Regarding mtbi.do recovery occurs at the primary injury stage or the secondary injury stage of tbi?

Recovery takes time: With respect to mild tbi, recovery depends on the extent of initial symptoms and other factors. Research has shown that baseline physical condition before the injury, prior head injury or other neurologic disease, psychiatric disease, life stressors, student status, tbi after motor vehicle accident, and older age may be risk factors for persistent symptoms and longer recovery times.
