Stroke News and Research

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.

Adding antiplatelet therapy to oral anticoagulants raises risk for TAVR patients with atrial fibrillation

Patients with atrial fibrillation who took oral anticoagulants alone after undergoing transcatheter aortic valve replacement had a lower rate of bleeding complications without an increased risk of clotting-related complications compared to patients who took antiplatelet medication in addition to oral anticoagulants, in a trial presented at the American College of Cardiology's Annual Scientific Session Together with World Congress of Cardiology.

Newly developed laboratory model helps reveal how HIV infection affects the brain

Though many negative repercussions of human immunodeficiency virus infection can be mitigated with the use of antiretroviral therapy, one area where medical advances haven't made as much progress is in the reduction of cognitive impacts.

Lessons from the Spanish flu: Strict and early isolation really effective in minimizing disease spread

Large events are canceled, restaurants and non-essential businesses are closed, and in many states, residents have been asked to shelter in place, all to limit the spread and impact of the COVID-19 virus.

Removing a gene prevents Type 1 diabetes in mice by disguising beta cells

Removing a gene from the cells that produce insulin prevents mice from developing Type 1 diabetes by sparing the cells an attack from their own immune system, a new UW-Madison study shows.

Deleting a gene prevents Type 1 diabetes in mice by disguising insulin-producing cells

Scientists have innovated a potential method of preventing Type 1 diabetes in those at high risk.

Excessive salt intake weakens the immune system

A high-salt diet is not only bad for one's blood pressure, but also for the immune system. This is the conclusion of a current study under the leadership of the University Hospital Bonn.

Having a bath regularly reduces risk of cardiovascular disease

A new study, published online in the journal Heart in March 2020, reports that with hot water, it seems to be a case of washing away health problems – literally. As a result, the more a person uses hot tubs, the better in terms of cardiovascular health. In other words, soaking in hot water daily improves heart health more than having a hot tub once or twice a day.

Researchers propose a stopgap measure to help Covid-19 patients in respiratory distress

Researchers at MIT and the University of Colorado at Denver have proposed a stopgap measure that they believe could help Covid-19 patients who are in acute respiratory distress.

Bedtime deviations may affect cardiovascular health

Despite increasing awareness of how critical sleep is to our health, getting a good night's rest remains increasingly difficult in a world that's always "on" - responding to emails at all hours, news cycles that change with every tweet and staring endlessly into the blue light of cell phone, tablet and computers screens.

Drebrin autoantibodies trigger epilepsy

Certain forms of epilepsy are accompanied by inflammation of important brain regions. Researchers at the University of Bonn have now identified a mechanism that explains this link.

Early evaluation of stroke victims can help link brain regions to speech functions

New research from Rice University and Baylor College of Medicine shows analyzing the brains of stroke victims just days after the stroke allows researchers to link various speech functions to different parts of the brain, an important breakthrough that may lead to better treatment and recovery.

Study unravels brain mechanisms in the event of a second stroke

It is now widely known that the brain is much more malleable than once thought. Even after stroke or brain injury the brain often succeeds finding a new balance between the failed regions and the functions they serve.

High-speed microscope records the passage of millisecond electrical pulses through neurons

Electrical and chemical signals flash through our brains constantly as we move through the world, but it would take a high-speed camera and a window into the brain to capture their fleeting paths.

Research provides better understanding of how tremor happens

Researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Research Institute at Texas Children's Hospital have improved our understanding of how tremor -- the most common movement disorder -- happens, opening the possibility of novel therapies for this condition.
