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.

Research suggests a central role for NMDA receptors in learning and memory

Learning and memory are processes that link experience with behavior and therefore play central roles in our daily experience. That there exists a physical basis for these processes seems at first hard to imagine--except for the fact that physical disruptions in the brain, such as stroke or disease, can make them go wrong.

Cardiovascular Disease: Diet, Nutrition And Emerging Risk Factors

Despite improvements in death rates from cardiovascular disease (CVD) around the world, CVD remains a leading cause of death and ill health in the UK, where death rates are amongst the highest in the world. Reducing death rates from this disease remains high on the Government’s agenda, yet attention to the classical risk factors may not provide all the answers.

Diuretics work better for high blood pressure

Study results by faculty members of the University of Texas School of Public Health at Houston suggests that the older, cheaper diuretics remain the drug of choice for both black and non-black patients in treating high blood pressure and reducing risk of heart disease, and confirms earlier findings that diuretics rather than newer, more expensive drugs such as ACE inhibitors, calcium channel blockers, or beta blockers should be preferred as a first therapy for most patients.

UK study links heart conditions with common ‘hidden’ hormone disorders in the elderly

A study of nearly 6000 elderly people in Birmingham has shown that ‘hidden’ thyroid disorders are common in over-65s and that there is a strong link between one type of abnormality and irregular heartbeat. The work will be presented at the British Endocrine Societies 2005 meeting in Harrogate on Wednesday.

Newer imaging technologies may lead to over treatment

Newer imaging technologies allow physicians to visualize more of the arteries in the lungs, including detecting small blood clots not previously seen, but seeing more may have little impact on the patient’s outcome, a new study suggests.

Study of Anoxia could yield better anesthetics, stroke/heart attack recovery

For a human, mere minutes without oxygen (called anoxia) resulting from cardiac arrest, cerebral stroke or being trapped under water can lead to profound tissue damage and even death. However a Western painted turtle can survive anoxia for months without apparent tissue damage. Why, and how?
