Respiratory syncytial virus is an extremely common cause of childhood respiratory infections resulting in significant morbidity and mortality. Although apnea is a well-known complication in young infants with respiratory syncytial virus bronchiolitis, the encephalopathy associated with this infection is not well recognized. ⋯ Based on our study of a cohort of children with respiratory syncytial virus bronchiolitis, we believe that neurologic complications, although relatively uncommon, represent a significant component of this common childhood illness. Furthermore, respiratory syncytial virus has been shown to release several mediators that could directly or indirectly be neurotoxic and induce an encephalopathy associated with the respiratory illness.

Football injuries account for more concussions than any other sport in North America. A 1977 survey of high school football players in Minnesota found that 19% of players reported at least one concussion (characterized by loss of awareness) during a season. These results have not been confirmed in subsequent studies. ⋯ The incidence of high school football players sustaining a concussion is much higher than previously established. The majority of these are mild (grade I) concussions. Further research is needed since multiple low-grade concussions may incur cumulative neuropsychologic impairments.
