Legal Claims for Second Impact Syndrome
Second impact syndrome (SIS) occurs when a person sustains a second concussion before fully recovering from an initial concussion. This second impact — even one that appears minor — can trigger catastrophic, often fatal brain swelling. According to research published in the journal Neurology and the American Journal of Sports Medicine, second impact syndrome carries a mortality rate of approximately 50%, and nearly all survivors suffer permanent, severe brain damage. SIS most commonly affects young athletes who are returned to play before their initial concussion has fully healed.
At Roden Law, our second impact syndrome lawyers represent victims and families in Georgia and South Carolina who have suffered catastrophic brain damage because a coach, school, sports organization, or medical provider negligently allowed an athlete to return to activity while still recovering from a concussion.
How Second Impact Syndrome Occurs
After an initial concussion, the brain is in a vulnerable state. Normal regulatory mechanisms controlling cerebral blood flow and intracranial pressure are impaired. When a second concussive impact occurs during this recovery window, the brain loses its ability to regulate blood flow entirely. The result is rapid, massive cerebral edema (brain swelling) that increases intracranial pressure to dangerous levels within minutes. This chain of events can cause brainstem herniation, loss of consciousness, respiratory failure, and death — often within minutes of the second impact.
The critical lesson is that the second impact does not need to be severe. Even a relatively minor blow, jolt, or whiplash-type motion can trigger SIS in a brain that has not fully recovered from a prior concussion.
Georgia and South Carolina Concussion Return-to-Play Laws
Both states have enacted legislation specifically designed to prevent second impact syndrome:
Georgia’s Return to Play Act of 2013 (O.C.G.A. § 20-2-324.1) mandates that any youth athlete suspected of sustaining a concussion must be immediately removed from play and prohibited from returning until cleared in writing by a qualified healthcare provider. The law applies to all youth athletic activities organized by schools and youth sports organizations.
South Carolina’s Youth Athletic Concussion Prevention Act (S.C. Code § 59-63-75) imposes identical requirements — immediate removal and mandatory medical clearance before return. Coaches and organizations that violate these laws bear direct liability for resulting brain injuries.
Violation of these statutes constitutes negligence per se — automatic proof of negligence — in a lawsuit for second impact syndrome injuries.
Who Is Liable for Second Impact Syndrome
Multiple parties may bear responsibility for SIS injuries:
- Coaches: Who pressure athletes to return, ignore symptoms, or fail to recognize concussion signs
- Schools and school districts: That fail to implement or enforce concussion protocols
- Youth sports organizations: That lack trained personnel or adequate concussion policies
- Athletic trainers: Who improperly clear athletes for return to play
- Medical providers: Who provide premature return-to-play clearance without adequate evaluation
- Sports facility operators: Who fail to enforce safety protocols for sports-related injuries
Proving Second Impact Syndrome Claims
SIS claims require establishing that the first concussion occurred and was known or should have been recognized, the victim was returned to activity before full recovery, a second impact occurred during the vulnerable recovery period, and the devastating brain injury resulted from the premature return to activity. Evidence includes medical records documenting the initial concussion, witness testimony regarding the athlete’s symptoms, communications between coaches, parents, and medical staff, and expert medical testimony on the pathophysiology of SIS.
Damages in Second Impact Syndrome Cases
Because SIS causes catastrophic or fatal brain injuries, damages are typically among the highest in personal injury law. Recoverable damages include lifetime medical and rehabilitation costs, 24/7 attendant care for survivors, complete loss of earning capacity, pain and suffering, loss of enjoyment of life, and wrongful death damages when SIS is fatal. Punitive damages may be available when coaches or organizations consciously disregarded concussion protocols and known risks.
