Chronic subdural hematoma presenting as headache and cognitive impairment after minor head trauma.

Although relatively uncommon, a chronic subdural hematoma carries a high incidence of morbidity and potential mortality. An aging population combined with an increased usage of anti-platelet and anticoagulation drugs enhances the likelihood that physicians will encounter this condition in routine practice. A heightened index of suspicion, coupled with a thorough clinical and diagnostic examination, is necessary to uncover this sometimes indolent problem. This case study highlights the presentation of an unusual case and discusses the diagnosis, evaluation and treatment of chronic subdural hematomas.
