How should post-concussion syndrome be managed in an adult with persistent headache, dizziness, sleep disturbance, concentration, or mood symptoms beyond two weeks?

Management of Post-Concussion Syndrome in Adults

Adults with persistent post-concussion symptoms beyond two weeks should receive a multimodal, symptom-targeted rehabilitation approach that includes early education and advice, graded aerobic exercise, and specific therapies directed at their predominant symptom profile (vestibular, cervical, visual, or psychological). 1

Initial Management: Early Education and Advice

• Provide systematic education within the first 4 weeks after injury to reduce overall symptom burden and prevent progression to persistent symptoms 1
• Education should include information about expected symptom patterns, self-management strategies, and reassurance about typical recovery trajectories 1
• This intervention reduces memory problems and minimizes impact on work and leisure activities at 2 weeks post-intervention 1
• The evidence quality is very low due to risk of bias and imprecision, but no serious adverse effects have been reported 1

Core Intervention: Graded Aerobic Exercise

• Implement graded physical exercise as a foundational treatment for persistent symptoms, starting at sub-symptom threshold intensity (70-80% of heart rate at symptom exacerbation) 2, 3
• Exercise should be performed at least once weekly for a minimum of 4 weeks, with gradual increases in intensity and complexity over time 1
• This intervention improves overall symptom burden, physical functioning, behavioral reactions, emotional symptoms, quality of life, and work satisfaction 1
• Graded aerobic exercise has demonstrated effectiveness in reducing exercise intolerance, which affects up to 30% of individuals with persistent post-concussive symptoms 2

Symptom-Specific Targeted Therapies

For Dizziness and Vestibular Dysfunction

• Offer vestibular rehabilitation including otolith manipulation, habituation exercises, adaptation exercises, substitution training, and balance training at least once weekly for 4 weeks 1
• This reduces overall symptom burden and vestibular dysfunction specifically 1
• Vestibular rehabilitation improves readiness to return to sport and daily activities 1

For Headache and Neck Pain

• Provide spinal manual therapy (mobilization and/or manipulation of the cervical spine and back) performed by physiotherapists or chiropractors 1
• Manual therapy reduces pain and improves physical functioning 1
• This intervention increases the number of patients ready to return to sport after completion 1
• Treatment should be administered at least once weekly for a minimum of 4 weeks 1

For Visual Symptoms

• Refer patients with persistent visual complaints for oculomotor vision treatment including vergence, accommodative, and eye movement dysfunction training 1
• While no high-quality trials exist, clinical experience demonstrates that oculomotor therapy improves visual symptoms and reduces associated headache and fatigue 1
• Treatment should include computer-based training or optometric instrumental training at least once weekly for 4 weeks 1

For Mood, Concentration, and Sleep Disturbances

• Initiate psychological treatment by psychologists or similarly trained clinicians for at least 1 hour weekly as individual or group therapy for a minimum of 4 weeks 1
• Psychological interventions reduce the collective burden of post-concussion symptoms and improve emotional symptoms at 3 months post-intervention 1
• Consider cognitive behavioral therapy specifically, which has demonstrated effectiveness for persistent symptoms 4
• Address comorbid conditions systematically: up to one-third of patients may have depression, one-quarter may have insomnia, and anxiety and cognitive issues are common 5

Comprehensive Interdisciplinary Approach for Complex Cases

• For patients with multiple persistent symptoms, implement interdisciplinary coordinated rehabilitation involving at least 2 different health disciplines collaborating on treatment 1
• This should combine multiple interventions (vestibular rehabilitation, graded exercise, oculomotor therapy, manual treatment, psychological intervention, and vocational rehabilitation) 1
• Treatment must be administered at least once weekly for a minimum of 4 weeks 1
• The interdisciplinary approach is particularly important given that 15-20% of patients develop persistent symptoms, with potentially higher rates when objective cognitive assessments are used 1

Critical Caveats and Pitfalls

• Avoid strict bed rest, which has been found ineffective or potentially detrimental in randomized controlled trials 1
• Do not prescribe intense physical activity too early, as this can worsen symptoms 1
• Recognize that persistent symptoms are nonspecific and may be attributable to preexisting conditions, coexisting disorders, or other factors beyond the concussion itself 1
• Preexisting mood disorders and high initial symptom load are the most consistent predictors of persistent symptoms in adults 1
• Screen for treatable comorbidities including post-traumatic headache, depression, anxiety, sleep disorders, and vestibular dysfunction, as many patients with persistent symptoms have conditions amenable to targeted treatment 1, 5
• All recommendations carry very low certainty of evidence due to risk of bias, indirectness, and imprecision across studies 1

Pharmacological Considerations

• While few studies specifically examine pharmacology for post-concussion syndrome, targeted medication treatment may be warranted for symptoms that persist or significantly impair quality of life 6
• For post-traumatic headache specifically, topiramate may be more effective than other oral preventive medications based on recent studies 5
• Other investigated treatments for headache include nerve blocks, onabotulinum toxin A, and transcranial magnetic stimulation 5
