Non-convulsive status epilepticus (NCSE) has a wide range of clinical presentations, ranging from confusion to coma accompanied by many kinds of continuous or recurrent epileptic discharges on electroencephalogram (EEG). It may occur not only in epileptic patients, but also in adults with no previous history of epilepsy. EEG is the only reliable method of diagnosis. Identification may be particularly difficult, and consequently, a high level of suspicion is essential for early diagnosis. Delay in diagnosis may increase morbidity and mortality. This report presents a case in which the patient’s NCSE was due to infection.
