Mystery Blood Vessel Disorder Implicated In 'Mini' Strokes

... disease, a significant cause of lacunar or "mini" strokes that can damage small areas of the brain. Depending on which area of the brain is affected, the strokes can impair functions such as movement, physical control of speech, or coordination. Multiple lacunar...

Next Generation Body Scanner Launched By The University Of Manchester

...ork. It will also help researchers looking into strokes and will enable them to understand the way the brain recovers in stroke patients. The scanner will also benefit researchers carrying out work into mental illness and will play a major role in the University's research into schizophrenia. The scan...

UK is first to administer new anti-clotting technology

...ch can block blood vessels, causing heart attacks, strokes and other debilitating or life-threatening conditions. Blood thinners, or antithrombotics, pose a risk of bleeding, particularly during surgery. The ability to stop the anti-clotting effects quickly could help protect patients from uncontrolled bleed...

Limiting the damage in stroke

...trongly suggests that new therapies for victims of strokes could be developed by controlling a molecule involved in passing the signal. Strokes lead to death or permanent disabilities for millions of people every year when an interruption of the flow of blood to brain cells deprives them of vital oxygen and...

Access to existing medical treatments could save more lives than spending to improve the treatments

...ration drugs saved fewer lives and prevented fewer strokes than if the existing drugs had been taken by all p...to all eligible patients would have prevented more strokes than were prevented by developing more potent and more expensive antiplatelet drugs, Woolf said. In...

New drug could reduce tissue damage after heart attack

...n almost all diseases including trauma, infection, strokes and chronic illnesses such as rheumatoid arthritis and Crohn's disease. CRP levels also rise dramatically after a heart attack. Patients with the greatest and most persistent increases in CRP concentration suffer higher mortality, and CRP is always...

Aspirin reduces cardiovascular risks in men and women -- but differently

'Word-vision' brain area confirmed

...atients with more customary lesions resulting from strokes or tumors, which often affect a larger extent of cortex and white matter. The small size of the present lesion thus provides precious support to the idea of partial regional selectivity for word perception in the ventral cortex," they wrote. Importa...

Researchers identify new cord blood stem cell

...em cells into laboratory rodents with experimental strokes resulted in significant reductions in the size of brain lesion, and improved these animals' use of their limbs. Some of the transplanted stem cells developed into "neuron-like" cells that are typically found in the brain. In addition, the transpla...

Bone and cartilage growth to blame for heart valve disease

... atrial fibrillation, which is a major culprit in strokes and heart failure. Aortic valve disease can lead to heart failure, arrhythmia, infections in the heart, and sudden death may occur in 15 to 20 percent of people who have symptoms. Dr. Rajamannan has focused her research for the past seven years on a...

Understanding the actions of others requires the frontal cortex

...e's actions, and it implies that people who suffer strokes to this region may also have difficulty understanding actions or gestures. Knowing more about the function of this brain area will help researchers develop better ways to communicate with stroke patients and understand more about how language and act...

Even fish don't swim well when they're young!

...suddenly it all clicks into place and a few feeble strokes of doggy-paddle propel you away from your parent's arms. Surely, you think, fish must be born as expert swimmers. Actually, fish larvae are pretty feeble when it comes to an efficient mode of swimming called 'burst-and-coast'. Dr Ulrike Müller from W...

Internal body clock dictates timing of different types of stroke

... evening, with a significant dip in the numbers of strokes occurring during sleep. But closer analysis showed that cerebral infarction had a higher peak in the morning and a lower peak in the afternoon than the other two. Intracerebral haemorrhage and subarachnoid haemorrhage, on the other hand, were mo...

What animals can tell us about hemorrhage, organ transplants and aging

...es that, we might be able to avoid the damage that strokes cause in humans," Andrews said. The ground squirrel's remarkable physiological abilities change with the seasons, Carey said. The animal's liver and heart remain viable outside the body for much longer during the hibernation season and the squirrel...

Cell death following blood 'reflow' injury tracked to natural toxin

...reperfusion injuries long linked to heart attacks, strokes and a variety of blood vessel injuries, the researchers pumped mouse nerve cells full of PAR-polymer. The cells died, but to be sure PAR-polymer (and not something else) killed them, they examined the brains of mice engineered to lack an enzyme that ...

New research shows big improvement in survival after stroke

...ralia and New Zealand. In New Zealand, over 7,600 strokes occur each year, while over 53,000 strokes take place in Australia per annum. However, research into stroke rates has shown a steady decline i...

It's in your head: The brain's own globin defends you from shock and stroke

...mportant step toward helping people who experience strokes or similar problems," said Gerald Weissmann, MD, Editor-in-Chief of The FASEB Journal. "Hemoglobin carries oxygen to all the body; neuroglobin defends our brain when it needs air. This article provides the first analysis of this exciting finding in b...

HIV dementia alarmingly high in Africa

In the first study of HIV dementia on the African continent using rigorous neurological and neuropsychological tests, 31 percent of a small but presumably representative group of HIV-posit...
