(HealthDay)—Prompt treatment of a mini-stroke could reduce the likelihood of having a full-blown stroke by roughly 80 percent, according to a new report. People who have a mini-stroke—officially called a transient ischemic attack (TIA)—typically recover from symptoms, such as trouble speaking or paralysis, within minutes. But a trio of neurologists from Loyola University Medical Center...

Hibernating ground squirrels provide clues to new stroke treatments
IMAGE: A TEAM OF SCIENTISTS IDENTIFIED A MOLECULE THAT MAY REDUCE STROKE-INDUCED BRAIN DAMAGE. In the fight against brain damage caused by stroke, researchers have turned to an unlikely source of inspiration: hibernating ground squirrels. While the animals’ brains experience dramatically reduced blood flow during hibernation, just like human patients after a certain type of...

Anti-cancer drugs could prevent the hardening of blood vessels that cause heart attack and stroke
Anti-cancer drugs could prevent the build-up of fatty plaques in blood vessels which cause heart attack and stroke, a new study by the University of Sheffield has shown. The new research, funded by the British Heart Foundation, suggests drugs which are already in clinical trials for the treatment of cancers could be repurposed to prevent atherosclerosis –...

When it comes to strokes, timing is everything
Sudden onset of blurred vision, slurred speech, numbness or paralysis in the face, arm, or leg can be indications of a stroke. Oftentimes, many wait to seek help, but this can be a fatal mistake: the risks of permanent damage or death increase the longer treatment is delayed. In fact, six million people die and...

A new approach to improving hemispatial neglect after stroke
Jacinta O’Shea from the Nuffield Department of Clinical Neurosciences explains how stimulation of the brains of stroke patients can cause long-lasting improvements. Every year thousands of people are left with debilitating symptoms after stroke. Perhaps one of the most striking is known as hemispatial neglect. This is when right-sided brain damage causes people to behave as...

Combined rTMS and virtual reality brain-computer interface training for motor recovery after stroke
Abstract OBJECTIVE: Combining repetitive transcranial magnetic stimulation (rTMS) with brain-computer interface (BCI) training can address motor impairment after stroke by down-regulating exaggerated inhibition from the contralesional hemisphere and encouraging ipsilesional activation. The objective was to evaluate the efficacy of combined rTMS + BCI, compared to sham rTMS + BCI, on motor recovery after stroke in subjects with lasting motor...

A quick jab could reduce stroke damage
A Perth treatment could significantly reduce the damage done to brain cells following a stroke. Diego Milani from the University of Notre Dame Australia has been testing a new compound that has been shown to reduce damage in the brain after a stroke. The compound is made up of 18 molecules of the amino acid arginine...

The rat race is over: New livestock model for stroke could speed discovery
Associate Professor Franklin West and Emily Baker working with induced pluripotent stem cells generated from a patient’s own somatic cells. It is well-known in the medical field that the pig brain shares certain physiological and anatomical similarities with the human brain. So similar are the two that researchers at the University of Georgia’s Regenerative...

Team discovers how to train damaging inflammatory cells to promote repair after stroke
White blood cells called neutrophils are like soldiers in your body that form in the bone marrow and at the first sign of microbial attack, head for the site of injury just as fast as they can to neutralize invading bacteria or fungi using an armament of chemical weapons. But when that injury is an intracerebral hemorrhage,...

Domiciliary VR-Based Therapy for Functional Recovery and Cortical Reorganization: Randomized Controlled Trial in Participants at the Chronic Stage Post Stroke
Abstract Background Most stroke survivors continue to experience motor impairments even after hospital discharge. Virtual reality-based techniques have shown potential for rehabilitative training of these motor impairments. Here we assess the impact of at-home VR-based motor training on functional motor recovery, corticospinal excitability and cortical reorganization. Objective The aim of this study was to identify...
