CBIS- Certified Brain Injury Specialist Exam
Questions with 100% Verified Answers Graded
A+
Acquired Brain Injury - ✅✅Injury to the brain that's not hereditary, congenital,
degenerative, or induced by birth trauma.
Coup-Contrecoup Injury - ✅✅When the head/brain moves forward (linear
acceleration) and then strikes an object with rapid linear acceleration of the brain,
resulting in frontal lobe focal lesions (this is coup). Then the rebound where the
brain/head moves backwards striking an object causing occipital lobe focal lesions
(contrecoup).
Closed Injuries - ✅✅Can cause brain lacerations and contusions, or
intracerebral hemorrhage within the brain causing fatal injuries. Examples of
closed injuries include "coup-contrecoup injury" or "diffuse axonal injury."
Hypoxia - ✅✅Low levels of oxygen
Anoxia - ✅✅An absence of oxygen
Hydrocephalus - ✅✅Buildup of fluid in the cavities (ventricles) deep within the
brain; Pressure of fluid is damaging.
CSF (cerebral spinal fluid)
, Incidence - ✅✅Rate or range of occurrences
Prevalence - ✅✅Refers to the number of people with a given condition at a
specific point in time
Mild TBI - ✅✅Can have either brief or no loss of consciousness and its
presentation may demonstrate vomiting, lethargy, dizziness, and inability to recall
what just happened.
Normal structural imaging; LOC= 0-30 minutes; AOC= from a moment up to 24
hours; PTA= 0-1 day; GCS= 13-15.
Moderate TBI - ✅✅Will be marked by unconsciousness for any period of time
up to 24 hours, will have neurological signs of brain trauma, including skull
fractures with contusion or bleeding, and may have focal findings on an EEG/CT
scan.
Normal or abnormal structural imaging; LOC > 30 minutes and < 24 hours; AOC >
24 hour severity based on other criteria; PTA > 1 and < 7 days; GCS= 9-12.
Severe TBI - ✅✅Marked by a period of loss of consciousness of 24 hours or
greater.
Normal or abnormal structural imaging; LOC > 24 hours; PTA > 7 days; GCS= 3-8.
