What Is a Stroke?



Strokes are the third leading cause of death and a leading cause of disability among Americans.

What Is a Stroke?

A stroke is also called a “brain attack” because like a heart attack, it results from a blockage in blood flow to the organ, according to the University of Maryland Medical Center. Identifying a stroke’s signs and getting immediate help are critical to minimizing damage and preventing death; the longer blood is cut off, the more damage is done. How a stroke affects someone depends on what part of the brain is deprived of blood. Different limbs or abilities, such as speech, could be affected.

Dulcinea's Insight

  • If you believe someone is experiencing a stroke, call 911 immediately. When someone is having a stroke, quick treatment is essential to preventing long-term damage.
  • A stroke can also occur when a blood vessel breaks and leaks into the brain, which also interrupts blood flow.
