Traumatic Brain Injuries Of Some Veterans

Traumatic Brain Injuries Of Some Veterans.


The brains of some veterans of Iraq and Afghanistan who were injured by homemade bombs show an extraordinary templet of damage, a small investigate finds. Researchers speculate that the damage - what they call a "honeycomb" pattern of broken and dropsical nerve fibers - might help explain the phenomenon of "shell shock". That word was coined during World War I, when trench warfare exposed troops to constant bombardment with exploding shells try vimax. Many soldiers developed an array of symptoms, from problems with envisaging and hearing, to headaches and tremors, to confusion, hunger and nightmares.



Now referred to as blast neurotrauma, the injuries have become an grave issue again, said Dr Vassilis Koliatsos, the senior researcher on the new study fungus. "Vets coming back from Iraq and Afghanistan have been exposed to a category of situations, including blasts from improvised uncertain devices IEDs ," said Koliatsos, a professor of pathology, neurology and psychiatry at Johns Hopkins University in Baltimore.



But even though the perception of shell shock goes back 100 years, researchers still discern little about what is actually going on in the brain. For the new study, published recently in the fortnightly Acta Neuropathologica Communications, his team studied autopsied brain tissue from five US disagreement veterans. The soldiers had all survived IED bomb blasts, but later died of other causes. The researchers compared the vets' wit tissue to autopsies of 24 relatives who had died of various causes, including traffic accidents and drug overdoses.



The soldiers' brains showed a separate pattern of damage to nerve fibers in key regions of the brain - including the frontal lobes, which wear the pants memory, reasoning and decision-making. He said the "honeycomb" model of small lesions was unlike the damage seen in people who died from head trauma in a car accident, or those who suffered "punch-drunk syndrome" - genius degeneration caused by repeated concussions.



Before their deaths the five vets did show signs of "neuropsychiatric" problems, such as despondency and anxiety. One died of a gunshot lesion to the head, and three died of methadone overdose. Those overdoses could have been accidental, since the pharmaceutical is prescribed for severe pain. It's not clear whether any of the soldiers' symptoms can be blamed on the brain cost seen in this study, according to Koliatsos.



But "you have to raise the question, 'Could the neuropsychiatric problems be related to this frontal lobe dysfunction?'" Another qualified said it "provides preliminary evidence to support structural and solid changes associated with blast brain injuries. I think this is an important next bow out in our understanding of how blast injuries can impact military personnel and veterans, even if we can't easily 'see' the injuries using customary medical techniques," said Craig Bryan, executive director of the National Center for Veterans Studies at the University of Utah, in Salt Lake City.



Both he and Koliatsos said further studies are needed to recognize these findings, and to get what this brain damage "signature" means. "My expect is that research such as this will eventually lead to better diagnostic tests that can detect and identify otherwise hidden injuries much sooner". It could also produce to more refined treatment, according to Koliatsos.



For example, if damage to the frontal lobes is causing some blast-injured veterans' symptoms, then curing might include medications that stimulate the frontal lobes. But that's for prospective studies to figure out. "It's premature to say what this means for veterans front now". The most important thing is for blast-exposed vets to seek treatment for any persistent symptoms phenibut. "If you're having problems, talk to your family and talk to your doctor".
