  • Subdural Hematoma (Acute)

Subdural Hematoma (Acute)

Overview

This condition is a buildup of clotted blood between the brain's outer layer and the membrane that covers the brain (called the dura). It usually results from a traumatic impact to the head, such as from a fall or car accident.

How it Forms

When the head receives a violent blow, blood vessels between the skull and the brain can stretch and tear.

Hemorrhage

Leaking blood becomes trapped beneath the dura, forming a pool on the surface of the brain. Less commonly, a clot can form after an artery on the brain's surface spontaneously bursts.

Symptoms

A small blood clot may go unnoticed, but a large clot can press harmfully against the brain. It can cause a range of symptoms, including confusion, severe headaches, lethargy, nausea, slurred speech and seizures.

Treatment

An acute subdural hematoma is an emergency condition, and should be treated quickly to prevent permanent brain damage. Treatment options include medications to control the swelling and/or seizures and surgery to open the skull and drain the clot.
