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.

Immune cells may play crucial role in helping the brain heal after hemorrhage or stroke

While immune cells called neutrophils are known to act as infantry in the body's war on germs, a National Institutes of Health-funded study suggests they can act as medics as well. By studying rodents, researchers showed that instead of attacking germs, some neutrophils may help heal the brain after an intracerebral hemorrhage, a form of stroke caused by ruptured blood vessels.

School-based education about strokes can improve victims’ survival chances without lasting damage

In the treatment of strokes, every minute gained can save lives or reduce the extent of lasting damage. At the World Congress for Neurology in Kyoto, Japanese doctors presented an effective educational program for school children and their parents.

Study overturns common belief about how proteins regulate formation of sensory interneurons

A recent study led by Samantha Butler at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA has overturned a common belief about how a certain class of proteins in the spinal cord regulate the formation of nervous system cells -- called neurons -- during embryonic development.

Research deepens understanding of interconnection between nervous and immune system

A newly-discovered reflex arc mediates a process which leads to a disruption in the hormones secreted by the adrenal glands which, in turn, results in an increased susceptibility to bacterial infections.

New tablet-based video monitoring technology could alert onset of atrial fibrillation

Today, tablets are ubiquitous. While many of us reach for them to scan Facebook, watch the newest series on Netflix, or make a quick purchase on Amazon, researchers want to test their potential for a more serious task: detecting atrial fibrillation (afib).

New shingles vaccine gets FDA panel votes

On the 13th of September 2017, a U.S. Food and Drug Administration (FDA) advisory panel has voted 11 to 0 approving a shingles vaccine for its use in adults aged 50 and over. The panel unanimously accepted the safety and efficacy of the vaccine and thus GlaxoSmithKline’s Shingrix is on its way to FDA approval.

Brain rewiring due to dopamine loss may be source of impaired movement in Parkinson's disease

The brain's own mechanisms for dealing with the loss of dopamine neurons in Parkinson's disease may be a source of the disorder's abnormal movement, according to a Northwestern Medicine study published in Neuron.

Modified blood thinner may be first promising method to prevent repercussions after TBI

A chemically modified version of the common blood thinner heparin may be the first promising method of preventing the harmful cascade of destruction to brain tissue that commonly follows traumatic brain injury (TBI), according to new research findings.

Hormone therapy for menopausal symptoms does not increase mortality risk, according to a long-term study

An 18-year follow-up study of postmenopausal women in the Women’s Health Initiative trials has shown that the use of hormone therapy was not associated with any increased risk of all-cause, cardiovascular or cancer death.

NIH awards $15 million to develop 3D microphysiological system platforms that model human disease

More than 60 percent of investigational drugs fail in human clinical trials due to a lack of effectiveness, despite promising pre-clinical studies using cell and animal research models.

Long periods of sitting may increase early death risk

A new study finds that it isn't just the amount of time spent sitting, but also the way in which sitting time is accumulated during the day, that can affect risk of early death.

UAlberta chemistry professor develops revolutionary neuroscience tools

UAlberta chemistry professor Robert Campbell is developing new ways to see and manipulate the activity of neurons in the brain, which could revolutionize the way we understand the organ that controls most of the activities of the body.

Desk job? Get up and move every half an hour !

According to a new study sitting for long periods of time at a single stretch is linked to early death. The study explored the effects of sitting versus moving around and found that it is not only the amount of time spent sitting but also the way in which the total time spent sitting is accumulated throughout the day that counts to affect lifespan detrimentally.

E-cigarettes associated with increased blood pressure, heart rate, and arterial stiffness, study reveals

A new study, presented at the European Respiratory Society International Congress, suggests that use of e-cigarettes with nicotine causes arterial stiffness in humans, and has significant consequences leading to risk of heart disease and stroke later in life.
