Classification Strokes occur when the blood supply to a part of the brain is interrupted. They are considered with cerebrovascular disease for classification of mortality only when they are not the result of trauma. The onset of symptoms for epidural and particularly subdural hematomas is generally more gradual than that of stroke. The onset of symptoms is sudden and subarachnoid hemorrhages are often considered a type of hemorrhagic stroke. Risk Factors Risk factors are personal characteristics and behaviors that increase the chances of getting a particular disease.
Stroke occurs in all age groups even infants.
In 1998,there were 26 fatal strokes in Indiana residents less than 35 years old. However, the risk of stroke more than doubles for each ten years of life after age 55. Thus, men die from stroke on average at a younger age than women do. African-Americans have a much higher risk of dying from a stroke than do white Americans. The risk of stroke is also higher for Hispanics.
