Traumatic Brain Injury Practice Test

The main idea is that how long symptoms last and how severe the initial injury was help tell the difference between post-concussive syndrome and lasting cognitive problems from brain injury. Post-concussive syndrome typically follows a mild TBI (a concussion) and includes headaches, dizziness, and cognitive complaints that hover for weeks to months after the injury, often without clear structural brain damage on imaging. When cognitive impairment persists after a moderate to severe TBI, it’s more likely due to ongoing structural injury to the brain and tends to have a longer, more protracted recovery—sometimes with imaging showing abnormalities. The other statements aren’t accurate because PCS is not identical to persistent impairment, imaging can be normal in PCS, and persistent impairment is not restricted to children.
