Headaches show up in 95% of football concussions, and dizziness follows in 85% of diagnosed cases. Cognitive fog is reported in 71% of youth concussions, while neck pain appears in 60%. These symptom patterns help explain why concussions continue to disrupt players long after the impact.
Key Takeaways
- Immediate symptoms include headache in 95% of football concussions
- In the NFL from 2012-2014, there were 887 diagnosed concussions across regular season and postseason games, averaging about 0.41 concussions per game
- CTE found in 99% of deceased NFL players' brains (111/111 examined)
- Helmet rule changes reduced concussions by 34% in NFL 2010-2019
