There is very little extra room within the skull, so the build-up of blood puts pressure on the brain.
What are the causes and risks of the injury?
Persons traveling at any increased speed are at risk for hematoma whenever the head is struck. During impact, the brain moves around inside the skull. Veins may tear, spilling blood into the subdural space. As people age, brains shrink slightly, so veins are stretched. Thus, the elderly are more susceptible to this type of injury. Other conditions that put people at risk for subdural hematoma include:
