What is the medical management for a patient with persistent concussion symptoms, generalized anxiety disorder (GAD), and significant depressive symptoms?

Medical Management for Persistent Concussion Symptoms with GAD and Depression

For patients with persistent concussion symptoms complicated by generalized anxiety disorder and significant depressive symptoms, an interdisciplinary coordinated rehabilitative treatment approach is strongly recommended as the most effective management strategy to improve overall symptom burden, emotional symptoms, and quality of life.

Initial Assessment Components

• Evaluate the collective burden of postconcussion symptoms, including physical, cognitive, and emotional manifestations to establish baseline severity 1
• Conduct vestibular evaluation to identify dysfunction contributing to dizziness, balance problems, and visual disturbances 1
• Perform visual/oculomotor assessment to screen for vergence, accommodative, or eye movement dysfunction that may exacerbate headaches and concentration difficulties 1
• Complete cervical spine assessment to evaluate for cervicogenic contributions to headache and neck pain 1
• Conduct thorough psychological assessment focusing on anxiety, depression, and post-traumatic stress symptoms 1

Physical Interventions

• Implement graded physical exercise with sub-symptom threshold aerobic activity that gradually increases in intensity and complexity 2
  • Begin with 10-15 minutes of activity that doesn't worsen symptoms
  • Gradually increase duration and intensity as tolerated
  • Perform at least once weekly for a minimum of 4 weeks
• Provide vestibular rehabilitation for patients with persistent vestibular symptoms 2, 1
  • Include habituation exercises, adaptation exercises, and balance training
  • Administer at least once weekly for a minimum of 4 weeks
• Consider manual therapy for cervical spine if neck pain is present 2
  • Focus on mobilization and manipulation of the spine
  • Has shown positive effects on pain reduction and readiness to return to activities 1

Visual/Oculomotor Intervention

• Offer oculomotor vision treatment for persistent visual symptoms 1
  • Include vergence training, accommodative training, and eye movement exercises
  • Clinical experience suggests improvements in visual symptoms, headache, and fatigue 2
  • Particularly important as visual symptoms can exacerbate cognitive difficulties and anxiety 1

Psychological Interventions for GAD and Depression

• Provide psychological treatment through individual or group therapy 2, 1
  • Administer at least one hour weekly for a minimum of 4 weeks
  • Focus specifically on addressing both GAD and depressive symptoms
  • Cognitive-behavioral therapy has shown positive effects on emotional symptoms and quality of life 3
• Consider that anxiety and depression may persist for years after concussion and are associated with diminished quality of life 3
• Note that the number of previous concussions correlates with severity of anxiety and depression, suggesting an organic component 3

Comprehensive Approach

• Implement interdisciplinary coordinated rehabilitation involving at least two different healthcare disciplines working collaboratively 2, 1
  • This approach has demonstrated positive effects on overall symptom burden, physical functioning, emotional symptoms, and quality of life 4
  • Should include treatment of both the concussion symptoms and the comorbid anxiety and depression 2
• Provide systematic education and advice regarding symptom management, expected recovery course, and self-care strategies 2
  • Patient education has shown positive effects on reducing overall symptom burden 1

Important Considerations

• Persistent symptoms after concussion are often multifactorial and may be attributable to both the concussion itself and other factors 2
• Preexisting mood disorders and high initial symptom load are consistent predictors of persistent symptoms 2
• Depression and anxiety in persistent concussion symptoms can endure for years and significantly impact quality of life 3
• Early identification and treatment of depression and anxiety is crucial to optimize recovery 3
• The interdisciplinary approach has been found to reduce symptoms across all subtypes: headache/migraine, vestibular, cognitive, ocular motor, and anxiety/mood 4

Treatment Algorithm

1. First line: Begin with patient education and graded physical exercise 2, 1
2. Add symptom-specific treatments based on assessment findings:
   • For vestibular symptoms: Add vestibular rehabilitation 2
   • For visual symptoms: Add oculomotor vision treatment 1
   • For neck pain: Add manual therapy 2
3. For GAD and depression: Implement psychological treatment concurrently with physical interventions 2, 3
4. If symptoms persist: Escalate to full interdisciplinary coordinated rehabilitation 2, 4
