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.

Air pollution, dementia, and cardiovascular disease

A new study published in March 2020 in the journal JAMA Neurology shows an association between air pollution and the development of dementia. However, the role played by cardiovascular disease (CVD) is yet to become apparent.

Scientists identify new biomarker to detect subclinical atherosclerosis

Scientists at the Centro Nacional de Investigaciones Cardiovasculares and the Instituto de Investigación Sanitaria-Fundación Jiménez Díaz in Madrid have demonstrated that a proteins present in early atheroma plaques--accumulations of cholesterol in the wall of arteries--could be used as a biomarker to detect atherosclerosis in the subclinical phase, before the appearance of symptoms.

Researchers use brain-computer interfaces technology to decode the brain’s mechanism

When people suffer debilitating injuries or illnesses of the nervous system, they sometimes lose the ability to perform tasks normally taken for granted, such as walking, playing music or driving a car. They can imagine doing something, but the injury might block that action from occurring.

Study adds increasing evidence that autoimmunity plays a role in Parkinson's disease

A new study co-led by scientists at the La Jolla Institute for Immunology adds increasing evidence that Parkinson's disease is partly an autoimmune disease. In fact, the researchers report that signs of autoimmunity can appear in Parkinson's disease patients years before their official diagnosis.

ACC issues guidance to encourage heart attack, stroke patients to seek medical help

Through its CardioSmart patient initiative, the American College of Cardiology has issued guidance to encourage patients experiencing a heart attack or stroke to call 911.

Are overactive immune cells causing COVID-19-related deaths?

While the COVID-19 pandemic is devastating many regions, the world over, a new paper published in the Journal of Experimental Medicine in April 2020 describes the possibility that the critical or very severe cases of COVID-19 are due to the production of neutrophil extracellular traps (NET) due to hyperactivated immune cells.

Pregnancy and fetal outcomes with COVID-19

A new study published preprint in the non-peer-reviewed journal medRxiv in April 2020 provides a systematic review of maternal and fetal outcomes in pregnancy affected by COVID-19, as well as the risk of vertical transmission of the virus.

Trial to evaluate how blood pressure medications affect outcomes among COVID-19 patients

A new trial led by the Perelman School of Medicine at the University of Pennsylvania will evaluate whether the use of medications to treat high blood pressure affect outcomes among patients who are prescribed the medication and hospitalized with COVID-19.

Study reveals molecular causes of brain asymmetry

Scientists may have solved one of the most puzzling and persistent mysteries in neuroscience: why some people are "right-brained" while others are "left-brained."

Toxic cell atlas can guide discovery of new drugs for neurodegeneration

A common thread in many inflammatory and neurodegenerative diseases, including multiple sclerosis (MS), is damage caused by oxidative stress. Oxidative stress occurs when cells produce toxic substances known as reactive oxygen species, which are damaging nerve cells and other cells in the body.
