What's the difference between ischemic stroke, hemorrhagic stroke, and embolic stroke?

Pathophysiology: Ischemic stroke occurs when an artery to the brain is blocked.A thrombotic stroke occurs when diseased or damaged cerebral arteries become blocked by the formation of a blood clot within the brain. An embolic stroke is also caused by a clot within an artery, but in this case the clot (or emboli) forms somewhere other than in the brain itself. Hemorrhagic stroke is sudden bleed into the brain. ...Read more

Maybe potential stroke risk, especially lacunar infarct, but not straightforwards. Your physician needs to assess stroke risk. Spots more likely from migraine or prior injury. ...Read more

What's the difference between a cerebral vascular accident (stroke) & a transient ischaemic attack (tia)?

Definitive damage: A TIA describes stroke like symptoms that resolve without other intervention within a short timespan, usually less than 1 hour although the classic definition uses 24 hours. A stroke describes irreversible brain tissue damage caused by a lack of blood flow (technically a bleed is also a form of stroke).

What are the differences between a stroke or mini stroke ?

Dr. Irv Loh Dr. Loh
1 doctor agreed:

Reversibility: Mini-strokes are colloquially thought of as transient ischemic attacks, or tias, which are neurologic deficits that may resolve over a relatively short period of time. This is in contrast to a typical full blown stroke that does not resolve, though may improve with hypothermia, medications including possibly lytic therapy (if a candidate) or revascularization procedures. ...Read more

Depends: This is a complex question. It depends on what percent of is already showing signs of infarction (dead brain) rather than just ischemia (brain at risk).... When we see > 1/3 of territory abnormal on initial ct scan, it is a contraindication for tpa (alteplase). It also depends on how long the symptoms have been occurring. But to answer your question, theoretically all could potentially benefit. ...Read more
