Stroke Overview

Stroke, also known as cerebrovascular accident (CVA), cerebrovascular insult (CVI), or brain attack, is when poor blood flow to the brain results in cell death. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding.

In 2013, stroke was the second most frequent cause of death after coronary artery disease, accounting for 6.4 million deaths (12% of the total). About 3.3 million deaths resulted from ischemic stroke while 3.2 million deaths resulted from hemorrhagic stroke. About half of people who have had a stroke live less than one year.

JHU BLAM Lab and the Kata Project

The Kata Project, part of the Brain, Learning, Animation, and Movement (BLAM) Lab at John Hopkins university, combines the excellence of Hopkins academics with the freewheeling creativity of the interactive entertainment and media technology worlds.

The Kata Project will bring together domains of expertise rarely seen in the same physical space: young, imaginative, and elite engineers who are usually lost to a parallel universe outside of academia and neuroscientists and clinicians within the academy.

Imaging identifies asymptomatic people at risk for stroke

Imaging can be a cost-effective way to identify people at risk for stroke who might benefit from aggressive intervention, according to a new modeling study.

The study looked at people with asymptomatic carotid artery stenosis, a narrowing of the major blood vessels supplying blood to the head due to atherosclerosis, or plaque buildup.

At A Glance

Cerebrovascular reserve (CVR) testing with transcranial Doppler (TCD) sonography can identify people with asymptomatic carotid artery stenosis who may benefit from medical intervention to prevent stroke. Carotid artery stenosis is the primary cause of up to 20 percent of ischemic strokes. CVR testing appeared to have a favorable balance of benefits and costs.
