Chronic disability caused stroke

Stroke is a global health problem affecting approximately 750,000 people annually in the United States alone and ranks as the third leading cause of death and the most common cause of disability in most developed countries. Traumatic brain injury (TBI) accounts for an estimated 34% of all injury-related deaths in the United States. Stroke and TBI can produce both focal and widespread damage to the brain, which can yield acute and chronic impairments of sensory, motor, and cognitive functions. Because of their enormous medical and socioeconomic impact, a tremendous research investment is being made in the treatment and prevention of stroke and TBI.
