Two case reports of epileptic seizures related to-probable cerebral arterial gas embolism

Two cases are presented of divers suffering epileptic seizure and loss of consciousness as a result of probable cerebral arterial gas embolism (CAGE). Both cases had apparently problem-free dives with no obvious provocation for CAGE, though one case may have been having repeated embolisms for some time in their diving career. Demonstrated also is the Type III form of decompression sickness, where spinal cord disease follows CAGE in a biphasic manner.
