New York Times: Nearly One-Third of Covid-19 Patients in Study Had Altered Mental State. “Nearly a third of hospitalized Covid-19 patients experienced some type of altered mental function — ranging from confusion to delirium to unresponsiveness — in the largest study to date of neurological symptoms among coronavirus patients in an American hospital system.”
EurekAlert: Human Brain Project launches ‘Brain Matters’ webinar series. “The hour-long sessions will focus on different areas of brain research and feature expert speakers, with the goal of highlighting the HBP’s scientific achievements and the state-of-the-art services offered by its new infrastructure for brain research, EBRAINS.” The webinars are free and open to the public.
New York Times: How the Coronavirus Attacks the Brain. “A new study offers the first clear evidence that, in some people, the coronavirus invades brain cells, hijacking them to make copies of itself. The virus also seems to suck up all of the oxygen nearby, starving neighboring cells to death. It’s unclear how the virus gets to the brain or how often it sets off this trail of destruction. Infection of the brain is likely to be rare, but some people may be susceptible because of their genetic backgrounds, a high viral load or other reasons.”
El Pais: Over half of coronavirus patients in Spain have developed neurological problems, studies show. “The SARS-CoV-2 coronavirus attacks the respiratory system, but there is growing evidence that it also affects the nervous system. Several studies based on thousands of Spanish patients show that most of these individuals developed at least one neurological problem. This manifested itself in a wide range of symptoms, ranging from headaches to comatose states. In a percentage of cases, neurological conditions were even the principal cause of death. Although these symptoms have been attributed to the body’s excessive immune response to Covid-19, some research indicates that the virus is directly attacking the brain.”
STAT News: When Covid-19 hits the brain, it can cause strokes, psychosis and a dementia-like syndrome, new survey shows . “A new survey reveals a wide range of serious psychiatric and neurological complications tied to Covid-19 — including stroke, psychosis, and a dementia-like syndrome. The study underscores how aggressively the coronavirus can attack beyond the lungs, and the risk the disease can pose to younger adults.”
EurekAlert: Artificial intelligence enhances brain tumor diagnosis. “A new machine learning approach classifies a common type of brain tumour into low or high grades with almost 98% accuracy, researchers report in the journal IEEE Access. Scientists in India and Japan, including from Kyoto University’s Institute for Integrated Cell-Material Sciences (iCeMS), developed the method to help clinicians choose the most effective treatment strategy for individual patients.”
Financial Times, and not paywalled, at least for me: Coronavirus could infect human brain and replicate, US study shows. “US scientists have found the first direct evidence that coronavirus could infect the human brain and replicate inside its cells, heightening concern about the disease’s poorly understood neurological symptoms. Thomas Hartung and colleagues at Johns Hopkins University made the discovery after adding low levels of Sars-Cov-2, the virus responsible for Covid-19, to tiny neuronal balls known as mini-brains that are grown from human stem cells.”
Health Europa: AI collaboration creates largest brain haemorrhage image database. “The creation of the brain haemorrhage image database stems from the most recent edition of the Radiology Society of North America (RSNA) Artificial Intelligence (AI) Challenge. The two medical societies, RSNA and the American Society of Neuroradiology (ASNR), along with 60 volunteers, have created the collection that includes expertly annotated images.”
EurekAlert: ADDF launches over 200 in-depth Cognitive Vitality Reports . “The scientific reports, written by [Alzheimer’s Drug Discovery Foundation] neuroscientists, expand the Cognitive Vitality platform by making public a collection of in-depth analyses of drugs, drugs-in-development, supplements, nutraceuticals, food/drink, non-pharmacologic interventions, and risk factors related to brain health.”
Phys .org: Unveiling the biggest and most detailed map of the fly brain yet. “Janelia and Google scientists have constructed the most complete map of the fly brain ever created, pinpointing millions of connections between 25,000 neurons. Now, a wiring diagram of the entire brain is within reach.”
ScienceBlog: Mindfulness Video Game Changes Areas Of The Brain Associated With Attention. “A research team at the Center for Healthy Minds at the University of Wisconsin–Madison and the University of California, Irvine, designed a video game to improve mindfulness in middle schoolers and found that when young people played the game, they showed changes in areas of their brains that underlie attention.” Which is great, but the game is not yet publicly available.
Neowin: Increased screen-time might be impacting the physical structure of children’s brains. “The increasing usage and integration of smartphones in our lives, and those of our children, in particular, has often garnered criticism from many. As such, people have been wary about the potential downsides of the rampancy and what it entails. And one study probes into this issue.”
ZDNet: AI can now read the thoughts of paralysed patients as they imagine they are writing. “Handwriting is becoming a rare skill in the digital age. But researchers have now discovered a new application that could significantly improve the way tetraplegic people, who are often also unable to speak, communicate with the outside world.”
Neowin: Neural network system has achieved remarkable accuracy in detecting brain hemorrhages. “Deep learning and its applications have grown in recent years. Recently, researchers from ETH Zurich used the technique to study dark matter in an industry first. Now, a team working with the University of California, Berkeley and the University of California, San Francisco (UCSF) School of Medicine have trained a convolutional neural network dubbed ‘PatchFCN’ that detects brain hemorrhages with remarkable accuracy.”
Spectrum: Decades-old collection of monkey brain tissue goes virtual. “The material comes from Pasko Rakic and the late Patricia Goldman-Rakic, who began studying brain development in macaques more than 50 years ago. Their original collection contains roughly 300 brains. About 10,000 slides from 185 of these sectioned specimens have been digitized so far, says Alvaro Duque, a research scientist in neuroscience at Yale University.”
