Nonconvulsive status epilepticus: etiology, clinical features and prognosis

The clinical features of non-convulsive status epilepticus (NCSE) can vary from minimal and highly subtle, to coma. A classification of NCSE is presented which includes genetic types of typical absence status, non genetic atypical NCSE as seen in Lennox-Gastaut Syndrome, and the rarer types of generalized status epilepticus. The clinical features of localization related status epilepticus may vary from sensory, motor, autonomic with or without perturbation of vigilance and consciousness, and other rarer features which will be presented descriptively and in tabular form. I discuss approaches to diagnosis, management and treatment, as well as prognosis.
