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 a stroke, but are temporary, disappearing within minutes after the clot breaks apart. ...Read more
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 more
I had a brain MRI yday to look for ischaemia due to symptoms. TIA is suspected. If this doesn't 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?
Yes and no: Yes its an exclusionary diagnosis. No real good evidence that closure is beneficial. A recent study published in new england journal of med. Noted no real benefits. ...Read more
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 more
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
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
blood tests (CBC and electrolytes, blood sugar, cholesterol)
carotid artery ultrasound
Sometimes other tests are important too. This is just a guide. ...Read more
Unlikely: It is unlikely. Tia causes short-term decrease in brain function which usually results in a deficit which is easily detected/observable - weakness, numbness, speech disturbance, visual deficit etc. It is unlikely to have a TIA and not know it. ...Read more
I don't masturbate this liquid sometimes clear sometimes white comes out when I pee. Then my scrotum hurts what does it mean? Tia
Here are some. ..: The pertinence & relevance in the question aren't clear to pointedly answer your question. Nonetheless, I would try. Seeing clear urethral discharge may occur after some sexual arousal without masturbation or after straining during bowel movement. If additionally also feeling some urethral stinging, be checked for STD. For scrotal hurt, Doc needs to analyze its onset, degree, duration. .. ...Read more
TIA: Treated with Aspirin or aggrenox. Of course it needs full evaluation before treatment. ...Read more
Healthy lifestyle: General recommendation is to control blood pressure, cholesterol levels, glucose levels (if diabetic), adhere to a healthy diet (mediterranean is great!), quit smoking and be physically active (at least 30 minutes per day 3 times a week). Aspirin is commonly used as a first medication unless there is an indication for a blood thinner. ...Read more
Even if you apply the older criteria
to define a tia, all of your symptoms should have resolved in 24 hours. Using the currently accepted criteria, your symptoms should have resolved in one hour. If you continued to have objective findings weeks-> months out, you had a stroke. ...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 more
Ischemic stroke at 90, pelvic fracture and cerebral contusion at 92. If risk of bleeding from falling > risk of tia/stroke from clot, baby aspirin ok?
Judgement: There's no answer to your question. No one has collected a series of 5, 000 people like you and tested the two options. This is where having a doctor whom you trust and who knows your history and all about you makes all the difference. (your question exemplifies why computers are never going to be able to practice medicine!). ...Read more
TIA: Some one can have series of TIA but still can survive. The definition of TIA is symptoms last less than 24 hours and will have full tecovery. ...Read more
Absolutely: Someone who is having tias should most definitely have their carotids checked since the carotid arteries are the number one source for embolic strokes. In "symptomatic" patients, such as someone who is having tias, a carotid blockage of 50% or more warrants intervention. ...Read more
Rare but possible: Vasospasm in the brain occurs when blood and its breakdown products are present in the spinal fluid around blood vessels. The most common reason is rupture of brain aneurysm, but there are other conditions. Vasospasm causes the larger vessels (arteries, arterioles) to clamp down or contrict, thus reducing blood flow. This can cause strokes or tias. ...Read more
I suppose so: Strokes and tias are, at their underlying cause, basically the same thing. Both involve clots impairing blood flow to brain cells. Tias are just when the clot fortunately dissolves in enough time such that no permanent damage has occurred. Oranges are in general probably good and better than foods with high salt, fat, sugar or cholesterol content. ...Read more
Stroke prevention: Optimal stroke prevention depends on minimizing risk factors, whether a person is outdoors or not. If there is no carotid artery disease, then risk factor modification includes keeping a healthy blood pressure, blood sugar, cholesterol, no smoking, and taking special medication if there is a heart rhythm irregularity called atrial fibrillation. ...Read more
What can be done for stroke prevention for someone who is having tias but is very active outdoors?
Not enough information to even begin...
First things first:
overweight? High blood pressure? Smoking? High cholesterol?
Active outdoors doesn't help... If you have high blood pressure and be "active" may actually endanger you (if you have high blood pressure it goes up even higher during exercise). ...Read more
If a lesion is a scar from a past stroke 6 months to a year ago and foci resolves and appears in new locations would foci likely be from tias?
Scar if you ment in mri, does not go away.
If you do not see it in new mri, it is because it is very small and it might be between MRI "slices."
the new foci in your age, would be very unusual to be due to TIA if you do not have risk factors such as diabetes or high blood pressure.
A neurologist can work with you to make sure you are not suffering from multiple sclerosis. ...Read more
I have chiari, &i haven't been feeling well. Admitted last week 3 prev. Tias the back of my head in tingling. I had surg 3 yrs ago. Should I be worried?
You are describing symptoms that are not typical of chiari malformations, before or after surgery. You have adrenal insufficiency, which can cause fatigue, nausea, GI symptoms.
Check with your doctor to see if your symptoms are more consistent with adrenal insufficiency. If necessary, brain MRI can rule out abnormalities in the brain after chiari surgery. ...Read more
90 with tia and spee: If you are ninety and with history of tia, you should consult your neurologist or family doctor asap, or go to er, as you may be having a stroke. ...Read more
