Neuron-specific enolase is increased after single seizures during inpatient video/EEG monitoring.
Neuron-specific enolase (NSE) is a marker of brain injury after acute neurologic insults. We report changes in serum NSE (s-NSE) in 25 patients (15 with epilepsy and 10 patients with nonepileptic events) during continuous inpatient video/EEG monitoring. s-NSE was significantly increased as compared with baseline and normal controls after the first ictal event in the epileptic group, especially in patients with secondarily generalized tonic-clonic seizures (p = 0.01), but s-NSE was not increased in patients with nonepileptic events. These preliminary data indicate that s-NSE may be increased after complex partial seizures--and generalized tonic-clonic seizures (GTCS).
