Subdural Hemorrhage

A subdural hemorrhage is a collection of blood between the brain’s surface and its outer protective covering (the dura). It’s most often caused by head trauma, though it can also occur spontaneously, particularly in older adults or those on blood-thinning medication.

Signs & Symptoms

Symptoms can include headache, confusion, drowsiness, weakness on one side of the body, or, in severe cases, loss of consciousness. In older adults, symptoms may develop slowly over days to weeks after a minor injury.

Causes & Risk Factors

Head injury is the most common cause. Risk increases with age, blood-thinning medications, and a history of falls.

Diagnosis

Diagnosis is made with CT or MRI imaging of the brain.

Treatment Options

Small subdural hemorrhages may be monitored closely. Larger ones often require surgery to drain the blood and relieve pressure on the brain; some cases are treated with a minimally invasive procedure called middle meningeal artery embolization.
