A. Diffuse Axonal Injury (DAI)
B. Cerebral / Cortical Contusion
C. Concussion
D. Post Concussional Syndrome
A. Diffuse Axonal Injury (DAI)
Primary Injury: Deceleration and acceleration injury causes shear, tensile,
and compression forces within / to the brain
A. Diffuse Axonal Injury (DAI)
B. Cerebral / Cortical Contusion
C. Concussion
D. Post Concussional Syndrome
A. Diffuse Axonal Injury (DAI)
Primary Injury: Predominant MOI in most individuals with severe to moderate TBI
A. Diffuse Axonal Injury (DAI)
B. Cerebral / Cortical Contusion
C. Concussion
D. Post Concussional Syndrome
A. Diffuse Axonal Injury (DAI)
Primary Injury: Occurs with translation acceleration result in head movement
A. Diffuse Axonal Injury (DAI)
B. Cerebral / Cortical Contusion
C. Concussion
D. Post Concussional Syndrome
B. Cerebral / Cortical Contusion
Primary Injury: Mechanism behind initial loss of consciousness after TBI and results in more generalized deficits (e.g. confusion
and incoordination)
A. Diffuse Axonal Injury (DAI)
B. Cerebral / Cortical Contusion
C. Concussion
D. Post Concussional Syndrome
A. Diffuse Axonal Injury (DAI)
Primary Injury: Elevates the risk for seizures and is more likely to produce focal deficits (e.g. aphasias and motor weakness)
A. Diffuse Axonal Injury (DAI)
B. Cerebral / Cortical Contusion
C. Concussion
D. Post Concussional Syndrome
B. Cerebral / Cortical Contusion
Primary Injury: Headache, agitation, fatigue, irritability, memory deficit, and concentration loss occurring 3 months after the concussion.
A. Diffuse Axonal Injury (DAI)
B. Cerebral / Cortical Contusion
C. Concussion
D. Post Concussional Syndrome
D. Post Concussional Syndrome
Common areas of a contusion are the undersurface of the (1)____ and (2)____ lobes due to the presence of bony prominences on the base of the skull creating brain tissue and vascular
disruption.
- frontal lobe (leads to long term amnesia)
- anterior temporal lobe (leads to short term amnesia)
TRUE OR FALSE: Comatose is a common manifestation of diffuse axonal injury. Recovery from DAI is usually gradual and is commonly
linked to the duration of the coma.
True
Primary Injury: Loss of consciousness d/t direct axonal shearing and
disruption of the intra-axonal cytoskeleton. Then, the axonal disruption leads to swelling.
A. Diffuse Axonal Injury (DAI)
B. Cerebral / Cortical Contusion
C. Concussion
D. Post Concussional Syndrome
A. Diffuse Axonal Injury (DAI)
Primary Injury: Refers to neurons remote from a site of injury, but anatomically connected to the damaged area, becoming functionally depressed
A. Direct Laceration
B. Diaschisis
C. Epidural Hematoma
D. Subdural Hematoma
B. Diaschisis
Primary Injury: Focal cortical lesions that can affect contralateral cortical functioning by way of interconnections in the corpus callosum
A. Direct Laceration
B. Diaschisis
C. Epidural Hematoma
