What this research studies

You would join a research program that monitors hormone and brain changes after a concussion during adolescence. Researchers will collect saliva or blood samples to measure cortisol and other pubertal hormones, perform brain imaging, and have you complete mood and symptom questionnaires over time. The team will compare teens with recent concussions to teens without injury to see how the stress axis and pituitary function differ. The goal is to understand why some teens develop anxiety or emotional problems after concussion while others recover.

Who could benefit from this research

Good fit: Ideal candidates are adolescents in puberty who recently had a concussion and are willing to provide hormone samples, attend brain scans, and complete follow-up visits.

Not a fit: Adults, people with severe traumatic brain injury, or those with unrelated hormonal disorders may not be eligible or likely to benefit from this work.

Why it matters

Potential benefit: If successful, this could help identify hormonal signs that predict which teens are at risk for long-lasting mood or emotional problems after concussion.

How similar studies have performed: Early iCARE2 findings and some clinical reports point to pituitary and hormone changes after concussion, but the specific role of cortisol in post-concussion symptoms remains unclear.
