Transient Ischemic Attack (Mini Stroke) (Definition)
A condition where a blood vessel in the brain is temporarily blocked by a blood clot, causing neurologic symptoms such as weakness in an arm or leg, or sensory changes.The symptoms are similar to those from a stroke, but are temporary, disappearing within minutes after the clot breaks apart. ...Read more
TIA or STROKE: Tia or stroke are due to atherosclerosis of carotid arteries, or clot coming from heart. The majority of these processes happens in people with high blood pressure or diabetes. Both of these diseases has some genetical components. Several other reason people develop stroke like, smokers, in people with cancer, or autoimmune diseases. Most of those reasons has some genetic components. ...Read moreSee 1 more doctor answer
Possible: TIA can present as suddenly decreased vision ("curtain falling" or blurred vision). It can be in one eye or in both eyes (in which case it is usually only on one side of vision). Many other diseases can cause blurry vision - migraines, problems with the eye itself. ...Read moreSee 1 more doctor answer
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
I had a brain MRI yday to look for ischaemia due to symptoms . TIA is suspected. If this doesnt cause permanant changes how do they know i had a TIA?
Usually not: The differential diagnosis for "spots" in your vision is varied with the most common cause being floaters secondary to a vitreous detachment. Other causes include orthostatic hypotension changes, ocular migraines, vitreous hemorrhage, and retinal detachment. It is important to get other associated symptoms such as flashes of light. A stroke/tia usually results in total vision loss or greying. ...Read more
Is a PFO just a diagnosis of exclusion for stroke/tia seeing as 25% of population have it anyway or is it a real risk and needs to be closed ?
Possible: It is possible to develop a stroke during carotid stent placement (~ 4% in optimal patients). However the carotid stent is effective at preventing further strokes and that is why they are placed. At this point carotid stents are reserved for patients who are at high risk for open carotid endarterectomy (surgery). ...Read moreSee 3 more doctor answers
See below: Thorough neurologic examination is the first step in diagnosing a stroke or tia. A neurologist may develop concern based on typical neurologic defecits. If indicated, MRI is the best test for identifying or ruling out a stroke. If the symptoms are similar to a stroke but there is no stroke on MRI and/or the symptoms resolve, it is more likely to have been a transient ischemic attack (tia). ...Read moreSee 1 more doctor answer
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
Yes: The short answer is yesGet a more detailed answer ›
Yes: If you have failed medical management and are high risk for surgery, then carotid angioplasty and stenting with distal protection should be considered. Find an experienced operator and the risk of stroke during the procedure can be as low as 1%, which rivals surgery results. I have been doing carotid stents since 1999 and this procedure has helped many of my patients. ...Read moreSee 2 more doctor answers
I had sudden hearing loss in r ear, dizzy, sick, num in arm and leg hosp said TIA test to follow. Can this happen again when waiting for tests?
Depends on cause: Sudden hearing loss, vertigo and nausea are a triad that occur with injury to the auditory nerve/inner ear. It is unlikely to be a TIA which implies blood clot in the brain. Severe sx are generally from injury directy to the nerve - viral infection is often the cause. The arm & leg should not be involved. If they are, TIA is more likely and could recur if not treated. (antiplatelet drugs or surg). ...Read more
Several tests: There is no test that makes the diagnosis of a TIA, but if someone comes to the hospital with a TIA, they should have these tests: head CT without contrast echocardiogram EKG blood tests (CBC and electrolytes, blood sugar, cholesterol) carotid artery ultrasound Sometimes other tests are important too. This is just a guide. ...Read moreSee 3 more doctor answers
