Insecure and Unresolved/Disorganized Attachment in Patients With Psychogenic Nonepileptic Seizures.

BACKGROUND

Psychogenic nonepileptic seizures (PNES) are still poorly understood and difficult to treat. Attachment theory could add new aspects to the understanding of the multifactorial genesis and maintenance of PNES and the therapeutic needs of this patient group.

OBJECTIVE

The aim of the present study is to systematically assess attachment in adult patients with PNES with a focus on the role of unresolved/disorganized attachment.

METHODS

A cross-sectional design was chosen to compare patients with confirmed PNES (n = 44) and healthy controls (n = 44) matched for gender, age, and education. Attachment was assessed using the Adult Attachment Projective Picture System. Psychometric questionnaires included the Childhood Trauma Questionnaire; Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) axis II disorders, Patient Questionnaire; the Somatoform Dissociation Questionnaire; and the Patient Health Questionnaire.

RESULTS

We found significantly less secure (P = 0.006) and more unresolved/disorganized (P = 0.041) attachment classifications in the PNES group. Among patients with PNES, 7% were classified secure and 43% were classified unresolved/disorganized. Patients with an unresolved attachment representation were significantly more likely to be screened positive for personality pathology in the Structured Clinical Interview for DSM-IV axis II disorders, Patient Questionnaire (P = 0.03) and to report more emotional abuse in the Childhood Trauma Questionnaire (P = 0.007) than patients with other attachment classifications.

CONCLUSIONS

Our findings suggest that unresolved/disorganized attachment might be the predominant attachment style in patients with PNES and might be associated with more severe personality pathology. This could be of therapeutic relevance. The present study is the first to assess adult attachment in patients with PNES using a semi-structured interview in comparison to matched healthy controls.
