Sincope cardioinibitoria provocata da manovre di induzione di crisi psicogene

Induction procedures with placebo are useful for the differential diagnosis between epileptic seizures and psychogenic seizures. These procedures are highly sensitive and specific; they are inexpensive, rapid, simple and without risk. We collected 46 patients with psychogenic seizures. We obtained video-EEG recordings of a psychogenic attack, provoked by induction procedures, in 45 patients. Placebo infusion provoked a cardioinibitory syncope in one case. During placebo infusion we recommend EKG monitoring in order to avoid possible risk for the patient.
