3The brain is an extremely complex organ that controls various body functions.If a stroke occurs and blood flow cant reach the region that controls a particular body function,that part of the body wont work as it should.If the stroke occurs toward the back of the brain,for instance,its likely that some disability involving vision will result.The effects of a stroke depend primarily on the location of the obstruction(阻塞)and the extent of brain tissue affected.
4The American Stroke Association has identified several factors that increase the risk of stroke.The more risk factors a person has,the greater the chance that he or she will have a stroke.Some of these you cant control,such as increasing age,family health history,race,and prior stroke.But you can change or treat other risk factors to lower your risk.Factors resulting from lifestyle or environment can be modified with a healthcare providers help.Some of these include:high blood pressure,current smoking,heart disease,and high red blood cell count.
5A stroke can happen to anyone at any moment.In fact about 600,000 people have strokes every year.For many years,there was no hope for those suffering a stroke.However,recent breakthroughs have led to new treatments.For the treatments to work,the person must get to a hospital immediately.
