Severe hypophosphatemia and acute neurologic dysfunction in a marathon runner.

摘要

The differential diagnosis of acute neurologic dysfunction in endurance athletes is broad but includes heatstroke, cerebrovascular accident, and electrolyte disturbance, among others. Although hyponatremia has been established as a reason for altered mental status (AMS) in endurance events, hypophosphatemia alone, to our knowledge, has not been reported as a cause of neurologic disturbance. We present a case of acute weakness and paresthesias mimicking stroke in a marathon runner with severe hypophosphatemia.
