Questions and Answers

How do embolic ischemic strokes differ from thrombotic ischemic strokes?

  • Emboli form elsewhere in the body before reaching the brain (correct)
  • Emboli form directly in the cerebral artery
  • Thrombi are caused by genetic factors
  • Thrombi cause immediate symptoms
  • What is the cause of ischemic strokes?

  • High blood pressure
  • Viral infection
  • Local thrombus formation (correct)
  • Genetic predisposition
  • What is the consequence of ischemic stroke on cerebral blood flow?

  • Increasing cerebral blood flow causing ischemia and infarction
  • Decreasing cerebral blood flow causing ischemia and infarction (correct)
  • No effect on cerebral blood flow
  • Causing hemorrhage in the brain
  • Study Notes

    Types of Ischemic Strokes

    • Embolic ischemic strokes occur when a blood clot or plaque fragment breaks loose and travels to the brain, blocking a blood vessel.
    • Thrombotic ischemic strokes occur when a blood clot forms in a blood vessel in the brain, blocking blood flow.

    Causes of Ischemic Strokes

    • Ischemic strokes are caused by a blockage in a blood vessel that supplies blood to the brain, resulting in inadequate blood flow and oxygen delivery to brain tissue.

    Consequences of Ischemic Strokes

    • Ischemic strokes lead to a reduction in cerebral blood flow, causing inadequate oxygen delivery to brain tissue, which can result in tissue damage or death.
