Symptomatic nonconvulsive status epilepticus erroneously suggestive of sporadic Creutzfeldt-Jakob disease

Nonconvulsive status epilepticus (NCSE) may have heterogeneous presentations and differential diagnosis may be particularly difficult because clinical signs coupled with periodic EEG pattern are most often subtle or non-specific. Moreover, few cases of NCSE have been previously described as the presenting symptom of sporadic Creutzfeldt–Jakob disease (sCJD) [1,4,5,7]. We describe a patient with a NCSE strongly, but erroneously, suggestive of a probable sCJD.
