Differentiate between ischemic stroke, hemorrhagic stroke, and transient ischemic stroke.
Understand the Problem
The question is asking for the differences between three types of strokes: ischemic stroke, hemorrhagic stroke, and transient ischemic stroke. The answer will likely involve explaining the causes, symptoms, and medical implications of each type.
Answer
Ischemic stroke: blockage; Hemorrhagic stroke: bleeding; TIA: temporary blockage (mini-stroke).
An ischemic stroke is caused by a blockage in an artery that supplies blood to the brain. A hemorrhagic stroke occurs when a blood vessel in the brain ruptures, causing bleeding. A transient ischemic attack (TIA) is a temporary disruption of blood flow to the brain, often called a "mini-stroke."

An ischemic stroke is caused by a blockage in an artery that supplies blood to the brain. A hemorrhagic stroke occurs when a blood vessel in the brain ruptures, causing bleeding. A transient ischemic attack (TIA) is a temporary disruption of blood flow to the brain, often called a "mini-stroke."
More Information
Most strokes (about 85%) are ischemic. Hemorrhagic strokes can be further categorized into intracerebral hemorrhage and subarachnoid hemorrhage. TIAs usually resolve on their own within minutes but are serious warning signs of potential future strokes.
Tips
A common mistake is confusing a TIA with a full stroke due to their similar symptoms; however, TIAs are temporary and do not cause permanent damage.
