’s disease dementia (PDD). In general, both types of LBD are caused by the same accumulation of protein in the brain and...

In addition to collecting more than 8,000 used needles in the past year from Denver drug users, the Harm Reduction Action Center passed out 10,000 meth pipes and “snort kits,” according to a newsletter sent to its supporters Thursday. They also connected about 1,700 people to medical, mental health and substance abuse treatment.
