A Review on Automated Detection of Non-convulsive Seizures Using EEG

Seizures are mainly categorized as convulsive seizures and non-convulsive seizures. Diagnosis of convulsive seizures is easy due to its evident clinical manifestations. While these seizures can be the basis of neuronal damage, treatment is provided at the early stage due to its easy clinical diagnosis. On the other hand non-convulsive seizures lack convulsions. However, it too can cause neuronal damage. It can have fluctuating symptoms coupled with the mental state variation which makes the clinical diagnosis of it very difficult. Thus, it is frequently missed in patients of changed mental state. To confirm the diagnosis EEG is needed. This study gives an overview on the detection methods of non-convulsive seizures.
