Abstract

The attentional capability of an individual is an evaluating factor in the assessment of mild cognitive impairment for concentration. The non-invasive recording and analysis of Electro Encephalo Gram (EEG) is a current technique in evaluation of brain cognitive activity. This paper is to bring out the prime importance of Eye Blink Rate (EBR) obtained from Electroculogram (EOG) while recording EEG for the evaluation of attentional disorder leading to cognitive impairment. Prefrontal electrodes are used to pick the EOG signal which is preprocessed for identification of eyeblinks. With the calculation of Eye Blink Rate (EBR) the cognitive impairment is classified using Support Vector Machines (SVM). Results of the experiments indicate that the classification using SVM is consistently better for the decision making of a mild cognitive impairment.
