Study Finds Potential Link between Traumatic Brain Injury and Subsequent Ischemic Stroke

Laptop and Stethoscope

Approximately 1.7 million people in the United States suffer some form of traumatic brain injury every year, and of those 1.7 million people nearly 400,000 of them are injured badly enough that they face the possibility of dealing with long-term disabilities. Clearly, anyone who suffers a brain injury will have a lot to worry about in the future, as this type of harm can lead to both lingering symptoms and changing symptoms in the weeks, months or even years that are yet to come. That's why researchers are working diligently to try to identify as many potential risks as possible.

Depending on one's perspective, it's either fortunate or unfortunate that researchers may have recently discovered a link between the suffering of a traumatic brain injury and the subsequent suffering of an ischemic stroke. This is obviously not good news for people who have endured head trauma, but it may be a positive in that doctors may now be able to watch for signs that this could happen and work to either prevent it or minimize the damage that's done.Researchers at the University of Michigan recently completed the study, which was published in the journal known as Neurology. The text for the study can be found here. The researchers went about their study by combing through the discharge records of traumatic brain injury patients in California between 2005 and 2009. They tracked more than 1.35 million patients, 37 percent of whom were admitted because of brain trauma.

Those patients were tracked for subsequent admissions for ischemic stroke and compared to another group of patients who had not suffered brain trauma originally. After all of the statistical adjustments were made and different variables such as age and demographics were accounted for, the researchers concluded that suffering a traumatic brain injury raised the risk of suffering an ischemic stroke within 28 months of the original injury by a factor of 31 percent when compared to the other patients.

Overall, this potential comparison point ties traumatic brain injuries to ischemic stroke risk factors as strongly as other factors that were already known such as hypertension and type 2 diabetes. The researchers suggested in conclusion that injuries such as concussions can lead to damage in the blood vessels in the brain that can eventually lead to blood flow problems that will manifest themselves in some point as an ischemic stroke.

This could prove to be an important discovery if additional research confirms these findings. It will be extremely important knowledge if the identification of a traumatic brain injury as a risk factor for strokes leads to the formulation of preventative measures that can help to lower the risk of this result occurring over time.
