Updates on the diagnosis and management of subdural hematoma.

Abstract: Intracranial hemorrhage is a potentially life-threatening condition categorized into four main groups by the location of bleeding: epidural, subdural, subarachnoid, and intraparenchymal. Subdural hematoma (SDH) is increasingly common as the population of older adults increases. Clinicians must recognize the typical presentations and order diagnostic imaging studies to make a timely diagnosis and referral to neurosurgery for definitive treatment. Understanding the pathophysiology and risk factors for chronic or expanding SDH informs decision-making in managing anticoagulants. Emerging treatments offer potential alternatives to the traditional evacuation of SDH by craniotomy, which remains the standard of care for most symptomatic patients.
