[Chronic subdural hematoma: A variable clinical picture that asks for tailored treatment].

A chronic subdural hematoma is a common neurological disorder that occurs mainly in the elderly. The inciting event is often a minor head trauma and subsequent inflammation may play a role in the pathogenesis. The clinical spectrum can present heterogeneously, and symptom onset and progression can vary from days to weeks. To date surgical evacuation of the subdural collection remains the main treatment approach for symptomatic patients. Evidence is still scarce for dexamethasone as an effective primary conservative treatment strategy. Future research is necessary to elucidate the effect of various pharmacological therapies compared to primary surgery on functional outcome.
