Nonconvulsive status epilepticus associated with leptomeningeal carcinomatosis and positive SOX1 antibodies

Nonconvulsive status epilepticus (NCSE) is a disorder with varying prognoses depending on the underlying etiology.NCSE is increasingly recognized as a cause of altered mental status or coma and accounts for 25% of all cases of status epilepticus.NCSE is difficult to diagnose without continuous electroencephalogram (EEG) monitoring.NCSE due to paraneoplastic autoimmune encephalitis associated with SOX1 antibodies has been rarely reported.
