Primary Outcome Measures:
  • Change in levels of TBI biomarkers from baseline [ Time Frame: 36 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Association of TBI biomarker levels and the Post-Concussion Scale [ Time Frame: 36 months ] [ Designated as safety issue: No ]
  • Association of TBI biomarker levels and the Standardized Assessment of Concussion [ Time Frame: Baseline (beginning of Sports season), Active Phase (during Sports Season) and End of Sports Season ] [ Designated as safety issue: No ]
  • Association of TBI biomarker levels and the Balance Error Scoring System [ Time Frame: 36 months ] [ Designated as safety issue: No ]
  • Safety [ Time Frame: Throughout Participation in Study ] [ Designated as safety issue: Yes ]
    The safety endpoints include the cumulative procedure-related adverse event-free survival, and cumulative unanticipated procedure-related adverse events. The only potential risks to patients in this study are those that are normally related to routine blood collection.

  • Assessment of pituitary status and determination of the presence of autoantibodies. [ Time Frame: 36 months ] [ Designated as safety issue: No ]

Detailed Description:
Concussion or mild traumatic brain injury (mTBI) is a condition that affects hundreds of thousands of patients worldwide. It is a biomechanically induced neurological injury, resulting in an alteration of mental status, such as confusion or amnesia, which may or may not involve a loss of consciousness. Concussion affects about 1.6 million to 3.8 million athletes yearly, most commonly in contact sports such as American football and boxing. Early clinical effects of concussion include but are not limited to behavioral changes, impairments of memory and attention, headache, unsteadiness, and rarely, catastrophic severe brain injury (sometimes described as second impact syndrome). More recently, the consequences of repetitive mTBI from multiple concussions in a sports setting are becoming evident. Repeated concussions have been associated with greater severity of symptoms, with longer recovery time, and chronically with earlier onset of age-related memory disturbances and dementia. As a result and in contradistinction to the decades-earlier perception that these injuries were benign, sports medicine professionals are now increasingly being instructed to recognize and manage concussions as soon as they occur. "Understanding the neurobiology of concussion will lead to development and validation of physiological biomarkers of this common injury." These biomarkers (e.g., laboratory tests, imaging, electrophysiology) will then allow for improved detection, better functional assessment and evidence-based return to play recommendations.

Ages Eligible for Study:   18 Years and older

Study Population
The study will enroll athletes at the University of Florida, Gainesville. Teams considered for inclusion in the study are men's football, women's lacrosse and women's soccer.

Inclusion Criteria:

  • The subject is a University of Florida student athlete on a team participating in the study
  • The Subject is at least 18 years of age at screening (has had their 18th birthday)
  • The Subject is willing to undergo the Informed Consent process prior to enrollment into this study.
  • It is the Principal Investigator's opinion that based on the knowledge of the Subject that the Subject is an appropriate candidate for the study.

Exclusion Criteria:

  • Participating in another clinical study that may affect the results of either study.
  • Venipuncture not feasible (i.e. skin integrity compromised at the venipuncture sites, blood vessel calcification.
  • Not available for the end of season follow-up visit.
  • The Subject is otherwise determined by the Investigator to be medically unsuitable for participation in this study.
