stroke

Acute stroke, also known as a “brain attack,” is a medical emergency that occurs when the blood flow to the brain is interrupted or reduced, leading to damage or death of brain cells. This can happen as a result of a blocked artery, a ruptured blood vessel, or a clot that travels to the brain.New research from the University of Galway, published in the Journal of the American Medical Association Network Open (<span class="glossaryLink" aria-describedby="tt" data-cmtooltip="<div…

A nurses fills up syringes for patients as they receive their coronavirus disease (COVID-19) booster vaccination during a Pfizer-BioNTech vaccination clinic in Southfield, Michigan, September 29, 2021.Emily Elconin | ReutersThe Food and Drug Administration hasn't found an increased risk of stroke for seniors who've received Pfizer's omicron booster shot, a federal health official said Thursday.The FDA launched an extensive review of federal data after investigators at the Centers for Disease Control and Prevention…

Stroke patients in the US could soon take advantage of cutting-edge robotics during the recovery process. The Food and Drug Administration has cleared Wandercraft's Atalante exoskeleton for use in stroke rehabilitation. The machine can help with intensive gait training, particularly for people with limited upper body mobility that might prevent using other methods. The current-generation Atalante is a self-balancing, battery-powered device with an adjustable gait that can help with early steps through to more natural…

The Centers for Disease Control and Prevention on Friday said it is "very unlikely" the Pfizer omicron booster carries a risk of stroke for seniors after it launched an investigation into a preliminary safety concern detected by one of its monitoring systems.The CDC, in a statement posted to its website Friday, said a surveillance system called the Vaccine Safety Datalink detected a possible risk for stroke in people ages 65 and older who received the Pfizer booster shot targeting the omicron Covid variant. A CDC…

ANI Washington, January 3 Air pollution has been widely associated with an increased risk of stroke. A new study looks at the role of air pollution on the trajectory of stroke, including cardiovascular events after first stroke and death. The study is published in the September 28, 2022, online issue of Neurology, the medical journal of the American Academy of Neurology. “We found that high levels of air pollution were associated with increased risks of transitions from…

People with one of the type A blood groups appear to be more likely to have a stroke before the age of 60 compared with people with other blood types, according to a 2022 study.Blood types describe the rich variety of chemicals displayed on the surface of our red blood cells. Among the most familiar are those named A and B, which can be present together as AB, individually as A or B, or not present at all, as O.Even within these major blood types, there are subtle variations arising from mutations in the genes…

Scientists at the University of Colorado Anschutz Medical Campus believe they have discovered how a common disease called shingles can increase a person's risk of stroke. The novel findings reveal how latent viral infections can be reawakened after lying dormant for years and cause health issues beyond a mild acute disease.Most people are infected with varicella-zoster virus (VZV) in childhood, and for some it can lead to a disease known as chickenpox. Despite most signs of the illness quickly resolving in many people the…

Over 90 percent of the world population has the virus that causes chickenpox lying dormant in their nervous system. Most people contract the varicella zoster virus, or VZV, when they get chickenpox as children.For around a third of these people, this same virus will reactivate years later and cause shingles, also called herpes zoster.While most people are familiar with the painful rash that VZV causes for shingles, a wide spectrum of other complications can also occur even without visible skin symptoms.Among the most…

Shingles is a disease that causes a painful rash.Researchers discover a potential explanation for why those who have had shingles are more likely to suffer a stroke.According to recent research from the University of Colorado Anschutz Medical Campus, scientists looking into why people who have had shingles are at a higher risk of stroke now believe the answer lies within lipid vesicles called exosomes that transport proteins and genetic information between cells.The study explores the mechanisms behind the connection…
