Spectrum of neurologic complications of lightning injuries.

Lightning is responsible for a wide spectrum of neurologic complications. Many of the persistent symptoms require long-term neurorehabilitation. The lightning-related neurologic conditions are divided into four categories. Category I consists of signs and symptoms that are temporary and usually benign. Category II conditions are prolonged or permanent produced by significant central nervous system lesions. Two of the most devastating complications are lightning-related encephalopathy and myelopathy. The disabilities that accompany these lesions call for concentrated neurorehabilitation. A large number of patients are afflicted with neurobehavioral symptoms that may last for months or years. Category III contains delayed neurologic syndromes. Category IV encompasses neurologic lesions that are not directly activated by the lightning strike but are the result of trauma secondary to falls or blasts effects. The sensible course for individuals at risk is to learn and follow lightning safety recommendations.
