Stroke News and Research

RSS

A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.

Lockdowns improved air quality, averted tens of thousands of deaths in severely polluted regions

Lockdowns initiated to curb the spread of the coronavirus in China and Europe at the beginning of the pandemic improved air quality, averting tens of thousands of deaths in regions where air pollution has a significant impact on mortality, a new study shows.

Maltreatment at early age affects girls more than boys

New research by a University of Georgia scientist reveals that girls who are maltreated show higher levels of inflammation at an early age than boys who are maltreated or children who have not experienced abuse. This finding may forecast chronic mental and physical health problems in midlife.

SARS-CoV-2 infection of carotid arteries may explain vascular involvement in COVID-19

A new study published on the preprint server bioRxiv in October 2020 shows that the virus causing COVID-19, namely, SARS-CoV-2, produces replicative infection in the carotid arteries and affects the vascular responses. This could have a profound bearing on the understanding of the disease and its clinical treatment.

Sleep disorders common during COVID-19 pandemic

A recent study published on the preprint server medRxiv* in October 2020 reveals the significant prevalence of sleep abnormalities among the population in areas affected by COVID-19. This is likely to cause a heavy toll on mental and physical health if sustained over the long run.

COVID-19 causes potentially damaging neurological injuries, study shows

Without directly invading the brain or nerves, the virus responsible for COVID-19 causes potentially damaging neurological injuries in about one in seven infected, a new study shows.

Research shows 10 or more medications are prescribed to older heart failure patients

More than half of older patients hospitalized for heart failure, a progressive condition in which the heart doesn't pump blood as well as it should, are discharged from the hospital with prescriptions for 10 or more medications, according to new research published today in Circulation: Heart Failure, an American Heart Association journal.

Study: Deaths recorded during pandemic is higher than those attributed to COVID-19

For every two deaths attributed to COVID-19 in the U.S., a third American dies as a result of the pandemic, according to new data publishing Oct. 12 in the Journal of the American Medical Association.

Scientists explain why some COVID-19 patients develop neurological symptoms

Now, a new study published on the preprint server bioRxiv sheds light on the mechanism behind brain involvement in the COVID-19 pandemic. A team of researchers at the Krembil Research Institute and the University of Toronto in Canada aimed to understand further the potential mechanisms underlying SARS-CoV-2 tropism for brain vasculature to see how infection occurs in the brain.

Enzyme SSH1 impairs the disposal of damaged tau and neurotoxic mitochondria

In a healthy brain, the multistep waste clearance process known as autophagy routinely removes and degrades damaged cell components - including malformed proteins like tau and toxic mitochondria.

Two well-known neurochemicals found to be involved in sub-second perception, cognition

In first-of-their-kind observations in the human brain, an international team of researchers has revealed two well-known neurochemicals - dopamine and serotonin - are at work at sub-second speeds to shape how people perceive the world and take action based on their perception.

Dopamine and serotonin play role in perception and decision-making

Scientists at Wake Forest School of Medicine have recorded real time changes in dopamine and serotonin levels in the human brain that are involved with perception and decision-making.

Elevated plasma ACE2 activity persists months after SARS-CoV-2 infection

Recently, researchers from the University of Melbourne and Immune Therapies Group, Burnet Institute, Melbourne, reported that downregulation of cardiac ACE2 is linked to increased plasma ACE2 activity. This study is summarized in a preprint paper published in medRxiv.

Pathways contributing to hypercoagulability in severe SARS‐CoV‐2 patients

In a study by researchers explored the possible mechanisms of the clotting disorder, focusing on the role of hypoxia-related activation of coagulation factors; cytokine storm, activation of neutrophils, and the release of neutrophil extracellular traps.

WVU receives $1.2 million to bring telehealth capabilities to rural emergency departments

Rural emergency departments often lack the medical specialists who staff larger, urban hospitals. Yet rural patients have the same conditions--and need the same prompt care--that people in cities do.

Higher HMBGB1 levels associated with obesity, inflammation, and cardiovascular disease in younger black adults

A "danger molecule" is higher in the blood of younger black adults than whites, females than males and increases with weight and age, researchers report in the first large, longitudinal study associating circulating HMGB1 levels with obesity, inflammation promoters and early indicators of cardiovascular risk in humans.
