EEG under sleep-deprivation can increase the probability of detecting epileptiform discharges in such patients. 5, 6 However, the initial routine EEG sometimes cannot detect epileptiform activity. EEG abnormalities, which are seen as spikes, or sharp waves, spike and slow-wave complexes, polyspike, and slow-wave complexes, indicate epileptic seizures that are related to present psychiatric disorders. 4 It is often difficult to describe the clinical features and to obtain a correct diagnosis in these cases.Įlectroencephalography (EEG) is the most important diagnostic tool for investigating patients with clinically-suspected epilepsy. Psychotic disorders involve hallucinations, delusions, or disorganized speech and behavior. 3 The mood changes include an abnormally elevated or depressed mood. 4 Furthermore, some psychiatric disturbances, such as mood, anxiety, psychotic, and dissociative states, are directly caused by epileptic conditions. 3Įpilepsy is associated with an increased risk for development of psychiatric disorder. 2 Clinical presentation of epilepsy may include perceptual, behavioral, cognitive, autonomic, and psychiatric symptoms. Epileptic seizures have various manifestations and causes. Epilepsies are a variety of disorders reflecting abnormal, excessive, hypersynchronous neuronal activity that is associated with substantial structural and neurochemical changes in the brain.

1 It is not a singular disease entity or a static process. Epilepsy is usually defined as a disorder characterized by recurrent and unpredictable seizures.
