[Presentation of chronic subdural hematoma in the elderly].

A 87-year old man was admitted to our hospital with decline in cognition and mobility and visual hallucinations. CT scanning revealed a bilateral chronic subdural hematoma. The hematoma was probably caused by a recent fall, while the patient was using acenocoumarol. Chronic subdural hematoma (CSDH) is a frequently occurring intracranial bleeding in the elderly. It usually occurs after a minor trauma and may present with a variety of symptoms. The differentiation between CSDH and other disorders like dementia can be difficult when the hematoma presents with cognitive decline and neuropsychiatic symptoms, such as hallucinations.
