Abstract
When a fixed set of ambient circumstances is associated with convulsive or nonconvulsive paroxysmal attacks, reenactment of the situation should be considered as a possible shortcut for reaching a diagnosis. Reenactment determined the diagnosis in 30 of 32 patients with paroxysmal disorders. The referral diagnosis was correct in only 13 of the 32 patients. To be appropriately executed, the reenactment should entail polygraphic recording of at least EEG, ECG, and respiration. Vertex electrodes should be included to avoid overlooking of cortical electrodecremental event. If unsuccessful at the 1st attempt, reenactment should be repeated.
