Chronic subdural hematoma (CSDH) is defined as a collection of blood in the subdural space for more than 21 days. The most common cause of CSDH is trauma, which is usually considered as a minor trauma. Dementia, coagulation defects, heavy alcohol use, infancy, and age are major risk factors for the development of CSDH. On the other hand, electroconvulsive therapy (ECT) is not among the major risk factors, but there are several case reports of CSDH following ECT reported in the literature. Based on these reported cases, clinicians should consider the possibility of CSDH in high-risk psychiatric patients during and after ECT.
