What Is Atrophy Of The Brain
Cellular reaction: The white cells in our body react to toxic agents in a process that results in inflammation. Toxic material in bacteria, viruses, foreign tissue, etc can set off this inflammation. In the brain this can occur focally in an abscess, in brain cells as encephalitis, in the lining of the brain as meningitis, or any combination of these. Spinal fluid or brain biopsy best documents this inflammation. ...Read more
Atrophy usually refers to the skin-as you get older or if you have had alot of sun in the past-the dermis (that is the layer below the top layer which is called the epidermis) gets thinner and the skin looks more wrinked. Muscles and fat can also get thinner -this is another form of atrophy. Even the top layer gets thinner ...Read more
Most are random: All tumors result from accumulated genetic mutations that give a growth advantage to clones of cells. Most strike at random without clear environmental risks. A few familial syndrome (turcot's, neurofibromatosis, von hippel-lindau, lifraumeni, some rarities) feature increased risk for one or more types of brain tumors. If you have a brain tumor, nothing that you did caused it. Wishing you the best. ...Read more
Dumb luck: A few genetic syndromes put people at increased risk for brain tumors. Beyond this, we almost never find a cause. Tumors result from random mutations that become propagated. No one's to blame. Scientists who build careers by demonstrating new truths have failed to identify anything credible. The cell-phones claim has no rational or empirical basis. Best wishes. ...Read more
OPTIC ATROPHY: Dominant optic atrophy: most patients have no associated neurologic abnormalities, although nystagmus and hearing loss have been reported. The only symptom is slowly progressive bilateral vision loss, usually mild until late in life there are multiple types and etiologies of optic nerve atrophy. ...Read moreSee 2 more doctor answers
Dysphasia: Dysphasia refers to the neurological symptom, usually after a stroke in which the left hemisphere (the speech center) has been damaged and results in a difficulty either understanding or speaking language. There are various types: in some, the patient may not be able to make sense of what he hears, but can talk; in others, the patient understands, but can't find the words to say what s/he means. ...Read more
Injury to the brain: Concussion must be defined by the immediate reaction to brain injury. Most common is injury in sports. Alteration is awareness, disorientation, confusion, or even loss of consciousness is necessary to define concussion. Frequently there is also incoordination, clumsiness, visual distortion, inability to walk, poor balance, etc. A thorough evaluation must be done and recovery plan made. ...Read more
That depends: Basically to better evaluate the brain and orbits than you would see with a ct scan. Subtle findings are better seen with an mri- and it is frequently ordered after a negative ct scan. The combo 'brain and orbits' MRI is often ordered by physicians looking for signs of multiple sclerosis ( i would ask your doctor why they ordered it ). ...Read more
Many causes: Try Alzheimer's.org - they have nice details. Abnormal levels of a bad protein called AB42 in oligomer form along with hyperphosphoryated tau. TDP-43 and abnormal progranulin levels and others may also play a role in some cases. Inflammation is pivotal. Genetics defects can be in coding for an enzyme that forms AB42, or one that helps clear it from the brain. ...Read more
Depends: I'm not sure what you're asking. Some brain rumors are benign, cured by surgery, such as meningioma. Others are malignant but with a slow growth pattern, such as low grade astrocytoma. Others are rapidly growing, usually fatal, such as glioblastoma multiforme. Brain tumors can also be metastatic from other sites, such as a spread of lung or breast cancer. ...Read more
Grey: Brain cells have a neutral grey appearance in the living person. Interconnections between these cells can be grey or whitish due to an insulating layer termed myelin. But the cells from which these connections arise are neutral grey. ...Read more
