A subdural hemorrhage is caused by bleeding that takes place due to the rupture of one or more of the blood vessels (typically veins) that travel in the subdural space, located between the surface of the brain and the ‘dura’, a thin layer of tissue that separates the brain from the skull.

Commonly this type of hemorrhage is caused by trauma to the head, although it can also arise spontaneously, especially in the elderly.

Subdural hemorrhages can become large enough that they push against the brain, and cause a stroke. In the most severe cases, they can even lead to death.

What is Stroke?

Stroke is a disease that affects the arteries leading to and within the brain. It is the No. 5 cause of death and a leading cause of disability in the United States. A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts (or ruptures). When that happens, part of the brain cannot get the blood (and oxygen) it needs, so it and brain cells die.

Effects of Stroke

The brain is an extremely complex organ that controls various body functions.  If a stroke occurs and blood flow can't reach the region that controls a particular body function, that part of the body won't work as it should. 

Risk Factors of Stroke

  • Age — The chance of having a stroke approximately doubles for each decade of life after age 55. While stroke is common among the elderly, a lot of people under 65 also have strokes.
  • Heredity (family history) — Your stroke risk may be greater if a parent, grandparent, sister or brother has had a stroke. 
  • Race — African-Americans have a much higher risk of death from a stroke than Caucasians do. This is partly because blacks have higher risks of high blood pressure, diabetes and obesity.
  • Sex (gender) — Each year, women have more strokes than men, and stroke kills more women than men. Use of birth control pills, pregnancy, history of preeclampsia/eclampsia or gestational diabetes, oral contraceptive use, and smoking, and post-menopausal hormone therapy may pose special stroke risks for women. 
  • Prior stroke, TIA or heart attack — The risk of stroke for someone who has already had one is many times that of a person who has not. Transient ischemic attacks are "warning strokes" that produce stroke-like symptoms but no lasting damage. TIAs are strong predictors of stroke. A person who's had one or more TIAs is almost 10 times more likely to have a stroke than someone of the same age and sex who hasn't. Recognizing and treating TIAs can reduce your risk of a major stroke. TIA should be considered a medical emergency and followed up immediately with a healthcare professional. If you've had a heart attack, you're at higher risk of having a stroke, too.
