Primary and secondary brain injury - Wikipedia
In traumatic brain injury (TBI), primary brain injury occurs during the initial insult, and results from displacement of the physical structures of the brain. [1] Secondary brain injury occurs gradually and may involve an array of cellular processes.
Areas of the Brain Most Vulnerable during TBI: Location Matters

What Is a Traumatic Brain Injury? A traumatic brain injury (TBI) can be caused by a forceful bump, blow or jolt to the head or body, or from an object that pierces the skull and enters the brain. Not all blows or jolts to the head result in a TBI.
Cellular and Molecular Pathophysiology of Traumatic Brain Injury…
One of the most common and detrimental events that can generate permanent impacts on brain functioning is traumatic brain injury (TBI), which is a complex and heterogeneous disorder in the brain structure as a result of an external force in the form of mechanical, electrical, thermal or chemical energy, or a set of these, applied on it ...
The pathophysiology of traumatic brain injury at a glance
TBI models are used to study aspects of primary and secondary brain injury. Primary injury refers to the initial impact that causes the brain to be displaced within the skull. Secondary injuries gradually occur as a consequence of ongoing cellular events that cause further damage.
