Have a Brain Injury? You May Be at Higher Risk for Stroke

27.06.2013
People who have a traumatic brain injury (TBI) may be more likely to have a future stroke, according to research that appears in the June 26, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology.

“Both stroke and traumatic brain injury are common, costly, and leading causes of severe disability in adults, and approximately 20 percent of strokes occur in adults under age 65,” said study author James F. Burke, MD, MS, of the University of Michigan and the Ann Arbor VA Healthcare System and a member of the American Academy of Neurology.

“A large proportion of stroke risk is unexplained, especially in the young, so if we can identify new risk factors, we have the potential to prevent more strokes and improve outcomes.”

For the study, researchers looked at the records of adults who went to the emergency department or were admitted to a hospital for TBI or other trauma with no brain injury in the state of California during a five-year period. A total of 435,630 people with traumatic brain injury were studied, along with 736,723 people with trauma with no brain injury. Over an average of 28 months following the injury, 11,229 people, or 1 percent, had an ischemic stroke.

A total of 1.1 percent of those with TBI suffered a stroke, compared to 0.9 percent of those with trauma with no brain injury. With an ischemic stroke, blood flow to part of the brain is blocked. Eighty percent of strokes are ischemic.

After adjusting for factors that can affect stroke risk, such as age, high blood pressure and high cholesterol, as well as other disorders such as heart disease and the severity of the trauma, the researchers found that people with traumatic brain injury were 30 percent more likely to develop a stroke than those with trauma with no brain injury.

“While the stroke risk of one person with TBI is small, the overall link between TBI and stroke was substantial— as large as the link between the strongest stroke risk factor, high blood pressure, and stroke,” Burke said. “If further research establishes TBI as a new risk factor for stroke, that would stimulate research to help us understand what causes stroke after TBI and help us learn how to prevent these strokes.”

The study was supported by an advanced fellowship through the Department of Veterans Affairs.

The American Academy of Neurology, an association of more than 26,000 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Alzheimer’s disease, stroke, migraine, multiple sclerosis, brain injury, Parkinson’s disease and epilepsy.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
