Genetic Predictor of Serious Brain Stroke Complications Discovered

University of Florida Health researchers have found a possible predictor for little understood — but often disabling or even fatal — stroke complications.

The findings, published in the journal Proceedings of the National Academy of Sciences, may extend to other neurological disorders, said Sylvain Doré, lead author and a professor of anesthesiology, neurology, psychiatry, pharmaceutics and neuroscience at UF’s College of Medicine.

For the study, Doré and his team looked at patients who had suffered a subarachnoid hemorrhage, a type of stroke that affects as many as 30,000 Americans each year and accounts for 5 percent of all strokes, according to the American Heart Association. Most often caused by the rupture of an aneurysm, subarachnoid hemorrhage occurs when there is bleeding in the area between the brain and the thin tissues that cover the brain — often causing death or long-term impairment and disability.
