Brief Summary
In a multi-national population-based cohort, the investigators want to compare the clinical course and clinical outcome of elderly patients (≥70 y/o) compared with younger patients (\< 70 y/o) with acute subdural hematoma treated surgically. An improved understanding of the clinical outcome and the prognostic factors of acute subdural hematomas would allow physicians to make better decisions about treatment options in traumatic ASDH in the elderly population.
