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.

Researchers receive $14 million grant to study the effectiveness of hydrocephalus treatment

Patients diagnosed with idiopathic normal pressure hydrocephalus (iNPH), a type of brain swelling most commonly seen in older adults — and for which the underlying cause is unknown — are typically treated by surgically installing a shunt (drain) to remove the excess fluid associated with the condition.

Stiffening of heart’s blood vessels associated with lack of enzyme that fosters cell ‘chatter’

In a study in mice, Johns Hopkins Medicine researchers have found that the smooth muscle cells lining the walls of blood vessels can lose their elasticity and lead to vascular stiffening, a condition that can precede heart disease and stroke.

Athletes with history of concussions may show subtle and chronic brain changes

A new study suggests athletes with a history of concussion may show more brain injury from a later concussion, particularly in middle regions of the brain that are more susceptible to damage, when compared to athletes with no history of concussion.

Portable MRI can help identify intracranial hemorrhages in stroke patients

When patients exhibit stroke symptoms, doctors must quickly make a life or death determination: Are their symptoms caused by a clot that can be treated with blood thinners or by bleeding in the brain, which may require surgery?

Researchers identify eight primary factors that increase GI bleeding risk after heart attack

Researchers at Karolinska Institutet in Sweden have identified eight primary factors that increase the risk of a common bleeding complication after heart attack. Some of these factors are already known, but using machine learning techniques, the researchers have found additional predictors, such as smoking, blood pressure and blood glucose.
