Hemorrhagic Stroke
By admin December 15, 2016Hemorrhagic stroke—the type of stroke that is caused by bleeding into the brain—accounts for about 13 percent of strokes but about 40 percent of deaths by the stroke. Elevated blood pressure and inherited abnormalities in blood vessels are two things that can cause hemorrhagic stroke.
EEG After Concussion
By adminConcussion diagnosis is a notoriously tricky science.
Even if an assessment test on the sideline of a football or soccer field deems you to be concussion-free after a blow to the head, that doesn’t necessarily mean you didn’t suffer one, says Michael Singer, CEO of BrainScope, a Bethesda, Maryland-based company that has developed a new technology for detecting signs of a concussion in a person’s brain waves and has raised approximately $70 million from investors including the U.S. Department of Defense and the NFL.
There is no objective way to detect or assess a concussion, technically known as a mild traumatic brain injury, and BrainScope is trying to change that. Doctors diagnose them based mainly on signs and symptoms. Most people that come into the emergency room after hitting their head also get a computerized tomography (CT) scan to rule out very serious injury. But a CT scan doesn’t detect concussion.
