Parkinson’s disease usually is thought of as a movement disorder. People with Parkinson’s typically first develop a tremor in one hand, followed by slowed movement, stiffness and loss of balance. But within 10 years of diagnosis, more than three-quarters of Parkinson’s patients also develop cognitive problems such as difficulty with memory and with performing sequential

Researchers at ETH Zurich have developed a method for concentrating and releasing drugs in the brain with pinpoint accuracy. This could make it possible in the future to deliver psychiatric and cancer drugs and other medications only to those regions of the brain where this is medically desirable. Today, this is practically impossible—drugs traveling through

Iowa woman in her 40s with a skull defect started leaking BRAIN FLUID out of her nose after getting a swab test for COVID-19 A woman in her 40s got tested for COVID-19 before undergoing a hernia surgery Soon after the test, clear fluid started running from her nose, she got nauseous, vomited and developed head and

A research team led by Professor Takumi Toru of Kobe University’s Graduate School of Medicine (also a Senior Visiting Scientist at RIKEN Center for Biosystems Dynamics Research) have identified ‘social cells’ in the brain that are related to social behavior. The cells were identified via Ca imaging conducted using a microendoscope. It is expected that

Prolonged sleep deprivation can lead to severe health problems in humans and other animals. But why is sleep so vital to our health? A UCLA-led team of scientists has answered this question and shown for the first time that a dramatic change in the purpose of sleep occurs at the age of about 2-and-a-half. Before

Obesity in expectant mothers may hinder the development of the babies’ brains as early as the second trimester, a new study finds. Led by researchers at NYU Grossman School of Medicine, the investigation linked high body mass index (BMI), an indicator of obesity, to changes in two brain areas, the prefrontal cortex and anterior insula.

Dozens of molecules may tangle up with rogue bundles of tau, a protein that normally gives nerve fibers structure, to cause brain cell damage that contributes to neurodegenerative diseases, a new study shows. Neuroscientists have previously found that tau can become toxic when extra chemical molecules accumulate with its structure in the brain, causing it

A first-in-human study presented at the Society of Nuclear Medicine and Molecular Imaging 2020 Annual Meeting has demonstrated the safety, favorable pharmacokinetic and dosimetry profile of 64Cu-EBRGD, a new, relatively long-lived PET tracer, in patients with glioblastomas. The radiotracer proved to be a superior, high-contrast imaging diagnostic in patients, visualizing tumors that express low or

Science is collaborative by nature, since scientific knowledge only advances, step by step, through combined efforts and findings. Nevertheless, there is often a lack of communication regarding the more technical and everyday advances in laboratory work, and as a result, research progresses less quickly. In recent years, the development of the digital ecosystem has resulted

An innovative use of focused ultrasound being pioneered at the University of Virginia School of Medicine is showing promise against glioblastoma, the deadliest brain tumor, and could prove useful against other difficult-to-treat cancers. The technique hits cancer cells with a drug that sensitizes them to sound waves, then blasts them with focused ultrasound. The sound

Researchers at Beijing Normal university and Leiden University have recently carried out a study investigating patterns in neural activity that could be observed in humans during intergroup conflicts (i.e., conflicts between different groups of individuals). Their paper, published in Nature Neuroscience, draws inspiration from “The crowd: A study of the popular mind,” a book by

A protein shredder that occurs in cell membranes of brain cells apparently also indirectly regulates the fat metabolism. This is shown by a recent study by the University of Bonn. The shredder, known as gamma-secretase, is considered a possible target for drugs against cancer and Alzheimer’s disease. However, the results suggest that such agents may

How much we value an item is often related to what other people have. You might want the newest fashion, but not once everybody has it. Or, winning a free lunch at your favorite restaurant might not seem as great if the other person won a million dollars. Now, researchers in Japan have discovered a

Each day, humans and animals rely on habits to complete routine tasks such as eating and sleeping. As new habits are formed, this enables us to do things automatically without thinking. As the brain starts to develop a new habit, in as little as a half a second, one region of the brain, the dorsolateral

The human-made chemicals that make our kitchen pans stick-free, our athletic wear water-repellent and firefighting chemicals more efficient do their jobs incredibly well, but it’s at the expense of lingering in the body and environment for what is believed to be forever. These forever chemicals, perfluorooctane sulfonate and perfluorooctanoic acid, more commonly known as PFOS

(HealthDay)—Many mothers-to-be feel overwhelmed by stress, and it might have implications for their babies’ brain development in the womb, a new study suggests. The researchers found that even in a group of highly educated, healthy pregnant women, stress and anxiety were common. More than one-quarter reported higher-than-average levels of “perceived stress,” while a similar number

Baby born with a tiny head and part of his BRAIN sticking out from his misshapen skull defies slim chance of survival to reach his first birthday Ozzie Gordon’s birth defect causes his brain and skull to form incorrectly  His brain bulged outside of his skull, which was later fixed with surgery  Parents Omobola and

Brain imaging may one day be used to help diagnose mental health disorders—including depression and anxiety—with greater accuracy, according to a new study conducted in a large sample of youth at the University of Pennsylvania and led by Antonia Kaczkurkin, Ph.D. and Theodore Satterthwaite, MD. And knowing more about the neurobiology behind psychiatric disorders could

Zika virus infection can stunt neonatal brain development, a condition known as microcephaly, in which babies are born with abnormally small heads. To determine how best to prevent and treat the viral infection, scientists first need to understand how the pathogen gets inside brain cells. Employing different approaches to answer different questions, two research teams

English and Italian speakers with dementia-related language impairment experience distinct kinds of speech and reading difficulties based on features of their native languages, according to new research by scientists at the UC San Francisco Memory and Aging Center and colleagues at the Neuroimaging Research Unit and Neurology Unit at the San Raffaele Scientific Institute in
