be caused either by a direct blow to the head, face, neck, or elsewhere on the body with an impulsive force transmitted to the head; result in the rapid onset of short-term impairment of neurological function that resolves spontaneously (but may evolve over hours); result in neuropathological changes, but the acute clinical signs and symptoms are largely a functional disturbance rather than a structural injury and cannot be imaged effectively; produce clinical signs and symptoms that may or may not involve loss of consciousness. So, concussive injuries don’t require head contact, produce deficits that arise quickly and are usually brief, can’t be seen using conventional imaging, and don’t need to involve getting "knocked out." But do people active in combat sports, where concussion risk is quite high, actually know any of this? Recently we published a study called ‘Understanding concussion knowledge and behaviour among mixed martial arts, boxing, kickboxing, and … [Read more...] about The Vicious Cycle of Concussion Ignorance in Combat Sports
