Stroke and Brain

Stroke is a diagnosis associated with old age. Stroke is the third leading cause of death and one of the top causes of disability in the United States.

Physicians know that strokes can occur at any age, but they sometimes make the mistake of thinking that stroke is a diagnosis of old age. Because of this, young adults who present to emergency rooms may be misdiagnosed.

Ankle Splints Improve Mobility After Stroke

Jan 29 2009 - 10:28am

A new review shows that ankle and foot splints can help stroke patients regain the ability to walk and keep their balance, although splints — also called orthotics — offer less improvement for other activities, like climbing stairs.

Wrist splints, however, do not lead to signs of improvement in the hands or arms, according to the new review.

Stents Can Treat, Not Just Prevent Strokes

Jan 20 2009 - 12:00pm

Stents can be placed in the brain to treat a stroke as it's occurring, suggests preliminary data being presented at the 21st Annual International Symposium on Endovascular Therapy (ISET).

Stents have long been used to open up blocked blood vessels in the heart to prevent heart attacks and in the neck to prevent strokes. More recently stents have been used in the heart to treat occurring heart attacks by opening up the blocked arteries. This early research suggests stents also can be used to treat occurring strokes, by opening up blocked arteries in the brain.

Smoking Plus Family History Ups Stroke Risk from Aneurysm Six-Fold

Jan 2 2009 - 10:33am

Those with a family history of stroke from an aneurysm are now found to have a six-fold increase in stroke risk from aneurysm, directly related to smoking.

The new study, published in the American Academy of Neurology, studied 339 people who suffered stroke from aneurysm, a blood vessel weakness that results in brain hemorrhage, leading to stroke. The condition is fatal in thirty-five to forty percent of cases. The researchers also compared 1,016 people who had not had a stroke due to an aneurysm. Half of the stroke groups were current smokers; the other half either quit or never smoked.

The impact of managed care on stroke prevention surgery

Dec 29 2008 - 10:29am

Policymakers and economists often promote managed-care plans based on the assumption that they prevent the overuse of unnecessary surgical procedures or help steer patients to high-quality providers, compared to traditional fee-for-service insurance plans. A recent study by a researcher at UT Southwestern Medical Center, however, found that in the case of one common surgical procedure, the checks and balances assumed with managed care did not improve the quality or outcome of care.

Ultrasound Screening Prevents Stroke In Children With Sickle Cell Disease

Dec 9 2008 - 8:35am

Screening with an ultrasound machine has proved highly successful in preventing stroke among children with sickle cell disease, by identifying children who are then preventively treated with blood transfusions. Over an eight-year period at The Children's Hospital of Philadelphia, researchers found that the technique, transcranial Doppler ultrasonography (TCD), along with regular transfusions for children found to be at high risk, reduced stroke to one-tenth of the incidence found before TCD was introduced.

Stroke Awareness Campaign Saves Lives

Dec 8 2008 - 9:43am

A three-year pound 12 million communications campaign to promote public awareness around stroke was announced today by Health Minister Ann Keen.

The campaign will be launched in February 2009, and will be supported by advertising, public relations and direct marketing communications.

Stroke, the loss of brain function due to a blood clot or bleed in the brain, is the third leading cause of death in the UK and the single largest cause of adult disability in England.

Specialized Care, Telemedicine Improves Stroke Outcomes

Nov 21 2008 - 12:51pm

Stroke patients have significantly better chances of surviving and living independently when they receive specialized stroke care in community hospitals that have telecommunication support from major stroke centers, according to a study in Stroke: Journal of the American Heart Association.

At 12 and 30 months after stroke, patients treated at hospitals with specialized stroke units had a significantly lower rate of “death and dependency” than did patients who received care at hospitals without stroke units. Dependency was defined as
disability or need for institutional care.

Findings Of Major New Stroke Study Are Good News

Oct 16 2008 - 5:06am

A study published in issue of the New England Journal of Medicine shows that doctors may have an additional 90 minutes to successfully administer clot-busting drugs to patients who suffer the most common type of stroke - an ischemic stroke - which is caused by a blood clot or other blockage within an artery leading to the brain.

Current treatment standards allow doctors to use clot-busters intravenously up to three hours after stroke symptoms begin. The new findings indicate that the drugs can reduce or eliminate effects of a stroke for as long as four and a half hours after onset.

Gene May Cause Stroke-Inducing Malformations

Sep 9 2008 - 9:21am

UCSF scientists have discovered that a gene controlling whether blood vessels differentiate into arteries or veins during embryonic development is linked to a vascular disorder in the brain that causes stroke.

The UCSF studies were done in mice, and the new findings are the first to provide information on both the progression and regression of this particular brain disorder, known as BAVM, and to provide molecular clues into the disease, which is not well-understood and chiefly affects young people.
