Stroke, often called a Cerebrovascular Accident (CVA), is a sudden central nervous system impairment in which the flow of oxygen and nutrients to the brain is halted through a blood clot (ischemia) or bleeding (hemorrhage). It is the third leading cause of death in the United States and the leading cause of disability. Four million stroke survivors are living in the United States, and more than 730,000 Americans experience a stroke each year. An individual who has experienced a stroke can have a wide range of limitations from minimal to severe. The side of the brain where the stroke took place controls the opposite side of the body. So if an individual experiences a stroke on the left side of their brain the right side of their body will most likely be effected. Individuals can experience a number of secondary conditions as well including paraplegia, hemiplegia, decreased balance, and speech and memory issues to name a few.
