There are two types of stroke – ischemic and hemorrhagic.

A stroke is a medical emergency, and prompt treatment is crucial. Early action can reduce brain damage and other complications.

  • An ischemic stroke is the more common type of stroke. It’s also referred to as brain ischemia and cerebral ischemia.
  • Causes – It is usually caused by a blood clot that blocks a blood vessel in the brain. This interrupts or reduces blood from flowing to the brain.
  • This, in turn, will prevent brain tissue from getting oxygen and nutrients. Brain cells begin to die in minutes.
  • Another cause is stenosis, or narrowing of the artery.
  • This can happen because of atherosclerosis, a disease in which plaque builds up inside your arteries.
  • Transient ischemic attacks (TIAs) also known as a ministroke, occur when the blood supply to the brain is interrupted briefly.
  • Having a TIA can mean you are at risk for having a more serious stroke.
  • Symptoms – Trouble speaking & understanding what others are saying.
  • Paralysis or numbness of the face, arm or leg.
  • Problems seeing in one or both eyes.
  • A sudden, severe headache, which may be accompanied by vomiting, dizziness or altered consciousness.
  • Trouble walking
