Management of Psychogenic Non-Epileptic Seizures (Pseudoseizures)
The management of psychogenic non-epileptic seizures (PNES) should focus on cognitive behavioral therapy as the primary intervention, along with clear communication about the diagnosis in a sympathetic manner that acknowledges the involuntary nature of the attacks. 1
Diagnostic Considerations
- PNES is considered a conversion disorder—an external somatic manifestation in response to internal psychological stresses
- Key clinical features suggestive of PNES:
- Often affects young females
- Higher prevalence of preexisting vasovagal syncope
- History of physical and/or sexual abuse
- Apparent loss of consciousness often lasting longer (5-20 minutes)
- Frequent episodes
- Closed eyes during episodes (unlike epileptic seizures)
- Lack of pallor and diaphoresis
- Usually little physical harm
- Normal pulse, blood pressure, or EEG during episodes 1
Management Approach
1. Clear Diagnosis Communication
- Candid discussion with the patient about the diagnosis in a clear but sympathetic manner
- Acknowledge the involuntary nature of the attacks
- Avoid terminology that may cause confusion (e.g., "seizure" without clarification) 1
- Use "psychogenic non-epileptic seizures" or "psychogenic pseudosyncope" rather than "psychogenic syncope" (which is pathophysiologically incorrect) 1
2. Psychological Interventions
- Cognitive behavioral therapy (CBT) is the primary recommended treatment 1
- Uncontrolled studies suggest psychotherapy, particularly CBT, may be beneficial
- One RCT showed a non-statistically significant trend toward improvement at 3 months 1
3. Multidisciplinary Management
- Psychiatric evaluation to identify and address:
4. Medication Considerations
- There is no evidence supporting significant benefit from pharmacotherapy specifically for PNES 1
- Address underlying psychiatric comorbidities if present:
Common Pitfalls and Caveats
- Misdiagnosis: PNES is often misdiagnosed as epilepsy, leading to unnecessary and potentially harmful medical interventions 4
- Dual diagnosis: Some patients may have both epileptic seizures and PNES
- Medication management: Supervised withdrawal of antiepileptic medications may be appropriate when no epilepsy is present 4
- Prognosis: With proper diagnosis and treatment, freedom from pseudoseizures can be achieved in up to 72% of patients, with many becoming symptom-free within one month of diagnosis 2
Special Considerations
- Higher psychiatric comorbidity in PNES compared to epileptic seizures (RR: 1.30,95% CI: 1.14-1.48) 3
- Recent research supports a multidisciplinary, holistic approach to improve quality of life even when complete seizure freedom is not achieved 5
- Early therapeutic counseling should be initiated promptly after diagnosis to address underlying psychological factors 6
By following this management approach, clinicians can effectively address both the psychological factors underlying PNES and improve patients' quality of life while avoiding unnecessary medical interventions.
