What Is a stroke?
A stroke is a “brain attack.” A stroke is a condition that occurs when a blood clot blocks a blood vessel or when a blood vessel ruptures, interrupting blood flow to the brain. This leads to destruction of brain cells in the immediate area where blood flow is compromised within minutes. In fact, during a stroke, 2 million brain cells die every minute.
A chemical reaction occurs that also endangers cells in the surrounding area where blood flow is limited, but not completely stopped. These cascading events occur rapidly, creating a limited amount of time for effective treatment. When brain cells die, normal bodily functions controlled by the dying brain are lost.
Therefore, it is critical for stroke victims to obtain emergency treatment aimed at re-establishing blood flow and reducing the amount of damage from stroke. Time is brain. Every second counts in minimizing the amount of brain function that can be lost due to stroke.
