Conditions and Treatments
A stroke occurs when the blood vessel that carries oxygen and nutrients to the brain is either blocked or bursts. When that happens, the region of the brain deprived of oxygen or nutrients doesn't work properly.
Risk factors include being over 55, being male, having a family history of stroke, being African American or having previously had a stroke. Other factors include smoking, having high blood pressure and other heart-related diseases.
Tests & Treatment
There are many tests that can be done to diagnose stroke, and treatment includes clot-busting medications. However, people who suspect they are having a stroke need to obtain medical attention with three hours for this medication to be effective.
