Table 5. Repeat imaging and neurologic exam.

Imaging was obtained either routinely or for a change in the neurologic exam defined as a drop in Glasgow Coma Scale score by ≥2 points, anisocoria, focal neurologic deficit, seizure, worsening/severe headache, nausea, or vomiting.

EDH, epidural hematoma; SDH, subdural hematoma; SAH, subarachnoid hemorrhage; IPH, intraparenchymal hemorrhage; IPC, intraparenchymal contusion
