[The undetected brain lesion in sports. Minor traumatic brain injury and its sequelae].
The minor traumatic brain injury (mTBI) in sports is often looked at as a bagatelle. The treating physician underestimates the severity of the injury suspecting that a mTBI is a nonstructural lesion with an overall excellent prognosis in the majority of the cases. This paper shows that the minor traumatic brain injury may be a structural brain lesion with potentially life-threatening dangers. The therapy should follow exactly defined guidelines, e.g., stepwise protocol of the Concussion in Sports (CIS-) Group. Return to sports activities should happen only when all physical but also cognitive symptoms have subsided. All mTBIs that have been sustained prior to the actual injury have to be recorded properly because repeated mTBIs may cause chronic degenerative brain damage. Neuropsychological testing will aid in the correct diagnosis of a mTBI and is a useful parameter in the course of the injury. In the future biochemical markers may serve as indicators of the severity of the brain injury and may also aid in predicting the outcome after TBI. Today biochemical markers do not serve as a substitute for neuroimaging.
