Define stroke. Describe the differences between ischemic and hemorrhagic strokes
What will be an ideal response?
• Stroke is defined as a disruption of brain function caused by interruption of blood flow to the brain.
• Ischemic stroke refers to a reduction in blood flow caused by atherosclerotic or damaged blood vessels that supply blood to the brain. A thrombotic stroke may also result via a plaque breaking off and occluding an already narrowed vessel.
• Hemorrhagic stroke results from a weakened blood vessel that ruptures and bleeds into the surrounding brain; blood accumulates and compresses surrounding brain tissue.
