📚 What is a Concussion?
A concussion is a type of mild traumatic brain injury (mTBI) caused by a bump, blow, or jolt to the head, or by a hit to the body that causes the head and brain to move rapidly back and forth. This sudden movement can cause the brain to bounce around or twist inside the skull, creating chemical changes and sometimes stretching and damaging brain cells.
Key Facts About Concussions
🔍 Often Invisible
- You can't see a concussion
- Most concussions do NOT cause loss of consciousness

- Girls have higher rates in soccer and basketball
- Can occur in any activity
⏱️ Recovery Time
- Most recover within 2-4 weeks
- Teens may take longer than adults
- Each concussion is unique
⚡ Brain Changes
- Chemical changes occur in the brain
- Brain needs extra energy to heal
- Blood flow to brain temporarily decreases

📅 Recovery Timeline
Recovery from a concussion follows a gradual progression. The key is to balance rest with gradual return to activities.
First 24-48 Hours: Initial Rest Period
During this acute phase, focus on:
- Reducing physical and cognitive activities
- Limiting screen time (total of ~130 minutes or less)
- Getting adequate sleep - it's okay to sleep!
- Avoiding any activities that could cause another head injury
- Light activities like short walks are generally okay
Days 2-7: Gradual Return to Activities
After initial rest, begin gradually increasing activity:
- Start with short periods of light cognitive activity (15-20 minutes)
- Take breaks when symptoms increase
- Light physical activity like walking is encouraged
- Most students can return to school within 1-2 days with accommodations
- Avoid activities that worsen symptoms significantly
Weeks 1-4: Progressive Recovery
Continue gradual progression:
- Increase school attendance and workload as tolerated
- Begin light aerobic exercise if cleared by healthcare provider
- Most symptoms should improve during this time
- Continue to monitor for symptom changes
Beyond 4 Weeks: If Symptoms Persist
If symptoms last longer than 4 weeks:
- This is considered "persistent symptoms" requiring follow-up
- Consult with a concussion specialist
- May need referral to neuropsychologist or other specialists
- Formal accommodations (504 Plan) may be needed at school
🏃 6-Step Return to Sports Progression
Athletes should only return to sports with approval from a healthcare provider. The CDC recommends this 6-step graduated return to play protocol. Each step should take a minimum of 24 hours.
Back to Regular Activities
Return to normal non-sports activities (like school). No sports activities yet. Must be symptom-free at rest before starting step 2.
Light Aerobic Exercise
5-10 minutes of walking, swimming, or stationary cycling at light intensity. No weight lifting or resistance training. Goal is to increase heart rate.
Sport-Specific Exercise
Running drills, skating drills. Moderate intensity exercise with body/head movement. No head impact activities.
Non-Contact Training Drills
More complex training drills. May start progressive resistance training. No contact with other players.
Full Contact Practice
Following medical clearance, participate in normal training activities including contact. Restore confidence and assess functional skills.
Return to Competition
Normal game play. Full return to sports without restrictions.
⚠️ Important Rules
- Stop and go back one step if symptoms return or worsen
- Wait at least 24 hours at each step before moving forward
- Never return to play on the same day as a concussion
- Get written clearance from a healthcare provider before returning to contact sports
📖 Returning to School
Most students can return to school within 1-2 days after a concussion, though they may need temporary adjustments. Research shows that returning to school (with appropriate support) can actually help recovery and reduce the risk of mental health symptoms.
Common Academic Accommodations
- Extended time for assignments and projects
- Reduced homework load
- Postponed or staggered tests
- Shortened school days if needed
- Prioritize essential assignments
- Extended test-taking time
- Quiet room for testing
- Tests given in shorter segments
- Oral testing instead of written
- Option to postpone major exams
- Rest breaks in a quiet area (like the nurse's office)
- Preferential seating away from windows and bright lights
- Sunglasses allowed for light sensitivity
- Permission to leave noisy areas (cafeteria, assemblies)
- Reduced screen time in class
- Copy of class notes provided
- Audio recording of lectures permitted
- Buddy system for missed notes/assignments
- Check-ins with school nurse or counselor
- Tutoring support if needed
- Excused from PE until cleared
- Modified recess activities (no contact)
- Elevator pass if stairs cause symptoms
- Early release from classes to avoid crowded hallways
Tips for Students
- Communicate: Let your teachers and school nurse know about your concussion
- Ask for the CDC HEADS UP Letter to Schools from your healthcare provider
- Take breaks when symptoms increase - this is not being "weak"
- Don't try to catch up all at once - gradual return is better
- Stay connected with friends and classmates
💡 Daily Recovery Tips
