Video correlation aids in the diagnosis of epileptogenic activity and has a higher diagnostic success rate. Generally the LTEM stay lasts about 5 days and is continuous except when the patient is in the bathroom.
It is indicated in patients that have little success in terms of seizure control despite that fact that they are on antiepileptic treatments. The LTEM is used to answer the following questions.
