<p><b>Study Description: </b> Established in 2014, the U.S. Department of Defense (DoD) and the National Collegiate Athletic Association (NCAA) funded the Concussion Assessment, Research and Education (CARE) Consortium to inform science, clinical care and public policy related to concussion and repetitive head impact exposure (HIE) in U.S. Military Service Academy (MSA) cadets and collegiate student-athletes. The primary aims of the initial study were to: (1) establish a multisite research consortium to characterize the effects of concussion and repetitive head impact exposure on brain health, (2) characterize the clinical sequelae and natural history of concussion, (3) characterize the effect of concussion and repetitive head impacts on brain structure and brain function. The 30 member institutions of the CARE Consortium (26 civilian universities/colleges and 4 military service academies) agreed to invite all varsity athletes to undergo multimodal clinical assessments at preseason baseline, and at 5 additional timepoints after concussion diagnosis. At the service academies, non-varsity athlete cadets/midshipmen were also studied. <br></p><div><b><u><br></u></b></div><div><b><u>Assessment Categories At Each Time Point </u></b></div><br><div><b>Baseline: </b></div><div>• Demographics </div><div>• Personal and Family History </div><div>• Neurocognitive Assessment </div><div>• Neurological Status </div><div>• Postural Stability </div><div>• Symptoms </div><br><div><b>ACUTE POST-INJURY FOLLOW-UP (CARE 1.0) </b></div><br><div><b>(24 hrs; 48hrs; Asymptomatic; Unrestricted Return to Play (RTP); 6 mos) </b></div><div>• Neurocognitive Assessment </div><div>• Neurological Status </div><div>• Postural Stability </div><div>• Symptoms </div><br><div><b>CUMULATIVE &#x26; PERSISTENT EFFECTS.
