CONTEXT: Clinicians sometimes treat concussed individuals who have amnesia, loss
of consciousness (LOC), a concussion history, or certain symptom types more
conservatively, but it is unclear whether recovery patterns differ in individuals
with these characteristics. OBJECTIVE: To determine whether (1) amnesia, LOC, and
concussion history influence the acute recovery of symptoms, cognition, and
balance; and (2) cognition and balance are influenced by acute symptom type.
DESIGN: Cohort study. SETTING: Seven sports at 26 colleges and 210 high schools.
PATIENTS OR OTHER PARTICIPANTS: A total of 8905 collegiate (n = 1392) and high
school (n = 7513) athletes. MAIN OUTCOME MEASURE(S): The Graded Symptom
Checklist, Standardized Assessment of Concussion, and Balance Error Scoring
System were administered to all athletes during the preseason. To allow us to
track recovery patterns, athletes diagnosed with a concussion (n = 375) repeated
these assessments immediately after the injury, 3 hours postinjury, 1 day
postinjury, and at 2, 3, 5, 7, and 90 days after injury. RESULTS: Athletes who
experienced amnesia had markedly greater deficits in and a slower recovery
trajectory on measures of symptoms, cognition, and balance. Athletes with 2 or
more prior concussions demonstrated poorer balance than those with no previous
history. Otherwise, LOC and concussion history largely did not affect symptoms,
cognition, or balance. Greater deficits in balance scores were observed in
athletes with all symptom types. Regardless of these characteristics, most
athletes recovered within 7 to 10 days. CONCLUSIONS: Athletes who experienced
amnesia had more symptoms and greater deficits in cognition and balance. Symptoms
and cognitive or balance deficits were not consistently associated with LOC or
concussion history. Acute symptoms had a strong influence on balance scores and,
to a lesser extent, on cognition. However, we found no evidence to support more
cautious return-to-play decisions for athletes with these characteristics, as
group recovery occurred within normal timelines. Our study supports current
clinical practice: recommending that athletes be withheld from activity until
they are asymptomatic, followed by a graduated return-to-play progression.
