A new studypoints to an increased risk of suffering a stroke after a traumatic brain injury. The study found that persons who had suffered a brain injury have a ten-times higher risk of suffering a stroke during the first three months after injury. This means that anyone involved in a car accident, construction accident or any other trauma that results in a traumatic brain injury has a much higher likelihood of suffering a stroke.
The results of the study have been published in the online issue of Stroke: Journal of the American Heart Association, and confirms that a traumatic brain injury can increase the risk of suffering a stroke over five years.The researchers based their results on an analysis of data of about 23,000 patients from a Taiwanese database.All these persons had suffered a traumatic brain injury.These people were then compared to people with no history of brain injury.The researchers monitored their susceptibility to stoke over a period of 5 years.
The increase is the most dramatic during the first three months after the TBI.After one year, the stroke risk went down substantially, but it was still at least 4.6 times higher than among people who did not have a traumatic brain injury.After five years, the stroke risk was 2.3 times higher than among patients with no brain injury.
