[Status Epilepticus: Convulsive and Nonconvulsive]

Status epilepticus(SE)is common, particularly among neurological emergency physicians. SE includes convulsive SE(CSE)and nonconvulsive SE(NCSE). Recently, the number of elderly patients with status epilepticus has increased. Most patients were diagnosed with NCSE. Prolonged SE often impairs neuronal function and is sometimes life threatening. Prompt diagnosis of SE and treatment initiation are essential for good outcomes. However, an accurate diagnosis of NCSE is difficult because the clinical symptoms of NCSE may vary, and electroencephalography may show various characteristics. Recent advances in the diagnosis and treatment of SE have been reported, particularly with regard to electroencephalography(EEG)and newly available drugs.
