	Chronic subdural hematoma
		Chronic subdural hematoma develops when veins that are located between the membranes covering the brain slowly leak blood after a head injury.
		Chronic subdural hematoma may be diagnosed after the health care provider has ruled out other possible causes (such as intracerebral hemorrhage) of decreased mental functioning and other symptoms after a history of head injury.
		Recurrent chronic subdural hematoma is common and occurs in approximately 30% of individuals treated for chronic subdural hematoma.

	Subdural hematoma \| Topic Definition \| Find the Meaning and Define the Answer of Subdural hematoma
		A subdural hematoma, also called a subdural hemorrhage, is a collection of blood between the dura (the outer protective covering of the brain) and the arachnoid (the middle layer of the meninges).
		Subdural hematomas are most often caused by head injury, when rapidly changing velocities within the skull may stretch and tear small bridging veins.
		Subdural hematomas are divided into acute, subacute, and chronic, depending on how quickly or slowly they take to form.
