Primary And Secondary Brain Injury
Primary and secondary brain injury are ways to classify the injury processes that occur in brain injury. In traumatic brain injury (TBI), primary injury occurs during the initial insult, and results from displacement of the physical structures of the brain. On the other hand, secondary injury occurs gradually and may involve an array of cellular processes. Secondary injury, which is not caused by mechanical damage, can result from the primary injury or be independent of it. The fact that people sometimes deteriorate after brain injury was originally taken to mean that secondary injury was occurring. It is not well understood how much of a contribution primary and secondary injuries respectively have to the clinical manifestations of TBI.
Primary and secondary injuries occur in insults other than TBI as well, such as spinal cord injury and stroke.

Famous quotes containing the words primary, secondary, brain and/or injury:
“The traditional American husband and father had the responsibilities—and the privileges—of playing the role of primary provider. Sharing that role is not easy.

—Faye J. Crosby (20th century)
“A man may be defeated by his own secondary successes.”
—Woodrow Wilson (1856–1924)

They’ve got to leave that brain outside,
And vote just as their leaders tell ‘em to.”
