Does Small Vessel Damage In Brain Cause Pain In Brain
AVM: A 2mm avm is an extremely small size avm and impressed they were able to find it on radiologic studies. An avm always has a risk of bleeding but if only 2mm in size this would be a low flow avm and the risks on the lower size. I would recommend followup in the future to make sure there is no growth in the avm as that would change the treatment. ...Read more
Totally confused: i'm not sure what you mean. All arteries, not just brain arteries, have fluid in them. The fluid is called blood. When an artery does NOT have fluid in it is when you worry. ...Read more
Can ischemic small vessel disease cause gliosis? How would ischemic small vessel disease be treated in a minimal area of white matter in the brain?
Raynauds: By definition arterial spasms induced by cold. Can occur independently of other conditions or as part of other diseases. Thermaly speaking temperature in brain fairly constant. That are other conditions including vascular headaches which occur based on vasospasm with frequently other causes such as diet and smoking. ...Read more
Can a brain tumor cause problems in other parts of the body? (ex: stomach ulcers, sickness) if a brain tumor is present near the optical part of the brain, can it cause problems in the body such as sickness?
Cancer-no, Stroke-?: AVM's (artero-venous malformations) do not cause cancer. Whether or not they may cause a stroke, depends! The location, size, luck, and other risk factors all must be figured in. Lots of people have AVM's in their brains and elsewhere and never know they have them because they never cause problems. ...Read moreSee 1 more doctor answer
Can a lumbar puncture that caused explosive pain in the thigh cause nerve damage and muscle weakness in the same area? Is that damage permanent?
Could : Whether there is damage (let alone whether it is permanent) can be best determined by a good neurologic exam and may require an emg. ...Read more
Does injury or abnormality in CNS or cranial nerves cause EKG changes or disturbance in electrical signals? Does nerve damages above c-1 cause breathing difficulties? How can they identify which nerves are damaged? From the symptoms?
The : The major nerve controlling heart rate, vascular tension, and gastrointestinal function is the vagus nerve. It is the 10th cranial nerve. It can be compressed or injured a few places between the brainstem and the chest. So, there is at least one way an injury to the neck or brainstem can relate to heart rate, ekg, and breathing. An injury "above c1" implies a brain injury. If it is located in the brainstem, it would have to be very small to be survivable. This area controls many functions that are "primitive"--that is to say, common to all animals. That would include heart rate and breathing. When we talk about brainstem injury, we talk about cranial nerve signs and "long tract" signs, meaning the extremities. By finding the intersection of the involved nerves, the area can be identified. Injuries above the brainstem can be a bit more difficult to localize. Cerebellar problems can be difficult to diagnose and often involve balance and coordination. The midbrain is a relay area of sensory and motor signals. The cerebral cortices, on the other hand, are reasonably well-mapped and those lesions can be recognized more easily. A neurologist or neurosurgeon can help diagnose and treat the problem. Often MRI is needed to help locate and diagnose the problem. To be useful, though, the images should correspond to the symptoms and exam findings. ...Read more
Could midodrine cause too much vasoconstriction in the brain and cause reduced blood flow and even brain ischemia?
Confusing question: I would suppose that an eye nerve can self destruct in a number of ways, and if so it's function would end. It would wither and be replaced by scar tissue. Nerves do not have the tendency to "rupture" like you might understand a blood vessel would do with a weak wall. Blood vessel ruptures cause injury to nearby tissue. When nerves die, they just quit working. ...Read more
Does a sroke in the left anterior cerebral territory and deep white matter cause central post stroke pain syndrome?
Central pain: Central pain from stroke typically follows thalamic strokes. This part of the brain not in the anterior cerebral territory however this does serve the orbital frontal cortex that could in theory cause some changes in how your brain processes pain. Stroke in young adults requires an extensive workup including a hypercoagulable evaluation. Best health. ...Read more
The same as for...: ...ANY tissue or organ. Could be vascular, infectious, inflammatory, metabolic, traumatic, nutritional deficiency, endocrine, neoplastic, drug-induced, genetic, mechanical, degenerative...I think that about covers it. That's probably not the sort of answer you wanted, but your question is like asking what causes unhappiness: It's too unfocused to be answered in any other way. ...Read more
Yes. Call Now!: Patients who have had carotid artery surgery definitely have a risk of stroke. The highest risk of stroke is during and immediately after the procedure and is generally quoted at about 2%. If you are experiencing any signs of stroke and have had recent carotid surgery call your surgeon immediately or go to the emergency room. Difficulty speaking or weakness on one side of the body would be the most common complaints. ...Read moreSee 2 more doctor answers
Is a small hyperintensity of 3mm in the cerebellum significant or can this occur in healthy individuals on a brain mri?
No and yes: We are mostly water. MRI picks up differences in the local chemistry of water. Anything "abnormal" looks bright (hyperintense). MRI's sensitivity is higher than its specificity, meaning that it's good at picking up certain things but not as good at distinguishing between "normal" and truly "abnormal." One little bright spot in an otherwise normal brain is almost never clinically significant. ...Read more
