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.

Seasonal variation in blood pressure

A French study reported in the 12th January issue of Archives of Internal Medicine has found a strong correlation between blood pressure and outdoor temperature in a large sample of the elderly.

Electrical stimulation of the brain offers hope for Parkinson's sufferers

Electrical stimulation of the brain -- a treatment in which a pacemaker-like device sends pulses to electrodes implanted in the brain -- is riskier than drug therapy but may hold significant benefits for those with Parkinson's disease who no longer respond well to medication alone.

Numerical analysis estimates numbers of older US adults who may benefit from statin therapy

Researchers estimate more than 11 million older Americans may be newly eligible for statin therapy if findings from a recently published large clinical trial are adopted into clinical practice guidelines, according to a new analysis of the trial data.

Gene therapy kills brain tumors through selective recruitment of immune cells

Scientists seeking to harness the power of the immune system to eradicate brain tumors face two major hurdles: recruiting key immune cells called dendritic cells into areas of the brain where they are not naturally found and helping them recognize tumor cells as targets for attack.

Links between sleep apnea, stroke and death explained

Obstructive sleep apnea decreases blood flow to the brain, elevates blood pressure within the brain and eventually harms the brain's ability to modulate these changes and prevent damage to itself, according to a new study published by The American Physiological Society.

Implantable cardioverter defibrillators improve survival in older heart patients

Implantable cardioverter defibrillators (ICDs) can improve survival in patients with heart damage - even those in their 70s - according to research reported in Circulation: Cardiovascular Quality and Outcomes.

Apolipoprotein D protects against Alzheimer's

Do Carmo and her collaborators have successfully demonstrated the protective and reparative role of apolipoprotein D, or ApoD, in neurodegenerative diseases. Their discovery suggests interesting avenues for preventing and slowing the progression of this type of illness.

Carotid endarterectomy provides better short-term results than carotid artery stenting in patients with carotid artery disease

Carotid endarterectomy (CEA) yields better short-term results than carotid artery stenting (CAS) in patients with carotid artery disease, according to a 30-day outcomes report from the Society for Vascular Surgery (SVS) Vascular Registry for Carotid Procedures, published in the January 2009 issue of the Journal of Vascular Surgery, by the Society for Vascular Surgery.

Study examines impact of managed care on stroke prevention surgery

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.
