How should a 17-year-old with a concussion be evaluated and managed?

Management of a 17-Year-Old with Concussion

A 17-year-old with concussion should be immediately removed from play, never returned to activity the same day, and managed with complete physical and cognitive rest for the first 24-48 hours, followed by a graded return-to-activity protocol that takes a minimum of 5 days once asymptomatic. 1

Immediate Evaluation and Diagnosis

The diagnosis is clinical, based on symptom reporting and functional assessment. Key evaluation components include:

• Symptom assessment: Headache, dizziness, nausea, balance problems, sensitivity to light/noise, feeling "foggy," difficulty concentrating, memory problems, emotional changes 1
• Cognitive testing: Use standardized tools like the Standardized Assessment of Concussion (SAC) for immediate memory, concentration, and orientation 1
• Balance examination: Balance Error Scoring System to detect postural instability 1
• Visio-vestibular screening: Critical for identifying dysfunction associated with prolonged recovery 2, 3

Important caveat: Loss of consciousness occurs in less than 10% of concussions and is NOT required for diagnosis. If LOC exceeds 30 seconds, consider more serious intracranial injury 1. Neuroimaging (CT/MRI) is typically normal in concussion and should only be obtained if you suspect structural injury—prolonged altered consciousness, focal neurological deficits, or worsening symptoms 1.

Acute Management (First 24-48 Hours)

Complete rest is mandatory initially 4, 2:

• Physical rest: No sports, exercise, or strenuous activity
• Cognitive rest: Limit or avoid schoolwork, reading, screen time (phones, computers, TV, video games), texting 1
• Environmental modifications: Sunglasses for photophobia, avoid loud music/headphones for phonophobia 1
• Driving restriction: Reaction times are slowed; temporarily avoid driving 1

Critical rule: Never return to play the same day, even if symptoms resolve. "When in doubt, sit them out!" 1

School Accommodations

Coordinate with teachers and administrators for 1:

• Reduced workload and extended deadlines
• Frequent breaks during classes
• Quiet testing environment
• Gradual reintegration as tolerated

Teachers often underestimate difficulties because the student "looks fine"—proactive education is essential 1.

Return-to-Activity Protocol

Once asymptomatic at rest for 24 hours, begin the stepwise progression. Each stage takes minimum 24 hours; total minimum 5 days to return to full play 1:

1. Light aerobic activity: Walking, stationary cycling at <70% max heart rate; no resistance training 1
2. Sport-specific exercise: Running drills, skating—no head impact activities 1
3. Non-contact training drills: More complex drills, may start light resistance training 1
4. Full-contact practice: After medical clearance only 1, 5
5. Return to game play 1, 5

If any symptoms return at any stage: Stop activity, rest 24 hours until asymptomatic, then retry the previous stage 1, 5, 1.

Recovery Timeline and Red Flags

• Expected recovery: 7-10 days for most adolescents 1
• Adolescents recover slower than college/professional athletes—be more conservative 1
• Prolonged symptoms: If symptoms persist beyond 4-6 weeks, refer to concussion specialist 4
• Consider specialist referral if: 3+ concussions in one season, symptoms >3 months, or uncertainty about return-to-play timing 1

Evidence on Active Rehabilitation

Recent evidence supports early active rehabilitation over prolonged strict rest 2:

• After initial 24-48 hour rest period, prescribed sub-symptom threshold aerobic exercise (light activity that doesn't worsen symptoms by >2 points on 0-10 scale for >1 hour) accelerates recovery by mean 4.64 days 2
• Early return to light physical activity and reduced screen time, followed by prescribed aerobic exercise within 14 days, reduces risk of persistent symptoms beyond 30 days 2

Common Pitfalls to Avoid

• Don't use "cocooning" (strict rest until complete resolution)—this delays recovery 2
• Don't rely on neuroimaging to make the diagnosis—it's clinical 1
• Don't use medications routinely—safety and efficacy not established in sport-related concussion 1
• Don't allow same-day return to play even if asymptomatic—this is dangerous 1
• Don't skip visio-vestibular examination—dysfunction predicts prolonged recovery 2, 3

When to Obtain Neuropsychological Testing

Neuropsychological testing provides objective data but does not alone diagnose concussion or determine return-to-play readiness 1. It's one tool among many in comprehensive management. Consider for athletes with prolonged symptoms or complex recovery 1.
