Baslet G, et al. - The physicians tested the hypothesis that altered responsiveness was associated with difficulties with emotion tolerance, experiential avoidance, difficulty coping, dissociation and trauma and prior experiences of loss of awareness. During psychogenic nonepileptic seizures (PNES), altered responsiveness was a marker of lower emotional resilience or ability to tolerate emotions among patients with PNES. For these patients, emotion management could be an important therapeutic target. Furthermore, prior experiences with loss of consciousness (LOC) contributed to the presence of altered responsiveness. During PNES, trauma and dissociation did not differentiate responsiveness.
