Hemorrhagic Conversion Of 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
It's possible: Aphasia (inability to speak or understand speech) is caused by damage (ischemia or hemorrhage- bleeding) to certain parts of the brain (usually on the left brain for right handed patients) that control speaking and understanding speech. Tumors in those areas can also affect speech. ...Read moreSee 1 more doctor answer
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
Elderly lady had stroke due to blood clot. Has brain swelling. In a coma. Stroke induced. Chances of survival?
That's irrelevant: You're making a common layperson's mistake: You're confusing a correlative marker with the thing itself. The presence of cerebral atrophy either during life in imaging or pathologically after death tells you nothing by itself. What matters is how well a brain WORKS, not how it looks. It doesn't really matter how the brain of someone in PVS looks. What matters is the PVS. A fate worse than death. ...Read moreSee 1 more doctor answer
Matter of size: A lacunar stroke is due to a block in a smaller end artery, as contrasted to a carotid or middle cerebral artery obstruction, which would cause damage to a larger area of brain. Many strokes in the basal ganglia are small and often not noticed clinically, but the larger ones are very evident. ...Read moreSee 1 more doctor answer

CIS vs MS vs stroke: You have a demyelinating lesion in the back part of your corpus callosum . This can be due to MS , clinically isolated syndrome or something else. Your ability to process vision may be affected. I do not have enough information to comment on the abnormal blood count. Based on what has been ordered it appears that you are in good hands. ...Read more
Several: A stroke that affects broca's area in the dominant hemisphere will affect expressive speech and possibly comprehension. This can be due to ischemic stroke eg a plaque rupture and/or blood clot, hemorrhagic (bleeding) or embolic (drifting blood clot) types of stroke. A stroke of other (posterior) areas may garble the speech but not affect language otherwise. ...Read moreSee 2 more doctor answers
Prevention: Anticoagulation used to prevent stroke; there's little evidence it helps treat stroke. In fact, use of full anticoagulation w stroke risks brain bleeding & worsening the stroke. "Full" anticoagulation (warfarin, coumadin, Xarelto, Eliquis, Pradaxa, Savayasa) used to prevent stroke in patients with atrial fibrillation; for other causes Aspirin, Plavix & similar antiplatelet used for prevention. ...Read moreSee 2 more doctor answers
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
Limited: This particular agent is only given subcutaneously so its use is pretty much limited to, if we just focus on atrial fibrillation here, those patients who cannot take an oral anticoagulant but are felt by their doctors to be at high risk for an embolic stroke or event in the setting of atrial fibrillation. There are oral medications that have similar mechanisms of action and validated efficacy. ...Read more
They haven't paid up: Until they they go through untrackable bribing process and get the indication, just have to use unofficially. ...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
