Abstract
Introduction: Chronic subdural hematoma (CSDH) is a common neurosurgical disease, whose incidence has been steadily increasing with our aging population. While not common, CSDH can also occur in children. CSDH is often associated with traumatic head injury, but its underlying mechanism remains poorly understood. The first line treatment for CSDH is surgery. However, surgery is contraindicated in some patients and has a high rate of recurrence. Effective non-surgical treatment is therefore highly desirable.Areas covered: This review discusses the pathogenesis of CSDH and drugs that have been used to treat CSDH either as monotherapy or an adjuvant to surgery, including controlled clinical trials.Expert opinion: The pathophysiology of CSDH remains poorly understood. Developing effective drug treatments is therefore challenging. Most drugs discussed in this review are evaluated in small clinical studies without sufficient sample size and controls for confounding variables. More controlled clinical trials are therefore needed to carefully evaluate drugs for the non-surgical treatment of CSDH, especially for drugs targeting specific pathogenic pathways of CSDH.
