Psychological and trauma-related differences in psychogenic nonepileptic seizures: An exploratory severity-based...

Area of Science:

• Neuroscience
• Psychiatry
• Clinical Psychology

Background:

• Psychogenic nonepileptic seizures (PNES) are characterized by psychological and trauma-related factors.
• Distinguishing psychosocial patterns based on PNES severity is essential for targeted interventions.
• Comparison groups include epilepsy patients and healthy controls to contextualize findings.

Purpose of the Study:

• To examine psychological and trauma characteristics in patients with psychogenic nonepileptic seizures (PNES).
• To explore if clinically informed severity groupings reveal distinct psychosocial patterns in PNES.
• To compare PNES patients with epilepsy and healthy control groups.

Main Methods:

• Participants comprised mild PNES (n=20), severe PNES (n=28), epilepsy (n=48), and healthy controls (n=50).
• Assessments included measures of anxiety, depression, childhood trauma, dissociation, somatization, and alexithymia.
• PNES severity was determined by clinical indicators like healthcare utilization and seizure intensity.

Main Results:

• Both mild and severe PNES groups reported higher anxiety than controls (p < .01).
• Depression scores were highest in mild PNES (p < .05).
• Trauma profiles differed by severity: sexual abuse in mild PNES, physical abuse and emotional neglect in severe PNES (p < .05). Mild PNES also showed higher dissociation, somatization, and alexithymia.

Conclusions:

• PNES severity correlates with specific trauma histories and psychological symptom clusters.
• Findings underscore the importance of individualized psychological assessments for PNES patients.
• Further research is needed to validate severity-based distinctions in PNES management.
