Section 3
Typical Causation: Trauma
• Open head injury- dura mater pierced
• Closed head injury-dura mater intact
• Contrecoup effect-brain injury at side of impact, but could be on opposite side
• Most common reason for youths
This slide is essentially an FYI. However, it does provide insight to the concept of closed versus open head injuries.

When blood from a trauma irritates brain tissues, it causes swelling. This is known as cerebral edema. The pooled blood
collects into a mass called a hematoma.
