Frequency of non convulsive Status Epilepticus in patients with impaired level of consciousness.
J Pak Med Assoc Jan ;59(5):296-8.

Objective: To determine the frequency of Non Convulsive Status Epilepticus in patients admitted with impaired consciousness. Methods: All EEG`s in patients with impaired level of consciousness over four years from 2002- 2006 were reviewed. All EEG`s showing continuous epileptiform discharges were included. Findings of all these EEG`s were divided into five groups; generalized spikes and wave, generalized sharp and wave, focal spike and wave, focal sharp and wave and periodic lateralized epileptiform discharges. Results: There were 785 EEG`s recorded in patients with impaired level of consciousness. Only 12 (1.5%) patients were identified with NCSE on EEG. The commonest EEG findings in our patients with NCSE were: Continuous focal spike and wave seen in 4(33%), Continuous generalized spike and wave 3 (25%), Continuous generalized sharp and wave 3 (25%), Continuous focal sharp and wave 1 (8.3) and Continuous periodic lateralized epileptiform discharges (PLEDs) in 1 (8.3%) patient. Conclusion: NCSE is an important treatable entity which can be easily recognized by doing an EEG (JPMA 59:296; 2009).
