Sound waves at frequencies above the threshold for human hearing are routinely used in medical care. Also known as ultrasound, these sound waves can help clinicians diagnose and monitor disease, and can also provide first glimpses of your newest family members. And now, patients with conditions ranging from cancer to neurodegenerative diseases like Alzheimer’s may soon benefit from recent advances …

The authors suggest this means that age-related brain changes do not explain …

Scientists have repaired a natural gateway into the brains of mice, allowing the clumps and tangles associated with Alzheimer’s disease to be swept away. After just three drug injections, mice with certain genes that mimic Alzheimer’s showed a reversal of several key pathological features. Within hours of the first injection, the animal brains showed a nearly 45 percent reduction in …

Scientists at the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have created a pioneering brain imaging method that captures how the brain’s smallest blood vessels pulse in time with each heartbeat. These subtle movements may offer vital insights into aging and conditions such as Alzheimer’s disease. Published in Nature …

NEWYou can now listen to Fox News articles! A Washington man appeared to be destined to develop Alzheimer’s disease — but against all genetic odds, he has eluded the common dementia for decades. Researchers at the Washington University School of Medicine in St. Louis recently published a study focusing on Doug Whitney, 76, who lives near Seattle. He has a …

The US Food and Drug Administration has given clearance to another blood test to help assess Alzheimer’s disease and other causes of cognitive decline, providing a broader understanding of when the disease can be ruled out. Roche Diagnostics said Monday that its Elecsys pTau181 test, developed in collaboration with Eli Lilly, could be used by primary care physicians to help …

Scientists have developed a nanoparticle-based treatment that successfully reversed Alzheimer’s disease in mice. As detailed in a new paper published in the journal Signal Transduction and Targeted Therapy, the team co-led by the Institute for Bioengineering of Catalonia, Spain (IBEC), and West China Hospital, Sichuan University, developed bioactive “supramolecular drugs” that can proactively repair the blood-brain barrier. The barrier plays …

The pursuit of a cure for Alzheimer’s disease is becoming an increasingly competitive and contentious quest, with recent years witnessing several important controversies. In July 2022, Science magazine reported that a key 2006 research paper, published in the prestigious journal Nature, which identified a subtype of brain protein called beta-amyloid as the cause of Alzheimer’s, may have been based on …
