Silent stroke may be the most common form of brain injury in children with sickle cell anemia, a rare, painful blood disorder. Recently, researchers have been able to pinpoint the risk factors for such strokes in children.

Some individuals may be at a higher risk of stroke simply by nature of their blood type. Those with blood type AB may be at an increased risk of stroke regardless of other factors.

An experimental drug designed to aid severely ill patients after hospitalization is not more effective than standard treatments for reducing the risk of blood clots, a study has confirmed.

Atrial fibrillation, a common heart arrhythmia, is generally treated with a standard drug warfarin. However, a study suggests a new drug might provide the same treatment, but with a lower risk of stroke and embolism.

Clot busting drugs reduce stroke disability, yet patients often don't receive the treatment. It appears that graduating neurology residents are becoming more comfortable with using the drug.

Inherited bleeding and clotting disorders are not well understood. Scientists hope that a study to create human platelet cells, which could aid chemotherapy patients in need of platelet transfusions, will provide insight into platelet function.

Strokes can be tough to treat. Scientists have discovered a common genetic thread with plaques that can build up and lead to stroke. It could be a key piece of the puzzle in new treatments.

There's the traditional "stroke belt" across the southeastern United States where death from stroke is much higher. But new research suggests there also is a "blood stream infection belt" that very closely mirrors the stroke belt.

Compared to any number of dangerous situations someone can find themselves in, driving a car fueled by diesel hardly seems risky. But exhaust fumes may be deceptively nipping at heart health.

Patients with acute coronary syndromes often must resort to stents or balloon angioplasty to relieve artery constriction. Now the European Society of Cardiology is suggesting new strategies to minimize bleeding during such procedures.
