Introduction
eEEG and non-convulsive status epilepticus
I. Non-Convulsive Status Epilepticus (NCSE) |
---|
i. frequent unavailability of an EEG apparatus for a prompt identification of NCSE. |
ii. variety of clinical manifestations including the wide spectrum of behavioral presentations. |
iii. the differential diagnosis of altered mental status is vast and might consequently lead to a significant under-diagnosis of NCSE. |
iv. even when an EEG device is available, EEG ictal identification of the variable EEG morphologies encountered in NCSE might require expert identification and interpretation. |
v. unavailability of a neurologist to give an emergent interpretation. |
II. Generalized Convulsive Status Epilepticus (GCSE) |
i. high correlation with various acute brain injuries. |
ii. NCSE might predominate after control of GCSE. |
iii. specific EEG patterns after control of convulsions are correlated with prognosis. |
III. Breakthrough Seizures |
i. identification of underlying cause of seizure exacerbation. |
ii. management of antiepileptic drug regimen. |
IV. Severe Traumatic Brain Injury (sTBI) |
i. "Pharmacologically" paralyzed patient where cerebral function cannot be strictly assessed clinically. |
ii. management of neurological insults that could be delayed in appearing and thus raising the risk of irreversible cerebral damage. |
iii. administration of various sedatives/analgesics that carry a high risk of sedation. |
iv. evaluation of a consequent cerebral dysfunction that is paralleled by various extra cerebral defects. |
