Initial Management Approach for Functional Neurological Disorder with Parkinson's-like Motor Symptoms
Diagnostic Approach
- Establish a positive diagnosis based on clinical features rather than treating FND as a diagnosis of exclusion 3
- Look for positive clinical signs specific to FND, such as symptoms inconsistent with clinical examination findings, internal inconsistency in symptoms, and inefficient movement patterns 4
- Consider neuroimaging to rule out structural causes, especially when symptoms are atypical or rapidly progressive 5
- Document the presence of distractibility and variability of symptoms during functional activities 6
Explaining the Diagnosis
- Acknowledge that FND is a real, common, and disabling condition causing neurological symptoms that are outside the person's voluntary control 6
- Explain that FND is caused by a potentially reversible miscommunication between the brain and body, not structural damage 6
- Use supportive and accessible metaphors to explain the condition, such as "a software problem, not a hardware problem" 2
- Discuss how self-directed attention can worsen symptoms while redirection of attention can temporarily reduce symptoms 6
Treatment Framework
Physical Rehabilitation
- Implement guided activity practice focusing on normal movement patterns 6
- Use distraction techniques during movement to demonstrate normal function, such as introducing additional activities to shift attention away from performance 2
- Establish a graded exercise program that gradually increases in complexity 6
- Focus on improving function rather than symptom reduction 6
Psychological Interventions
- Address cognitive features related to locus of control, abnormal illness beliefs, and hypervigilance 1
- Implement cognitive behavioral therapy strategies to identify and challenge maladaptive beliefs and cognitions 1
- Teach anxiety management techniques, such as breathing techniques and progressive muscle relaxation 7
Managing Comorbidities
- Consider medication for specific symptoms, such as SSRIs for anxiety and depression 1
- Consider low-dose amitriptyline for pain and sleep disturbances 1
Multidisciplinary Approach
- Implement a coordinated team approach including occupational therapy for functional activities and daily living skills 6
- Include speech and language therapy for communication difficulties 1
Important Considerations and Pitfalls
- Avoid reinforcing abnormal movement patterns or excessive focus on symptoms 2
- Recognize that early treatment is crucial, even when other FND symptoms are present 2
- Understand that patient acceptance of the diagnosis is important for treatment success, but some patients may only embrace the diagnosis during successful treatment 2
- Avoid excessive medical investigations once a positive diagnosis is established, as this can reinforce illness beliefs 6
Expected Outcomes
- Many patients show improvement or even elimination of symptoms during initial consultations 3
