CTE, Repeat Concussions, and Youth Athletes: What Parents Should Actually Worry About

Written by Dr. Rob Letizia, PT, DPT.

Every parent of a contact-sport athlete has heard of CTE - chronic traumatic encephalopathy, the degenerative brain disease first widely publicized through studies of retired NFL players. Between the Will Smith movie Concussion, ongoing litigation, and constant media coverage, CTE has become the monster under the bed for parents of football, hockey, soccer, and lacrosse players.

CTE is real and serious. But the actual risk profile for youth athletes is more nuanced than the headlines suggest, and the evidence-based steps parents should take are specific and practical. Here is what you should actually worry about and what you should do about it.

What CTE Actually Is

Chronic traumatic encephalopathy is a progressive neurodegenerative disease associated with repeated head impacts over many years. It is characterized by tau protein deposits in brain tissue, and its symptoms - memory problems, mood changes, impulse control issues, eventually dementia - typically appear years or decades after the athletic career ends.

Currently CTE can only be definitively diagnosed post-mortem through brain tissue analysis. Research is actively working on in-vivo biomarkers, but none are clinically available yet.

The Data on CTE Risk

Here is what current research suggests:

• CTE risk appears to correlate with cumulative sub-concussive impacts, not just diagnosed concussions. Repetitive small impacts may matter more than individual severe ones.
• Risk appears to be highest in athletes with long careers in high-impact positions (football linemen, hockey enforcers, soccer players who head the ball frequently over many years).
• Youth participation alone in contact sports has not been clearly shown to cause CTE. Most studies are in former professional or long-career collegiate athletes.
• However, earlier age of first exposure may correlate with earlier symptom onset if CTE does develop.
• Genetic factors likely play a role - some athletes sustain extensive impacts and do not develop CTE, while others with less exposure do.

What the Risk Looks Like for a Youth Athlete

For a high school athlete playing varsity football, soccer, lacrosse, or hockey for 4 years, CTE risk is:

• Probably low in absolute terms if they do not continue into high-impact college or professional play
• Not zero, particularly if they sustain multiple diagnosed concussions
• Harder to quantify than most parents would like, because the research is still maturing

The bigger acute risk for most youth athletes is actually poorly managed post-concussion syndrome that costs them months of their season, grades, mental health, and sometimes athletic career - problems that are 100% preventable with proper rehabilitation.

What Parents Should Actually Do

1. Take every concussion seriously

The single strongest controllable risk factor is proper management of each individual concussion. Rushing back to play after a concussion that is not fully resolved raises the risk of a subsequent concussion - and cumulative concussion history is the biggest modifiable CTE risk factor.

2. Get the full 4-domain rehabilitation

Athletes who complete structured post-concussion rehabilitation (vestibular, cervical, autonomic, ocular-motor) return with genuinely resolved symptoms rather than "good enough to play." This protects them from the second-impact vulnerability window.

3. Know your sport's sub-concussive impact profile

In football, linemen sustain far more sub-concussive head contact than skill-position players. In soccer, heading the ball is a significant cumulative impact source. In hockey, enforcers and centers see more contact than wingers. Talk with your coach about position-specific exposure.

4. Strengthen the neck

Research consistently shows that greater neck strength reduces the impact energy transmitted to the brain in any given head contact. Neck strengthening programs are evidence-based and underutilized.

5. Require medical clearance - and a second opinion for concerning cases

Never let your athlete return to contact after a concussion without full medical clearance. For multi-concussion athletes, get a second opinion from a sports medicine physician or neurologist familiar with concussion history.

6. Reconsider position or sport after multiple concussions

Two concussions in a season or three concussions in a career should trigger a serious conversation about whether to continue in the same sport, consider a position change, or step away. This is a family decision - but it should be informed by a sports medicine evaluation.

The Bottom Line

CTE risk for most youth athletes is not zero, but it is also not the certainty some coverage suggests. The practical steps that matter - proper concussion management, 4-domain rehabilitation, neck strengthening, position and sport re-evaluation after multiple concussions - are all within your control. Panic is not productive. Informed decisions are.
