Eligibility Criteria:
Inclusion Criteria:~* Male or female subject aged 18 years of age or older~* Informed consent obtained from a patient or a legal representative before enrollment~* Enrollment into the study within 12 hours of detection of chronic subdural hematoma on cranial imaging~* Presence of symptoms referable to chronic subdural hematoma, including one or more of the following: Headache; altered mental status, limb weakness, dysphasia, or focal neurological deficit~* Demonstration of unilateral chronic subdural hematoma on cranial imaging, including the following features: On computed tomography imaging, iso- or hypo-intensity extra-axial collection with or without presence of acute component; radiologic interpretation of magnetic resonance imaging consistent with subacute or chronic SDH; with or without evidence of acute hemorrhagic component~* Maximum depth of subdural hematoma of less than 20mm, with less than 10mm of midline shift, as measured on axial CT or MR imaging~* Absence of skull fracture over the subdural hematoma~* Able to receive the drug treatment~Exclusion Criteria:~* Presence of skull fracture over the subdural hematoma, or other specific etiology for cSDH not suitable for drainage by burr hole craniostomy, such as presence of a ventriculoperitoneal shunt~* Extent of subdural hematoma \> 20mm in maximal depth, or \> 10mm of midline shift, as measured on axial CT or MR imaging~* GCS \<8 or cSDH of an extent or size for which craniotomy, rather than burr hole drainage alone, is judged necessary by the neurosurgery attending on call~* Prior diagnosis of dementia~* Presence of symptomatic peptic ulcer, psychosis, active or suspected TB, acute infection, or documented hypersensitivity or allergy to dexamethasone~* Pregnancy (confirmed by a serum human chorionic gonadotropin pregnancy test) or breast feeding
