Abstract

Epilepsy is a neurological condition that affects approximately more than 50 million people around the globe, out of which the prevalence of this disease is also seen in developed countries. Epilepsy can be clinical defined by two or more non triggered seizures. A seizure can be characterized as a paroxysmal event which is caused due to hyper–synchronization in the neurons that many have various reasons of manifestation. The neuronal discharge maybe focal spreading in specific brain cortex or widespread throughout the cortex. An Electroencephalogram (EEG) is used to in diagnosis and management of epilepsy and can be used for routine examinations, it also considered to be the golden standard investigation of epileptic syndrome. While using EEG the distribution, presence and frequency of interictal epileptiform discharges IEDs are suggestive diagnosis of epilepsy. In other words the presence of IEDs in an individual’s EEG is a diagnosis of epilepsy. IEDs are predominantly found in EEG that is performed during sleep which can give basic diagnosis and prognosis of sleep related epilepsies in patients. During sleep latent interictal discharge are activated. Sleep IEDs are said to greatly affect the epilepsy management. These interaction mechanisms of sleep and epilepsies tends to bring about changes in behaviour of the seizure.
