Cerebral vascular accidents, commonly referred to as strokes, occur when blood supply to a portion of the brain is interrupted or severely reduced. This deprives brain tissue of oxygen and nutrients, leading to cell damage and potentially long-term neurological deficits. There are two primary types: ischemic, caused by a blockage of an artery supplying the brain, and hemorrhagic, resulting from the rupture of a blood vessel within or on the surface of the brain.
Understanding the factors that contribute to these events is crucial for preventative measures and risk management. Identifying and addressing modifiable risk factors can significantly decrease the incidence and impact of strokes. Historical context reveals an evolving understanding of vascular disease and the development of therapies aimed at reducing its devastating effects. This knowledge empowers individuals to take proactive steps toward safeguarding their brain health.
