New research at the Ohio State University reveals details about sub-cellular change in the brain in a post-concussive state that might one day be used to provide better treatment to concussion sufferers and other patients with brain damage.
Researchers examined the changes in rodent brains when affected by laboratory induced mild traumatic brain injury. They found rapid microscopic swelling along the axons. The axons are the long, slender part of the nerve cell that sends vital messages to other parts of the brain. This same kind of swelling is also seen in Alzheimer’s and Parkinson’s patients.
There is some guarded good news, though—the swollen axons are reversible. It remains, however, unclear how exactly all this plays out in a human brain and the degree to which people may respond differently to brain trauma and other neurological problems.
