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.

Study highlights the neurologic manifestations linked with COVID-19 in hospitalized children

Of hospitalized children who tested or were presumed positive for SARS-CoV-2, 44% developed neurological symptoms, and these kids were more likely to require intensive care than their peers who didn't experience such symptoms, according to a new study led by a pediatrician-scientist at UPMC and the University of Pittsburgh School of Medicine.

Experts highlight the neurological effects of SARS-CoV-2 and the need for rigorous research

SARS-CoV-2 was initially identified as a respiratory virus, but it can affect the entire body, including the nervous system.

Northwestern medical student explores trends in pre-pregnancy cardiovascular health

After completing a hospital shadowing experience at while an undergraduate student at Yale University, Michael Wang knew that he wanted to pursue medicine as a career path. Now a fourth-year medical student at Northwestern University Feinberg School of Medicine, Wang is currently applying to internal medicine residency programs with a focus in primary care.

New compact and affordable device for recording brain activity

Scientists from Skoltech, South Ural State University, and elsewhere have developed a device for recording brain activity that is more compact and affordable than the solutions currently on the market.

Treatment with immune-boosting protein and radiation improves survival in mice with glioblastoma

Glioblastoma, an aggressive cancer in the brain or spinal cord, has proven stubbornly resistant to newer immunotherapies. And radiation and chemotherapy, the standard treatment for glioblastoma, result in fewer than 10% of patients surviving longer than five years after diagnosis.

Novel robotic replica of human spine enables surgeons to preview the effects of surgery

Degenerative disc disease affects about 40 percent of people aged 40, increasing to about 80 percent among those aged 80 or older. The disease, which is the deterioration of one or more intervertebral discs of the spine, often is surgically treated with cervical disc implants.

Scientists reveal toxic astrocyte changes in ALS

Scientists at the Francis Crick Institute have revealed harmful changes in supporting cells, called astrocytes, in Amyotrophic Lateral Sclerosis (ALS) in two publications in Brain and Genome Research.

Study shows inequalities in addressing post-acute neurological manifestations of COVID-19

Researchers have explored the inequities in understanding and addressing the neurological complications of COVID-19 among marginalized communities in the United States.

Study provides insights into how SARS-CoV-2 impacts the brain

Some patients who develop new cognitive symptoms after a mild bout of COVID have abnormalities in their cerebrospinal fluid similar to those found in people with other infectious diseases.

Risk factors affect cardiovascular disease risk even in patients with no coronary artery calcium

Among patients with no detectable coronary artery calcium, those who smoke, have diabetes or hypertension nonetheless have the highest risk of cardiovascular disease events, according to a study published in the journal Circulation.

Protein biomarkers in urine could be used to diagnose concussion and monitor recovery

Concussion can be frustratingly hard to diagnose and track. The injury doesn't show up on routine brain scans, and there is no definitive diagnostic test. It's usually diagnosed based on symptoms, and, in athletes, comparison with baseline testing if it was done. But concussion symptoms are non-specific, unreliable, and easily influenced by emotions.

Genome editing in vascular endothelial cells made possible with a powerful new delivery system

Northwestern Medicine scientists developed a unique nanoparticle to deliver genome editing technology, including CRISPR/Cas9, to endothelial cells, which line blood vessel walls.

Research shows fewer deaths related to COVID-19 in Cape Town during fourth wave

Researchers observe changes in COVID-19-related deaths during the fourth wave of the COVID-19 pandemic in South Africa.

Multiple sclerosis may be caused by infection with the Epstein-Barr virus

Multiple sclerosis (MS), a progressive disease that affects 2.8 million people worldwide and for which there is no definitive cure, is likely caused by infection with the Epstein-Barr virus (EBV), according to a study led by Harvard T.H. Chan School of Public Health researchers.

Telemedicine at Johns Hopkins Medicine enables a stroke patient to be treated with high level of care

A patient believed to have suffered a stroke typically gets transported to the nearest emergency room for tests to determine the best course of action. Telemedicine at Johns Hopkins Medicine enabled one patient to have her stroke diagnosed and a treatment plan set up without ever stepping foot in a hospital.

Decoding imagined language to treat people suffering from aphasia

What if it were possible to decode the internal language of individuals deprived of the ability to express themselves? This is the objective of a team of neuroscientists from the University of Geneva (UNIGE) and the University Hospitals of Geneva.

Study finds a subset of vascular macrophages to be powerful ally in the fight against atherosclerosis

A new study reveals the existence of a powerful ally in the fight against cardiovascular disease, a protective subset of vascular macrophages expressing the C-type lectin receptor CLEC4A2, a molecule which fosters "good" macrophage behavior within the vessel wall.

Adding a tomato concentrate to the diet can reduce intestinal inflammation related to HIV

New UCLA-led research in mice suggests that adding a certain type of tomato concentrate to the diet can reduce the intestinal inflammation that is associated with HIV. Left untreated, intestinal inflammation can accelerate arterial disease, which in turn can lead to heart attack and stroke.

Breastfeeding linked to reduced cardiovascular disease risk in mothers

Women who breastfed were less likely to develop heart disease or a stroke, or die from cardiovascular disease than women who did not breastfeed, according to a meta-analysis published today in a pregnancy spotlight issue of the Journal of the American Heart Association (JAHA), an open access, peer-reviewed journal of the American Heart Association.
