The most common cause for a subdural hematoma is head injury.This can be from a car crash, fall, or violent attack.A subdural hematoma is a buildup of blood on the surface of the brain. It's a tough, fibrous layer called the dura mater, or usually just dura. In a subdural hematoma, the blood seeps between the dura and the arachnoid layers. This bleeding often comes from a blood vessel that breaks within the space around the brain. Older adults are at higher risk for a subdural hematoma, even with mild head injury.The blood builds up in a space between the protective layers that surround your brain. Inside your skull and over the brain there are 3 layers called the meninges. On the inside of the dura is a layer called the arachnoid. Cerebrospinal fluid (CSF) fills the space inside the meninges. This is because the veins surrounding the brain are more likely to tear.Doctors generally do a CT scan or a MRI of your head to look for signs of bleeding.It is very important to find the site of the bleeding.This sudden impact can strain the blood vessels within the dura, causing them to rip and bleed.
The imaging of subdural hematoma has evolved significantly.In some people, the brain shrinks (often from aging) and the subdural space gets bigger.This can make the blood vessels more likely to break.Acute subdural hematomas are often life-threatening. Chronic subdural hematomas have a better prognosis if properly managed.In contrast, epidural hematomas are usually caused by tears in arteries, resulting in a build-up of blood between the dura mater and the skull.
