Thanks to a friend and follower of the blog I have been looking at some traumatic brain injury (TBI) research. Often you see TBI and concussion near each other; you can think of them as brother and sister. They are cut from the same cloth, meaning it is the same mechanisms that cause both. Concussions are referred to as minor traumatic brain injuries (mTBI) due to the lack of diagnostic (see imaging) findings with altered mental status or signs/symptoms. Regardless traumatizing the brain is not something that is good for you on a consistent basis.
The first article is about the link between TBI and stroke;
If you suffer traumatic brain injury, your risk of having a stroke within three months may increase tenfold, according to a new study reported in Stroke: Journal of the American Heart Association.
“It’s reasonable to assume that cerebrovascular damage in the head caused by a traumatic brain injury can trigger either a hemorrhagic stroke [when a blood vessel bursts inside the brain] or an ischemic stroke [when an artery in the brain is blocked],” said Herng-Ching Lin, Ph.D., senior study author and professor at the School of Health Care Administration, College of Medicine, Taipei Medical University in Taiwan. “However, until now, no research had been done showing a correlation between traumatic brain injury and stroke.”
It is the first study that pinpoints traumatic brain injury as a potential risk factor for subsequent stroke.
