Is brain damage always permanent?
The brain is living and evolving as the rest of the human body. Furthermore, the common belief used to be that neurons were the only cells in the body that cannot replicate themselves, i.e., you had a fixed amount allocated, and when they died that was it, and what made the difference was the richness of connections between those different neurons. However, although that richness of connections is for sure important, more recent research has found evidence that neurons can also replenish, so never say never. Add to that the fact that, although we know the areas where each brain function is more or less located, each individual works in a different way and that's true for their brain architecture too. Like a plant finds its way through rocks to keep on growing, a damaged brain is an alive entity that, as long as it's alive, looks for new ways to evolve and keep on growing. The danger with comparing the brain to a computer is that we sometimes forget that, unlike the computer, the brain is an alive thing, made of alive cells. And cells can evolve and change in response to the circumstances, there's nothing fixed.
I have been having symptoms of brain damage but every time my doctor tests me, he says nothing is wrong but he won't let me see the tests. I have dizziness, headaches, seizures, and have trouble breathing at times. What should I do?
I guess it’s about brain scans, and I doubt you could interpret the images. It starts with that. If you have brain damage, it shows in a multitude of ways, few to none of which are obvious even to trained physicians in other disciplines.If your symptoms persist and the physician claims that it’s not physiological, seek a second opinion. All your symptoms can have a multitude of reasons, from nutrition to lack of sleep, psychogenic causes, viruses, bacteria, fungi, environmental, and more. They don’t have to show on a MRT or CT, and very few actually do.Instead, find a physician who exhausts all other avenues with you as well, from diaries to frequent lab tests, before attempting to diagnose yourself over brain scans.As for your lab results, there should not be a reason he’s withholding them, so ask for them to be given to you before visiting your new physician. But, please, don’t try to diagnose yourself. Google is a bad physician.
Can MRI detect skull fractures?
Apologies, yet in perspective of additionally perusing the supplemental history you gave, I trust your posted inquiry is altogether disputable! What do your Neurologist and Neurosurgeon need to say in regards to deciding if you have a skull break beside the one you apparently self-incurred?On the off chance that they don't trust it would have any effect in treatment, WHO CARES whether MRI can identify skull cracks? I bet that you aren't seeing the backwoods for the trees and that only you are concentrating on insignificant minutia. Indeed, I concede that I could not be right about your thought process. medical imaging parts I'm thinking about whether you defined this inquiry in light of the fact that your subsequent intracranial imaging is being finished with MRI just and not with any CT. On the off chance that that is the situation, bring up that issue with your overseeing Physician(s).Presently, to answer your inquiry truly, truly, MRI can identify skull cracks. Be that as it may, it unquestionably is NOT a first-line imaging methodology for this sign! X-ray's affectability for identification of skull cracks is enhanced IF one limits the kind of break to those that include a component of gloom. X-ray does not exhibit cortical bone so well as X-radiography can (en confront) or a thin cut [profile] winding CT sweep can. Note that such a CT system is NOT routinely utilized, i.e. not for CT sweeps of the mind, essentially.
Can we see the brain AVM on a non-contrast MRI or CT scan?
Nota Bene: Given the manner in which this question is posed, I suspect that the OP is asking whether the finding of an AVM would be made incidentally by one of these imaging techniques. Thus, each of my responses is couched in terms of a relative probability!On an unenhanced CT scan of the brain employing a routine protocol, doubtful unless the AVM is large.On a routine (protocol) unenhanced MRI of the brain, doubtful unless the AVM is medium-or-so in size.On an unenhanced MRA of the brain using only a 3D TOF GRE pulse sequence, there's a decent chance it would be detected.
CT Scan Radiation Damage...Now What?
Our infant received a CT scan 24 months ago. The diagnosis was "minor" head injury. She did not vomit after the fall. She did not become unconscious after the fall. She was functioning fine after the short fall down 4 wooden steps. After visiting the physician from a center open on Sundays (her Pediatrician's office is closed on Sundays), my instincts told me to avoid the scan and watch her for abnormal behavior. We were not given the option of an MRI, ultra-sound, standard x-ray, observation, or any less invasive procedure. We were not explained the extent of risk involved in CT brain scans to an infant's head by the physician. It was not until after her scan that we were able to research, to our HORROR, the lifetime risks of CT brain scans to an infants head and when it is and when it is not necessary to prescribe such scans. It is UNTRUE that one dose of ionizing radiation from a CT scan on an infant is relatively safe. It is now estimated, from a recent study completed at UCSF (see link below) that 1 in 60 female children, aged 18 months or younger receiving a single CT scan will die as a direct result from the CT scan. Now what do we do? Aside from attempting to avoid future ionizing radiation what can we do to help remove free radicals and DNA damage from this? http://www.ucsf.edu/science-cafe/articles/new-research-on-ct-radiation-exposures-risks-fuels-growing-concern/ http://energycommerce.house.gov/Press_111/20100226/Smith-Bindman.Testimony.pdf http://www1.voanews.com/english/news/health/CT-Scan-Radiation-Draws-more-Concern-83150382.html http://www.psa-rising.com/eatingwell/veggies-dna2006.htmlhttp://www.calharvest.com/nutr.dna.html
What does this Brain MRI report mean?
My son is seven, has fine motor and speech delays, possible ADHD, Autism, and has precocious puberty with a bone age of 11 1/2 and he's 4'10 1/2" and 120 lbs. Here is his report can someone please explain???? Protocol: T1 weighted sagittal, axial and coronal images as well as FLAIR, gradient echo and turbo T2 weighted axial images were obtained. There are no comparison studies. Study interpreted at University hospitals case Medical Center. Findings: There is no evidence of abnormal diffusion restriction . The lateral ventricles are minimally generous in size but there is no evidence of hydrocephalus. Rather, this may reflect a very subtle paucity of supratentorial white matter. The corpus callosum is unremarkable in appearance, however, without evidence of thinning. The myelination pattern is complete. No parenchymal signal abnormalities are appreciated. There is no evidence of intracranial mass, hemorrhage or edema. No definite structural abnormalities are visualized. The pituitary axis is grossly intact. Visualized paranasal sinuses and mastoid air cells are clear. Impression: Mild lateral ventriculomegaly, probably reflecting slight paucity of supratentorial white matter of uncertain etiology. Otherwise unremarkable exam.
For how long is a brain MRI valid?
If you look closely at your brain MRI, somewhere on your brain there will be stamped an expiration date. At least, that is what I have heard. I have not yet seen it myself!To be serious, it all depends on the type of pathology, if any. Some diseases advance quickly, some diseases advance slowly, some diseases stabilize, and some diseases spontaneously resolve.If your brain MRI is normal, there is no reason to get another one unless some symptoms or signs appear.
