An epidural hematoma is a type of brain injury that occurs when blood collects between the outer layer of the brain, called the dura mater, and the skull. This condition is often caused by a head injury, such as a fall or a car accident, which can tear blood vessels and lead to bleeding. Symptoms may include headache, confusion, dizziness, and loss of consciousness. If not treated promptly, an epidural hematoma can increase pressure on the brain, leading to serious complications. Diagnosis typically involves imaging tests like a CT scan or MRI. Treatment often requires surgical intervention to remove the accumulated blood and relieve pressure.
