Post-Concussion Syndrome Management

Immediate Management Approach

The American Academy of Pediatrics recommends beginning sub-symptom threshold aerobic exercise immediately, rather than strict rest, as complete rest beyond 2-3 days may actually delay recovery 1, 2
Start with light aerobic activity at 60-70% of maximum heart rate for 15-20 minutes daily, and gradually increase activity duration and intensity as tolerated over subsequent days 1
Implement partial cognitive rest rather than complete avoidance of all mental activity, reducing screen time to 30-minute intervals with breaks, limiting reading, and considering shortened work/school days with reduced workload 2

For headache management, continue acetaminophen as first-line, optimizing dosing to 650-1000mg every 6 hours as needed, with a maximum of 4000mg/24 hours, and consider adding an NSAID if acetaminophen alone is insufficient 4
Do not use opioids or butalbital-containing medications for headache management, as they are contraindicated and may worsen outcomes 4

Instruct the patient to return immediately if they experience repeated vomiting, worsening or severe headache, increasing confusion, focal neurologic deficits, abnormal behavior, increased sleepiness, or seizures 3, 5

Refer to a concussion specialist or sports medicine physician if symptoms persist beyond 3 weeks, significantly worsen despite conservative management, or if the patient plans to return to contact sports 3, 5, 6

Most patients (80-85%) recover completely within 3 months, while persistent symptoms beyond 3 months occur in 15-20% of patients and constitute post-concussion syndrome 1, 5, 8
Risk factors for prolonged recovery include female gender, age >40 years, prior concussion history, high initial symptom burden, and pre-existing mood disorders 1, 8

Do not prescribe strict bed rest or complete activity restriction beyond the first 48-72 hours, as this may prolong recovery 1, 2
Do not use medications to mask symptoms to allow premature return to activities, as any medication used to control symptoms indicates incomplete recovery 2
Do not discharge without written instructions at a 6th-7th grade reading level given to both patient and caregiver 3, 5
