About this study

Altered mental status (AMS) is one of the most common reasons for inpatient neurology consultation. Non-convulsive status epilepticus (NCSE) is frequently on the differential diagnosis of the patient with AMS. NCSE becomes more refractory to treatment after one hour of seizure activity, making rapid identification and treatment of NCSE of great clinical importance. Currently, an electroencephalogram (EEG) technologist must be called in from home during non-workday hours in order to obtain a stat EEG. The investigators propose the time required for diagnosis of NCSE at Mayo Clinic can be significantly decreased with rapid placement of an EEG cap by the onsite neurology residents.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
