“In the last 20 years, the public awareness of concussion and its long-term effects on the brain has increased and so has research into the topic. But there has been scant research using resting-state fMRI at the intersection of the adolescent/young adult population and athletes with multiple concussions,” says Thomas Johnson, M.D., Ph.D., a resident doctor in neurology on the University of Rochester Medical Center in Rochester, New York.
Brain Connectivity and Concussion
The research group enrolled 142 concussion sufferers (67 feminine, imply age 18.2 years) and age- and sex-matched controls (12 feminine, imply age 20.7) in a concussion clinic on the University of Rochester Medical Center for post-concussion syndrome.
Symptoms like dizziness, complications, fatigue, and irritability have been famous and sufferers have been analyzed utilizing resting-state fMRI.
It was discovered that sufferers who had three to 5 concussions, have been detected with a disruption within the default mode community as in comparison with controls. However, no variations have been discovered within the DMN connectivity amongst those that had skilled one or two concussions.
“Suffering three to five concussions has the potential for long-term disruption of cognitive processes. We need to determine our tolerance for concussions. When do we say no more contact sports? We need more evidence to set some limits for people,” says, Johnson.
The research findings could thus assist formulate thresholds at which concussions trigger results, which in flip could assist inform protocols for enjoying contact sports activities following a concussion.
