The studies are out there and so is the real-life evidence, yet their messages of the dangers of concussion are being ignored, say authors of a new study: high school athletes are still sustaining brain injuries and in increasing numbers. These researchers also found that young athletes who get concussions need at least a month to recover. The new was
A significant number of patients reported a deterioration in their hearing when questioned eight weeks after discharge from a hospital admission for COVID-19, according to University of Manchester audiologists, in a study supported by the NIHR Manchester Biomedical Research Centre (BRC). One hundred and twenty-one of the adults admitted to Wythenshawe Hospital, part of University
As a person’s weight goes up, all regions of the brain go down in activity and blood flow, according to a new brain imaging study in the Journal of Alzheimer’s Disease. One of the largest studies linking obesity with brain dysfunction, scientists analyzed over 35,000 functional neuroimaging scans using single-photon emission computerized tomography (SPECT) from more
Health experts believe keeping your body active usually means good things from your brain too. You might think having a job with lots of physical activity keeps you sharper than sitting in an office all day, but a new study finds the opposite is often true. Researchers say tests on office workers reveal their brain
New research by neuroscientists at the University of Pittsburgh and University of California San Francisco (UCSF) revealed that a simple, earbud-like device developed at UCSF that imperceptibly stimulates a key nerve leading to the brain could significantly improve the wearer’s ability to learn the sounds of a new language. This device may have wide-ranging applications
Flu (influenza) and pneumonia vaccinations are associated with reduced risk of Alzheimer’s disease, according to new research reported at the Alzheimer’s Association International Conference 2020. Being vaccinated against influenza was associated with a 17% reduction in Alzheimer’s incidence. Pneumonia vaccinations given between the ages of 65 and 75, reduced Alzheimer’s risk by up to 40%.
Study reveals mutations of SARS-CoV-2, the virus that causes COVID-19, may not be a random process, but instead, humans are mutating it as part of a defense mechanism to degrade the virus, but natural selection of the virus enables it to bounce back. The findings could help in the design of vaccines against the virus.
Blood samples taken from people enrolled in an Alzheimer’s research study revealed higher levels of phosphorylated tau 217 that correlated with the presence of amyloid plaques. People with amyloid in their brains had up to three times more of the tau protein in their blood than those who had no evidence of amyloid accumulation. The
Experts from online pharmacy reported increasing of penis size can cause health issues Botox, a medication derived from a bacterial toxin, is commonly injected to ease wrinkles, migraines, muscle spasms, excessive sweating and incontinence. Forehead injection of the medication is also currently being tested in clinical trials for its ability to treat depression. Researchers at Skaggs School of Pharmacy and Pharmaceutical Sciences at University of California San Diego
A series of autopsies conducted by LSU Health New Orleans pathologists shows the damage to the hearts of COVID-19 patients is not the expected typical inflammation of the heart muscle associated with myocarditis, but rather a unique pattern of cell death in scattered individual heart muscle cells. They report the findings of a detailed study
Pupillary response in those with PTSD differs from people who have not experienced traumatic events. The pupils of those with PTSD failed to show sharp constriction caused by light changes, and more enlargement when exposed to emotional stimuli that other participants. Patients with PTSD not only showed an exaggerated response to threatening stimuli but also
As the SARS-CoV-2 virus, or COVID-19 has unfurled its tentacles across the globe, the severe respiratory and pulmonary disorders associated with the infection have become well known. However, recent case studies also have strongly suggested the presence of cerebrovascular-neurological dysfunction in COVID-19 patients, including large artery ischemic strokes that originate in one of the brain’s
Neurofilament light chain as a blood biomarker can detect brain injury and predict recovery in different groups, including professional hockey players with acute or chronic concussions, according to a study published in Neurology. Traumatic brain injury is a leading cause of death and disability in the US, with more than 2.87 million emergency department visits, hospitalizations, and deaths
Early use of cannabis affects the working memory of adolescents, but its deleterious effect is more pronounced in girls, posing a risk to their academic success as well as to their memory when they reach adulthood. These are the findings of a study conducted by Sima Noorbakhsh of the CHU Sainte-Justine Research Centre, under the
Older women who eat more than one to two servings a week of baked or broiled fish or shellfish may consume enough omega-3 fatty acids to counteract the effects of air pollution on the brain, according to a new study published in the July 15, 2020 edition of Neurology. Researchers found that among older women who
Genes linked to aging that could help explain why some people age at different rates to others have been identified by scientists. The international study using genetic data from more than a million people suggests that maintaining healthy levels of iron in the blood could be a key to aging better and living longer. The
Depressed mood or anxiety exhibited in COVID-19 patients may possibly be a sign the virus affects the central nervous system, according to an international study led by a University of Cincinnati College of Medicine researcher. These two psychological symptoms were most closely associated with a loss of smell and taste rather than the more severe
Scientists from Trinity College Dublin have discovered a new link between impaired brain energy metabolism and delirium – a disorienting and distressing disorder particularly common in the elderly and one that is currently occurring in a large proportion of patients hospitalised with COVID-19. While much of the research was conducted in mice, additional work suggests
Data presented by researchers from GliaLab at the Letten Centre at the University of Oslo lends further support that astrocytes are important to assure proper slow wave sleep. This finding that a non-neuronal cell type is crucial for appropriate slow wave sleep will guide future studies aimed at deciphering the mechanisms of and identifying novel
Researchers at Center for BrainHealth, part of The University of Texas at Dallas, recently examined underlying brain networks in long-term cannabis users to identify patterns of brain connectivity when the users crave or have a desire to consume cannabis. While regional brain activation and static connectivity in response to cravings have been studied before, fluctuations
