Diagnostic Procedure and Therapeutic Approaches in Nonconvulsive Status Epilepticus (NCSE)

Nonconvulsive epileptic seizures are major type of seizures of all patients with predominantly focal epilepsy. However, this problem is still insufficiently studied, the literature presents a few data on the diagnosis and treatment of nonconvulsive status epilepticus (NCSE). NCSE is a prolonged seizure, not accompanied by severe motor presentation. Such attacks occur much more often than previously thought. NCSE is divided into focal NCSE (complex partial status epilepticus), and generalized NCSE, often referred as absence status. The absence status divides into a typical absence status (presents with suppression of consciousness of various depths, myoclonic twitching of the eyelids, impoverishment of speech production and hallucinations), atypical absence status (presents with retardation of mental processes and eyelid myoclonus) and late absence status (long-term disorientation accompanied by cognitive deficiency and presents mainly in elderly patients). According to the available sources, more than 30% of patients in the intensive care units with impaired consciousness of unclear genesis are patients with NCSE. Use of antiepileptic drugs for intravenous administration opens better opportunities in the treatment of patients with status epilepticus and NCSE.
