Stroke is one of the leading causes of death that occurs due to interrupted or severely reduced blood supply to a part of the brain. This interruption in blood supply can be either due to a blocked or ruptured blood vessel within the brain that deprives oxygen and nutrients supply to the brain tissue. Eventually, brain cells begin to die, arising a medical emergency that needs treatment as quickly as possible to prevent potential complications.


There are three main kinds of stroke:

  1. Ischemic strokes
  2. Hemorrhagic strokes
  3. Transient ischemic attacks (TIAs), also referred to as mini-strokes

Causes of Stroke

  • Ischemic stroke occurs due to a blocked or narrowed artery
  • Hemorrhagic stroke occurs due to leaking or bursting of a blood vessel
  • Transient ischemic attack, or TIA occurs due to temporary disruption of blood flow to their brain
