Heat stroke includes neurologic impairment as a person's body temperature reaches 40.5 degrees C (105 degrees F) as a result of a failure of thermoregulation. The physiologic complications of heat stroke are well described in the literature. The domains of cognitive functioning affected and the severity of impairment resulting from heat stroke can vary from mild deficits in attention and memory to severe global dementia. There can also be changes in affect and personality that are equally debilitating. This article presents the neuropsychological test results of three active duty soldiers who suffered heat stroke and were tested within 2.5 months of injury.
