An electroencephalogram (EEG) is a common test used to help diagnose epilepsy, and to find out more about someone’s seizures. Find out about the different types of EEG test Convulsive status epilepticus is a prolonged convulsive seizure for 5 minutes or longer, or recurrent seizures one after the other without recovery in between. A cause of epilepsy is only identified in about one third of people with the disorder. Causes include structural, genetic, infectious, metabolic, and immune Epilepsy patients experience challenges in daily life due to precautions they have to take in order to cope with this condition. When a seizure occurs, it might cause injuries or endanger the life of the patients or others, especially when they are using heavy machinery, e.g., deriving cars. Studies of epilepsy often rely on electroencephalogram

The localization of the brain waves within the brain regions or lobes is further narrowed by adding electrodes, which are given numbers such as T3, T4, P3, P4. Even numbers identify electrode positions on the right side of the head, and odd numbers refer to the left side. The label "z" points to electrode sites in the midline of the head Epilepsy is one kind of life frightening and exigent intellect mayhem in which affected patients endure recurrent seizures. Large numbers of people are affected by this chaos worldwide. However, there is a lack of proper decision-making systems to predict the disease in its earlier stage. Electroencephalography (EEG) is the general clinical In addition, although seizure occurrence has been regarded as random or unpredictable for long, it has been found that seizures may occur non-randomly in complex patient-specific patterns Video-EEG monitoring is essential for the pre-surgical evaluation of patients with intractable epilepsy. Many authors have described the characteristic features of seizures arising from different brain locations [1–11]. Analysis of video recordings of seizures is usually descriptive and non-standardized in contrast to interictal/ictal EEG patterns or It also avoids the use of clinical expressions, such as “during seizure,” “between seizures,” “epileptic,” and “triphasic wave,” and classifies EEG patterns based on waveforms. In the main term 1, EEG patterns are classified according to their localization into generalized, lateralized, bilateral independent, and multifocal In many EEG-based epilepsy studies, statistical parameters have been used as features to detect seizures 51, distinguish healthy participants from epilepsy patients 52 and predict LEV treatment Considering seizure pattern morphologies, short detection delays of 10 seconds or less were observed in 5 of all 13 seizures (%) with rhythmic alpha activity, in 33 of all 96 seizures (%) with rhythmic theta activity, in 8 of all 41 seizures (%) with rhythmic delta activity, in 6 of all 31 seizures (%) with paroxysmal fast activity and in

EEG analysis of seizure patterns using visibility graphs for detection of generalized seizures. Lei Wanga,c,∗, Xi Longa,b, ∗, Johan B.A.M. Arendsa,c, Ronald M. Aartsa,b. We systematically examined trajectories from 60 seizures in an attempt to determine criteria which may be used for classifying interictal and ictal patterns. These phase-plane trajectories emphasize the presence of repetitive waves, and clearly show some phase relationships between EEG channels. It is possible to follow the progress of
