Intensive neurodiagnostic monitoring is useful in the diagnosis and classification of epileptic seizures and other paroxysmal disorders. The correlation of clinical/behavioral data, EEG events, and serum prolactin levels may clarify the type(s) of epileptic seizures and may distinguish epileptic seizures from non-epileptic events. Serial determinations of AED's may assist in the detection of problems with AED compliance and with drug interactions which complicate the patient's management.
