How is neuroradiology used in the diagnosis of TBI? This microscopic injury leads to many of the persistent problems which TBI patients may experience. Second is injury to microscopic nerve fibers (axons), which constitute the “wiring” that connects nerve cells in the brain (neurons) to each other and to the rest of the body. These injuries occur in more severe forms of TBI and are typically absent in mild TBIs. First, actual bruising or tearing of brain tissue and bleeding within or surrounding the brain may occur, with subsequent brain swelling (edema). Multiple concussions may increase the risk for long-term problems and have been linked to the development of delayed brain degeneration. Some concussion patients, however, will experience persistent problems related to their TBI. The good news about concussion is that most patients recover over a relatively brief period of time.
However, more than 75% of TBIs are mild and referred to as concussion concussion is also a physical injury to the brain. The most severe cases may result in immediate or later death of the patient. TBI ranges in degree from severe to mild.
Similarly, the severity of trauma to the head does not necessarily determine the severity of a TBI, when it occurs. However, every blow to the head will not necessarily result in TBI in every individual. TBI may occur when force is applied to the brain, either through a direct impact to the head or its rapid acceleration and deceleration, as in whiplash. While many symptoms, such as headache, memory problems, difficulty concentrating and visual changes, are common among TBI patients, rarely will two individuals experience exactly the same problems due to TBI. Because the brain supervises and controls almost all aspects of normal human function, physical, psychological, hormonal or otherwise, injury to the brain (TBI) may result in a wide array of medical, psychological and behavioral problems. We are all increasingly aware of traumatic brain injury (TBI), whether through the news, media or personal experience, but what exactly is TBI? TBI is a physical injury to the brain, which has many causes including vehicle crashes, falls, assault, contact sports and military combat.
