Football season is upon us, and although concussions occur year round, this seems like an appropriate time to briefly discuss concussions. Athletes who suffer a concussion during the season are at increased risk of recurrence during the same year. Studies have demonstrated a decrease in cognitive function in association with repeated head trauma. There are also concerns regarding second impact syndrome, but because of the very small number of documented cases, the diagnosis is controversial.
Data is not readily available to guide decisions about the timing of return to sports after concussion. However, conservative recommendations reflect concern regarding second impact syndrome. Sideline evaluation generally includes tests of mental function and coordination and provocation of symptoms such as headache, dizziness or unsteadiness with exertion.
