Neuron-specific enolase (NSE) is a sensitive marker of brain injury after stroke, global ischemia, and coma. We report changes in serum NSE (s-NSE) in 19 patients who sustained status epilepticus. s-NSE peaked within 24 to 48 hours after status epilepticus. The mean peak s-NSE level for the entire group was elevated compared with the levels for normal controls (24.87 ng/ml versus 5.36 ng/ml, p = 0.0001) and for epileptic controls (24.87 ng/ml versus 4.61 ng/ml, p = 0.0001). The mean peak s-NSE level for the 11 subjects without an acute neurologic insult (15.44 ng/ml) was also significantly increased compared with levels for normal and epileptic controls. Further, s-NSE was significantly correlated with outcome and duration. We conclude that s-NSE is a promising in vivo marker of brain injury in status epilepticus and warrants further study in larger populations.

D013226 Status Epilepticus A prolonged seizure or seizures repeated frequently enough to prevent recovery between episodes occurring over a period of 20-30 minutes. The most common subtype is generalized tonic-clonic status epilepticus, a potentially fatal condition associated with neuronal injury and respiratory and metabolic dysfunction. Nonconvulsive forms include petit mal status and complex partial status, which may manifest as behavioral disturbances. Simple partial status epilepticus consists of persistent motor, sensory, or autonomic seizures that do not impair cognition (see also EPILEPSIA PARTIALIS CONTINUA). Subclinical status epilepticus generally refers to seizures occurring in an unresponsive or comatose individual in the absence of overt signs of seizure activity.
