In a single month, there were three patients admitted to our institution for profound unresponsiveness in whom the full workup during the episode, including routine laboratory tests, toxicology screen, electrocardiogram, arterial blood gases, spinal tap, electroencephalogram, computed tomographic scans, and magnetic resonance imaging, revealed negative results.

The full workup, excluding spinal tap and magnetic resonance imaging, was repeated in both patients, again failing to explain the unresponsiveness. A repeated electroencephalogram done during the episode showed only
