Diagnosis of epilepsy.

ABSTRACT

Essential in the diagnosis of epilepsy are repeated seizures due to discharge of electrical activity in the brain neurons, occurring without massive provocation. It is important to differentiate between epileptic seizures from syncopal reactions, cardiac dysrhythmias, vascular causes, metabolic disturbances, and psychogenic seizures. The type of seizure should always be established. It is of utmost importance to find the primary etiology of the seizure and to clarify the role of predisposing factors and the risk for seizure recurrence. Numerous important technical advances in the last few years have been of great benefit in the examination of patients with suspected epilepsy. It is worth keeping in mind, however, that the diagnosis of epilepsy is a clinical diagnosis, and it is not proper to speak of epilepsy until the patient has had two or more epileptic seizures within a relatively short interval and without massive provocation.
