The Epileptic seizure is one of major neurological
brain disorders and about 50 million of world’s population is
affected by it. Electroencephalography is medical test which
records brain signal by mounting electrodes on scalp or brain
cortex to diagnosis seizure. Scalp Electroencephalography has
low spatial resolution and presence of external artifact as
compared to Intracranial Electroencephalography. In
Intracranial Electroencephalography strip, grid and depth type of
electrodes are implanted on cortex of brain by surgery to measure
brain signal. Analysis of brain signal was carried out in past in
diagnosis of Epileptic seizure. Seizure classification and Severity
measurement of Epileptic Seizure are still challenging areas of
research. Seizures are classified as focal seizure, generalized and
secondary generalized seizure depending upon the area of brain
which it generates and how it spreads. Classification of seizure
helps in treatment of seizure and during brain surgery to operate
on brain part which is responsible for continuous seizures
generation. Developed seizure classification algorithm classifies
seizures as focal Seizure, generalized Seizure and secondary
generalized seizure depending on the percentage of iEEG
electrodes detecting seizure activity. Seizure severity measurement
scale is developed by modification in National Hospital Seizure
Severity Scale. Seizures are graded as Mild seizure, Moderate
seizure and severe seizure depending on its severity. Seizure
Classification and Seizure Severity Measurement improves life
quality of Epileptic patients by proper drug management.
