What is the main cause of psychogenic non-epileptic seizures?
Appeared in: UP NHM CHO 7 Sept 2022 (Shift-2)
Explanation
- Psychogenic non-epileptic seizures (PNES) are physical manifestations of psychological distress.
- They are classified as a functional neurological symptom disorder (conversion disorder), where emotional conflict is 'converted' into physical symptoms.
- Triggers are often related to severe stress, trauma, or underlying psychiatric conditions like PTSD or depression.
- Unlike epileptic seizures, PNES are not caused by any structural brain abnormality or abnormal electrical discharges.
Why Other Options Were Wrong
- Option A: Immediate brain injury can cause post-traumatic epilepsy, which involves true epileptic seizures due to structural damage and abnormal electrical discharges, not psychogenic seizures.
- Option C: This is the defining cause of epileptic seizures. In PNES, the electroencephalogram (EEG) is normal during an event, confirming the absence of abnormal brain discharges.
- Option D: This is a vague, non-medical term. While PNES involves the mind affecting the body, 'brain-body disconnection' does not accurately describe the established etiology, which is rooted in psychological processes.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Etiology of Psychogenic Non-Epileptic Seizures (PNES) as background academic context rather than a clinical decision trigger.
- Accurate diagnosis of PNES is critical to prevent inappropriate and ineffective treatment with antiepileptic drugs (AEDs), which have significant side effects and do not treat PNES.
- The gold standard for diagnosis is video-EEG monitoring, which simultaneously records the patient's behavior and brain electrical activity to confirm the absence of epileptic discharges during a typical event.
- Management requires a compassionate, non-judgmental approach and a multidisciplinary team, including neurologists and mental health professionals, to address the underlying psychological distress.
How to Approach the Question
- First, identify the core subject of the question: 'psychogenic non-epileptic seizures' (PNES).
- Break down the term: 'Psychogenic' means originating in the mind or from psychological factors. 'Non-epileptic' means not caused by the abnormal brain activity that defines epilepsy.
- Analyze the options based on this definition.
- Option A (brain injury) and C (abnormal brain discharge) relate to the causes of true epileptic seizures. Eliminate them.
- Option D (brain-body disconnection) is a vague, non-specific term. Option B (psychological/emotional processes) directly matches the meaning of 'psychogenic'.
- Select the option that aligns with the definition of a psychogenic condition.
