Abstract: In this work, a new algorithm is developed to measure the loss of consciousness degrees in normal, pre-ictal, and epileptic seizure cases using bi-spectral analysis. The study is carried out on the electroencephalogram (EEG) signals; in which 200 records are used as pre-ictal cases, and 100 records are used as epileptic cases. All these cases are compared to 100 normal cases which represent the EEG signal in relaxed and in an awake state with open eyes. The obtained results are very satisfactory and show the efficiency of the proposed algorithm. The unconsciousness degree is very low in normal cases, very high in pre-ictal cases, and varies between high to middle during epileptic seizure cases. The algorithm promising for studying the unconsciousness degree in other cases such as anaesthesia and in hypnosis cases.
