How do changes in cognitive function underlie post-traumatic disorders?

The changes in cognitive function people experience following head injuries can act as underlying causes for post-traumatic disorders.

This is the finding of a study at Virginia Commonwealth University School of Medicine, which has advanced traumatic brain injury research.
For the first time, the study used sophisticated bioimaging and electrophysiological approaches to show that mild brain injury can cause structural damage to axon and change the way neurons work.

This leads to post-traumatic disorders and long-lasting neurological issues, researchers claim.

John T Povlishock, co-investigator on the study, commented: "These findings should help move the field forward by providing a unique bioimaging and electrophysiological approach to assess the evolving changes evoked by mild traumatic brain injury and their potential therapeutic modulation."

The study may lead to procedures that enable doctors to stop the lasting damage caused by head injury.

This follows the release of a recent paper that claims that an oestrogen hormone could help protect against traumatic brain injury.
