A case of female patient 33 years old, the EEG recorded in open eye condition, as seen in there is relatively high theta absolute power in the parietal region with relatively reduced alpha absolute power in the fronto central areas, together with hypocoherence as regard alpha band in frontal and central areas and hypocoherence as regard beta band in frontal, central and parietal areas. Also there's increase in theta power with decrease in beta power results in high Theta beta ratio
