Subdural hematoma causes
A subdural hematoma occurs when an injury occurs in the brain’s blood vessel (the subdural space). When blood leaks from the blood vessel, a blood clot (hematoma) forms, putting pressure on the brain and harming it.
Subdural hematomas are frequently the result of severe head injuries, such as those suffered in a violent attack, fall, or vehicle accident.
However, mild head bumps can result in a subdural hemorrhage in a few instances.
If you are older than 60, taking blood-thinning medication, or have a history of alcohol abuse, a mild head injury is more likely to result in a subdural hemorrhage.
How to treat subdural hematomas
The most effective course of treatment for subdural hematoma is typically surgery.
The two most popular surgical procedures for treating:

- In craniotomy, the surgeon temporarily removes a portion of the skull to access and remove the bleeding
- Burr holes are small holes drilled, placing a tube into the head to help drain the hemorrhage
You must consider minor subdural hemorrhages to see if they go away without surgery.
