Subdural hemorrhage
Subdural Hemorrhage
Subdural Hemorrhage (pronounced: sub-doo-ral hem-or-ij) is a type of intracranial hemorrhage that occurs beneath the dura mater, one of the layers of tissue between the brain and the skull. It is often caused by trauma to the head, and is characterized by the collection of blood between the dura and the arachnoid mater.
Etymology
The term "Subdural Hemorrhage" is derived from Latin roots. "Sub" means under, "dura" refers to the dura mater, and "hemorrhage" is derived from the Greek words "haima" (blood) and "rhegnynai" (to burst forth).
Causes
Subdural Hemorrhage is most commonly caused by head injury, particularly in older adults and young children. Other causes can include anticoagulant medication, alcohol abuse, and cerebral atrophy.
Symptoms
Symptoms of Subdural Hemorrhage can vary depending on the severity of the hemorrhage, but may include headache, dizziness, nausea, vomiting, loss of consciousness, and neurological deficits such as weakness or numbness on one side of the body.
Diagnosis
Diagnosis of Subdural Hemorrhage typically involves a neurological examination and imaging tests such as a CT scan or MRI.
Treatment
Treatment for Subdural Hemorrhage can range from observation for minor cases to surgical intervention for more severe cases. This may involve a craniotomy to remove the blood and relieve pressure on the brain.
