Electroencephalography of the patient. Electroencephalography (a-b) showed that low to medium wave amplitude 10-11 Hz alpha waves and alpha rhythm were seen in both occipital leads when the eyes were awake and closed, with poor amplitude and rhythm modulation and basic symmetry bilaterally. When awake and quiet, slightly more medium-wave amplitude 4-7 Hz theta waves were seen in bilateral leads, with significant anterior head, mixed with a small amount of low-wave amplitude 14-25 Hz beta waves, with basic symmetry bilaterally
