Post-Concussion Syndrome Management

Introduction to Post-Concussion Syndrome

The American College of Physicians recommends that post-concussion syndrome should be actively managed with graded physical exercise, vestibular rehabilitation for dizziness, and interdisciplinary treatment rather than prolonged rest 1

Post-concussion syndrome develops from a neurometabolic cascade triggered by biomechanical forces to the brain, creating increased local energy demand in the presence of decreased cerebral blood flow and mitochondrial dysfunction, affecting approximately 15-20% of concussion patients 2
Most adults recover within 3 to 12 months post-injury, with patients presenting with headache, nausea, and dizziness in the emergency department having a 50% chance of developing persistent symptoms at 6 months 3

The American Academy of Neurology recommends implementing graded sub-symptom threshold aerobic exercise as the cornerstone of treatment, with physical exercise having positive effects on overall symptom burden, physical functioning, emotional symptoms, and quality of life 6, 1
Vestibular rehabilitation, including otolith manipulating procedures, habituation and adaptation exercises, substitution training, and balance training, has demonstrated positive effects on physical functioning and return to activities 6, 1
Interdisciplinary coordinated rehabilitation involving at least two different healthcare disciplines is recommended for patients with multiple persistent symptoms, with positive effects on overall symptom burden, physical functioning, emotional symptoms, and quality of life 6, 1

For persistent vestibular symptoms, provide vestibular rehabilitation at least once weekly for 4 weeks 6, 1
For visual symptoms, implement oculomotor vision treatment, including vergence training, accommodative training, and eye movement exercises 1
For neck pain and cervicogenic headache, provide spinal mobilization and manipulation of the neck and spine, with positive effects on pain reduction and readiness to return to activities 6, 1
For emotional symptoms, offer individual or group psychological treatment, associated with positive effects on overall symptom burden, emotional symptoms, and quality of life 6, 1

The available evidence ranges from very low to low certainty, primarily due to risk of bias, small sample sizes, and limited number of studies, but the recommendation for active management is consistent across all available guidelines regardless of methodology 6, 8
