See comments: Are you referring to radiology reading of an MRI of brain? In elderly, often thought that white matter lesions are associated with "microvascular angiopathy", sign of potential atherosclerosis. 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
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
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
Acute - Sudden Onset: Acute stroke refers to a stroke that has just occurred. Ischemic stroke may be hyperacute (based on sudden onset neurological symptoms and imaging findings, MRI and perfusion study) and potentially treatable, acute (1-7 d), subacute (7-21 d), and chronic (>21 d). ...Read moreSee 1 more doctor answer
Complex issue: Transients events can be due to heart defects, arrhythmia, blood pressure, blood sugar, drug effects, seizure, migraine, or blood vessel disorders. It would be important to have a thorough medical and neurological evaluation. Their may be genetic factors involved, especially defects in cholesterol and lipid metabolism. May be a high risk for completed stroke or even death. ...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). This damage can be diagnosed definitively on a MRI scan, no such damage can be seen in the tia. ...Read moreSee 2 more doctor answers
Potentially yes: Most ischemic strokes such as thrombosis or embolism cause significant damage but not immediate fatality. However, intracranial hemorrhage has a 60% mortality within one year, and a ruptured aneurysm causes death in 50% prior to reaching a hospital. The garden variety stroke in certain parts of brain have potential for death depending upon extent. ...Read more
66yr/ m congestive heart failure, stroke, pulmonary embolism, then 2nd massive hemorrhagic stroke, surgery to repair, fell into coma. prognosis?
Elderly lady had stroke due to blood clot. Has brain swelling. In a coma. Stroke induced. Chances of survival?
See below: Am not familiar with "unspecified", but transient cerebral ischemia means diminished blood flow to a part of the brain causing clinical symptoms. Since this can be the first sign of an impending stroke, this needs to be fully evaluated and medication started for prevention. See a neurologist and get this fully addressed. ...Read moreSee 1 more doctor answer
Cardiac Stroke: A blood clot that starts in the heart (usually a bad valve, irregular heart beat causing pooling in the heart, or heart attack with damaged heart tissue) and travels to the brain causing a stroke (cerebral vascular accident). Treatment is based on thinning the blood to prevent another event and if caught soon enough (usually within 3-6 hours), blood clot dissolving therapy. ...Read more
You mean a TIA: Transient ischemic attack (TIA) is often called a "mini-stroke, " and is considered a harbinger for a full-blown stroke. It can occur as a result of a narrowing in the carotid arteries. Unlike a stroke, TIA symptoms last anywhere from 15 minutes to 24 hours. Typically can present with blindness to one eye, paralysis, or slurred speech. You should see a vascular surgeon immediately. ...Read moreSee 1 more doctor answer
