WEDNESDAY, Nov. 21 (HealthDay News) -- Researchers who identified brain changes in people with post-concussion syndrome say their findings may lead to improved detection and treatment of the disorder.
In this study, published online Nov. 21 in the journal Radiology, researchers conducted MRI brain scans of 18 healthy people and 23 people who had symptoms of post-concussion syndrome two months after suffering a mild-traumatic brain injury.
The MRI scans were done when the participants' brains were in a resting state, such as when the mind wanders or while daydreaming. It is believed that the resting state involves connections among a number of brain regions and that the default-mode network plays a major role, study author Dr. Yulin Ge, an associate professor in the radiology department at the NYU School of Medicine in New York City, said in a journal news release.
This study found that communications and information integration in the brains of the people with post-concussion syndrome were disrupted among key default-mode network structures, and that the brain had to tap into different areas to compensate for this impaired function.
Through their ongoing research, Ge and colleagues hope to identify a biological feature, or biomarker, that can be used to monitor post-concussion syndrome progression and recovery, and to assess the effects of treatment.
