Understanding the energy, amplitude, and frequency characteristics of Alpha waves, Theta waves, Delta waves on baseline EEG in patients with psychomotor epilepsy. Methods: Analysis of energy index, frequency, and amplitude of Alpha waves, Theta waves, Delta waves on 23 patients with psychomotor epilepsy treated at the Department of Psychiatry, 103 Military Hospital. Results: The energy and amplitude of Alpha waves were the lowest, followed by the energy and amplitude of Delta waves, and the highest index was the energy and amplitude of Theta waves. The frequency of Alpha waves, Theta waves, Delta waves had a slight variation. Conclusion: The results of this study provided evidence of the Alpha, Theta, and Delta waves changes in patients with psychomotor epilepsy.
