What this trial studies

This double-blind, randomized placebo-controlled trial aims to investigate the impact of omega-3 fatty acids, specifically DHA and EPA, on brain health in adult soccer players aged 18-30 who experience subconcussive head impacts. Participants will receive either omega-3 supplementation or a placebo while undergoing assessments including questionnaires, blood draws, brain imaging, and heart function tests. The study also includes a sub-cohort of participants diagnosed with ADHD for exploratory analyses. The goal is to determine how omega-3 supplementation may enhance neural resilience against repetitive head impacts.

Who should consider this trial

Good fit: Ideal candidates are adult soccer players aged 18-30 with at least 5 years of heading experience.

Not a fit: Patients with recent head or neck injuries, certain cardiovascular diseases, or those consuming omega-3 supplements or oily fish may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into how omega-3 fatty acids can protect brain health in athletes exposed to repetitive head impacts.

How similar studies have performed: While there is ongoing research into the effects of omega-3 fatty acids on brain health, this specific approach focusing on subconcussive impacts in soccer players is relatively novel.
