Treatment of nonepileptic seizures.

Studies on nonepileptic seizures (NES) provide dichotomous data sets: extensive observational findings, but a paucity of controlled treatment data. Psychosocial stressors, whose full impact may lie outside a patient's awareness, often underlie NES. These stressors, along with patient's learned patterns of coping, may bring forth or potentiate comorbid psychiatric disorders. Patients with NES often have dysfunction in emotion regulation and family dynamics, as well as unemployment/disability. High percentages of comorbid disorders such as major depressive disorder, post-traumatic stress disorder, and cluster B personality with impulsivity (all disorders associated with serotonin system function) also exist in the NES population. The preliminary observational evidence suggests that specific psychotherapies and pharmacotherapy directed at comorbid conditions may be the most effective treatment for NES.
