Non-convulsive status epilepticus is a significant issue for a neurologist
because, despite its low prevalence, it mimics other pathologies, with
therapeutics and prognostic outcomes. Diagnosis is based on clinical features,
mainly mental status or impaired consciousness and electroencephalographic
changes, so electroencephalogram is the first exploration we must perform with
clinical suspicion. There are three clinical forms: generalized or absence
status, with diffuse epileptiform discharges; focal, with epileptic discharges
located in a specific brain area and may not affect consciousness; and subtle,
with diffuse or local epileptic activity after a tonic-clonic seizure or
convulsive status and limited or no motor activity. Treatment are benzodiazepines
and antiepileptic drugs; anesthetic drugs are only recommended for patients with
subtle status and in some with partial complex status. Prognosis is mainly
determined by etiology and associated brain damage.
