@entity542 is frequently followed by a subjective postconcussion syndrome. Brain-stem auditory evoked responses (BAER's) were found to be pathological in different small series of @entity1 with a postconcussion syndrome who were examined months after sustaining a slight cranial or cervical @entity130 ; abnormal BAER's have also been reported in larger groups of @entity1 examined early after @entity542 . A relationship between these findings and late subjective symptoms has never been demonstrated. The results of a prospective study into the value of BAER's in the prognosis of a postconcussion syndrome after @entity542 are presented. In 103 @entity1 with @entity542 , BAER's were recorded within 48 hours of the @entity130 . One year later, the @entity1 were examined for @entity10 , @entity1296 , @entity308 , @entity148 , subjective @entity2414 and concentration, and @entity146 . Eighty percent claimed at least one symptom, most often @entity146 (54%), @entity2414 (47%), or @entity308 (39%). Pathological BAER's were found with the same prevalence in @entity1 with and without a postconcussion syndrome. This study confirms the disturbance of brain-stem function in some head-injured @entity1 . However, the lack of correlation with a postconcussion syndrome limits the prognostic value of BAER recordings for postconcussion syndrome. The data suggest that BAER's not be used for medicolegal evaluation of @entity1 with a postconcussion syndrome.
