Is this trial a fit for you?

Likely a good fit

Ideal candidates include retired professional football players aged 29-59 who have played at least three seasons and matched male controls with a high school education or higher.

Probably not a fit

Patients who have played organized football beyond high school or have a history of severe traumatic brain injury may not benefit from this study.

What this trial studies

This project aims to evaluate the prevalence of brain health among retired professional football players compared to matched controls. It involves comprehensive assessments including cognitive and neuropsychological testing, vestibular and ocular-motor evaluations, sleep assessments, and MRI scans. The study focuses on understanding the impact of traumatic brain injury on cognitive, neuromotor, and behavioral functions in these individuals. By gathering clinical, neuroimaging, and biomarker data, the study seeks to provide insights into the long-term effects of playing professional football.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of brain health issues in former professional athletes.

How similar studies have gone: Other studies have shown success in assessing brain health in athletes, but this specific approach focusing on retired football players is relatively novel.
