Unspecified Transient Cerebral Ischemia
Tia (transitory ischemic attack) happens when blood supply to a certain area of the brain gets cut off temporarily. This causes a neurologic deficit - weakness, numbness, visual deficit or difficulty with speech. While TIA usually resolves, it indicates that there is a problem with your heart or blood vessels that can cause ...Read more
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 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 more
So complicated: In short, no - migraines are not a hypoperfusive state. The old (not correct) understanding in fact was based on the observation that blood flow often increases with migraines. Like all things in the body, our understanding now is much more complicated. There's a complex interaction between the neurons (primary problem) and the vessels and surrounding structures (secondary). ...Read more
Decreased blood flow: The classic is transient ischemic attack (tia), brief decreased blood flow to a small area of brain which can be the first sign of stroke risk. Blood flow issues may play a minor role in migraine, and low blood pressure may diffusely drop cerebral blood flow. Treat the many risks, diabetes, hypertension, high blood fats, hyperhomocysteinemia, carotid stenosis. Anti-platelet drugs protect. ...Read more
No role: I am not aware of any role for cyclic amp in the treatment of any brain disorder, but of course, it is important in cellular metabolism. ...Read more
Prevention: After a TIA or even stroke, the next greatest risk, over next year is another stroke. The protocol often used includes aggenox and lipitor (atorvastatin). Need to make sure however, that you do not have carotid stenosis, and that hypertension, diabetes, high lipids, high homocysteine, all well controlled. Also, may sure that heart is not a primary source for a secondary stroke. Tpa deals with acute ischemia. ...Read more
Poor blood flow: Inadequate blood flow to lower part of brain. It can improve with controlling BP & cholesterol, medications such as Aspirin and plavix, (clopidogrel) smoking cessation, heart healthy diet and exercise. Clot buster medication may be used within 90 minutes of an acute stroke and rarely angioplasty. ...Read more
Depends: Well unstable compared to whom. If you have recovered, we ordinarily would say you are stable but anytime a person has had ischemia, they are more likely to get a recurrence than a well person. And what is the ischemia secondary to would be an important question. Has the cause underlying the ischemia been corrected? ...Read more
Stroke: It means that the brain is not getting a normal blood supply. Depending on the cause and on the severity, that could lead to symptoms temporarily or to permanent damage and a stroke. ...Read more
I been diagnosed with cerebral ischemia. I have pain in my upper right arm that shoots to my head. Do I need to seek immediate medical attention?
Cerebral ischemia: Not likely related. But I would call Dr. Office in AM ...Read more
Do I need to look at how long the symptoms of neurological deficit lasted in cerebral ischemia to know whether this is a TIA or a ischemic stroke?
A typical transient ischemic attack lasts about 20-30 minutes in general, but some might be a bit longer.
Yet, if the symptoms persist over 24 hrs, almost certainly a stroke and may be visualized on an MRI. Generically, both should be treated in a preventative fashion to curtail recurrence. ...Read more
If I had temporary ischemia in a small part of the brain. If it affects memory wud my brain have to relearn how to store memory?
I have a history of traumatic brain injury and am experiencing dizziness when laying down. Is this a transient ischemic attack? Could this be a tia?
Unlikely: If it only happens with laying down, it is less likely to be a tia. That being said, if the dizzines feels like spinning and is associated with weakness, numbness, difficulty speaking or seeing, you should talk to your doctor, this could be a tia. ...Read more
I have chronic small vessel ischemia of bilateral cerebral white matter. How bad is it. Narrative?
Non-specific: Assuming this is on an MRI, it’s a relatively non-specific finding which can be found in diagnoses as varied as hypertension, diabetes, Lyme disease, MS and migraine headaches. Really depends on your age, medical history and symptomatology. This finding really can’t be properly interpreted in isolation. ...Read more
Had a brain MRI and it states the findings are associated with mild traumatic brain injury (i was I an accident in dec 2011) states also the white matter found which is bilateral is no evidence for acute ischemia or cerebral parenchymal bleed. This was g
The good news is that there was no bleeding found in your brain or areas that are damaged due to lack of oxygen. Mild traumatic brain injury is a fancy way to say concussion. A concussion is defined as the result of the forceful motion of the head or impact causing a brief change in mental status or loss of consciousness for less than 30 minutes.
Common symptoms include:
an important thing to note, is that these symptoms may not be present or noticed at the time of injury. It could take days or even weeks before any symptoms appear, and usually go unnoticed.
There is nothing to worry about, you will be just fine.
Take care. ...Read more
Any way to reduce/eliminate cerebral small vessel ischemia/calcification reported on Er CT after running accident.
Ischemia: Acute ischemia is potentially reversible, but I suspect that what they found on your CT scan are chronic changes due to small vessel vascular disease. These changes represent damage already done and cannot be reversed. However, this is a relatively common age related finding, and depending on the severity may not result in any significant impairment. ...Read more

Post-traumatic: Repetitive head trauma results in tissue changes quite similar to alzheimers but the lesions are closer to the brain surface. This was first noted in "punch drunk syndrome" in boxing. There is likely some affect on blood flow (ischemia), as one could conceive of a local type of bruising, but this not fully clarified. Regardless the nfl and nhl are both paying a lot of attention these days. ...Read more
I have just been diagnsed with brain stem ischemia after a fall 5 years ago. It is chronic and stable. I continue to have symptoms. Is there any tx?
Could midodrine cause too much vasoconstriction in the brain and cause reduced blood flow and even brain ischemia?
Midodrine: This is a very rare reported side effect, which is not proven to be definitely related to midodrine. ...Read more
Mri of my spine showing an intramedullary t2 hyperintense lesion at t1 (4mm) with dilatation of central canal. Ct brain -periventricular wm ischemia im only 49 with severe pain and mobility problems?
SEE NEUROLOGIST: There are several possible causes, and these include arteritis/vasculitis, multiple sclerosis, lyme disease, sjogren's, etc. Spinal fluid analysis may be necessary. Get diagnosed asap, and start treatment without delay. Changing your diet will not help this, you need medical care. We have loads of therapies to reverse and/or control all of this. ...Read more
