Associations between violent and sexual childhood trauma and maladaptive coping in patients with functional seizures.

Objective: Functional seizures (FS) are a highly debilitating symptom of functional neurological disorder (FND). FS requires a multi-disciplinary approach to treatment because the patient's initial presentation is to neurology, emergency medicine, or primary care and treatment consists of psychotherapy. People with FS commonly experience severe childhood trauma, particularly sexual trauma. The authors aimed to investigate associations between reported trauma and maladaptive coping mechanisms in the FS population.

Methods: This retrospective, observational study reports on 137 patients enrolled in the FS Clinic at the University of Colorado between March 2020 - March 2021. Multiple linear regression was used to reveal associations between self-reported childhood sexual and violent trauma and maladaptive coping mechanisms of self-blame and disengagement on the Brief COPE. A quantile regression was generated for each of these outcomes.

Results: Results showed that violent and sexual trauma were experienced by 47.5% and 61.6% of the population sample, respectively. Of those exposed to violent trauma, 27.2% perceived it as extremely severe while 43.4% of those exposed to sexual trauma perceived it as extremely severe. Quantile regressions for self-blame and disengagement showed significance for the 25^th percentile of those who experienced violent trauma. Self-blame was significantly associated with the 50^th and 75^th percentile of those exposed to sexual trauma.

Conclusions: This evidence supports the value of identifying trauma experienced by individuals with FS as it is associated with specific coping mechanisms that may affect treatment. Identifying prior trauma and resulting coping mechanisms can potentially assist in individualizing care for people with FS.
