Women are about twice as likely as men to be diagnosed with Alzheimer’s disease. Some of that is age; in the U.S., women outlive men by five to six years, and advanced age is the strongest risk factor for Alzheimer’s. But there’s more to it than that, so Alzheimer’s researchers continue to look for other […]
Three years ago, an international study commissioned by the journal Lancet listed 12 modifiable factors that increased the risk of dementia, including three new ones: excessive alcohol, head injury and air pollution. Writing in the May 2, 2023 issue of the Journal of Alzheimer’s Disease, a team of researchers, led by scientists at University of […]
A new study published today reveals an association between poor air quality in India and impaired cognition in infants under two. Lead researcher Prof John Spencer, from UEA’s School of Psychology, said: “Prior work has shown that poor air quality is linked to cognitive deficits in children, as well as to emotional and behavioral problems, […]
How do you build complex structures for housing cells using a material as soft as jelly? Rice University scientists have the answer, and it represents a potential leap forward for regenerative medicine and medical research in general. Researchers in the lab of Rice’s Jeffrey Hartgerink have figured out how to 3D-print the well-defined structures using […]
Anticoagulants, or blood thinners, break down and prevent blood clots, semi-solid clumps of blood cells, and other substances that can block blood flow. However, anticoagulants can do their job too well, preventing clotting altogether and resulting in excessive external or internal bleeding. A new study from researchers at the University of British Columbia (UBC) and […]
Fast but sloppy, that’s how the transcription of genes changes with age. Six research groups discovered a new molecular mechanism that contributes to aging by studying the transcription process in five different model organisms and in a wide variety of tissues. Aging impairs a wide range of cellular processes. Among these processes, the reading of […]
In hopes of making it easier to deliver drugs through the skin, MIT researchers have developed a wearable patch that applies painless ultrasonic waves to the skin, creating tiny channels that drugs can pass through. “The ease-of-use and high-repeatability offered by this system provides a game-changing alternative to patients and consumers suffering from skin conditions […]
Researchers have established that biological sex plays a role in determining an individual’s risk of brain disorders. For example, boys are more likely to be diagnosed with behavioral conditions like autism or attention deficit disorder, whereas women are more likely to suffer from anxiety disorders, depression, or migraines. However, experts do not fully understand how […]
People who have low bone density may have an increased risk of developing dementia compared to people who have higher bone density, according to a study. “Low bone density and dementia are two conditions that commonly affect older people simultaneously, especially as bone loss often increases due to physical inactivity and poor nutrition during dementia,” […]
To get therapies into the brain after a stroke, researchers are increasingly making use of the blood-brain barrier, which allows only certain molecules to pass from the blood into the brain. Current stroke therapies are only effective if they are delivered within a short window of time, which limits their effectiveness in many patients.Many new […]
