[116] Research since the early 1990s has improved TBI survival; [179] that decade was known as the "Decade of the Brain" for advances made in brain research ...
Trauma; multiple traumatic injuries can lead to chronic traumatic encephalopathy. A coup-contrecoup injury occurs when the force impacting the head is not only strong enough to cause a contusion at the site of impact, but also able to move the brain and cause it to displace rapidly into the opposite side of the skull, causing an additional ...
