Second impact syndrome can result from even a very mild concussion that occurs days or weeks after the initial concussion. What is Second Impact Syndrome? In patients who sustain a second concussion when the first one has not fully healed, the brain loses its ability to auto regulate intracranial and cerebral perfusion pressure. This may lead to cerebral edema (severe swelling of the brain) and possible brain herniation. Loss of consciousness after the initial injury followed by secondary brain damage creates ionic fluxes, acute metabolic changes, and cerebral blood flow alterations. All of these characteristics enhance the vulnerability of the brain and greatly increase the risk of death, even if the second injury was far less intense. 1, record 1, English, - second%20impact%20syndrome

Sans conteste, le plus tragique dénouement qui puisse survenir dans la phase aiguë à la suite de commotions cérébrales répétées s’avère le syndrome du second impact (SSI). Le SSI surgit habituellement lorsqu’un athlète subit un coup à la tête avant la disparition des symptômes aigus d’une commotion cérébrale récente [...]. Dans les secondes ou minutes qui suivent le second impact, l’athlète s’écroule typiquement au sol dans un état semi-comateux. Les conséquences du SSI sont bien souvent catastrophiques, allant de séquelles permanentes au cerveau au décès de l’athlète. Des études s’intéressant aux mécanismes d’action du syndrome du second impact font état d’une encéphalopathie diffuse, principalement caractérisée par une enflure du cortex cérébral («diffuse cerebral swelling»), qui entraîne de sévères complications [...]. Bien qu’il s’agisse de phénomènes plutôt rares [...], leurs conséquences catastrophiques justifient à elles seules que les cliniciens œuvrant auprès de la clientèle sportive adoptent une attitude particulièrement conservatrice dans la gestion du retour au jeu des athlètes [...]. 1, record 1, French, - syndrome%20du%20second%20impact
