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.

New technology to help physicians and engineers pool resources to prevent stroke

A professor at the University of Houston and his research students are working with physicians and scientists at the Methodist Neurological Institute on new technology to help identify which brain aneurysms are at highest risk of rupture and could cause a stroke.

MRI clues identify stroke victims at risk of skull hemorrhaging

The appearance of parenchymal enhancement of stroke lesions and the hyperintense MCA sign on MRI may help identify stroke patients at risk of hemorrhaging in the skull, says a new study by researchers at Shantou University Medical College in China and the University of Toronto in Canada.

The 30-year natural history of type 1 diabetes complications

...while cases of premature death and a few other complications have declined, rates of other serious diabetes-related disorders such as heart and eye disease have not improved over the past 25 to 30 years.

Economic benefit of federally finded clinical trials exceeds $15 billion

A comprehensive review of all phase III clinical trials supported by one Federal agency finds that, estimated conservatively, the economic benefit in the United States from just eight of these trials exceeded $15 billion over the course of 10 years. The study also found that new discoveries from the trials were responsible for an estimated additional 470,000 healthy years of life. The clinical trials were sponsored by the National Institutes of Health's National Institute of Neurological Disorders and Stroke (NINDS).

Osteoporosis could be caused by factors other than declining estrogen levels

New evidence in the April 21, 2006 Cell challenges the long-standing notion that declining estrogen levels alone lead to osteoporosis after women go through menopause. The researchers rather found that high levels of pituitary-derived follicle-stimulating hormone (FSH) cause bone loss in mice. The pituitary is a master gland found at the base of the brain.

Blood pressure readings lower if patients are allowed to relax and be comfortable

According to a new study from a team of nurses headed by Melly Turner, R.N., systolic blood pressure can be an average of 14 points higher when taken immediately after arriving in the exam room and sitting on an examination table rather than sitting in a chair with your back supported and feet flat on the floor. In fact, all study participants had lower systolic and diastolic blood pressure measurements when seated in a chair versus the exam table.
