title: [Bipolar head injury with global amnesia].
abstract: We report the first case of bipolar head injury, that is, subsequent head injuries sustained near both poles of the Earth. The injury caused a true global amnesia with loss of memory for the journey around the globe. This case history illustrates how modern emergency services have reduced the hazards of polar exploration, and how a second impact after a primary head injury may cause life-threatening complications.
