OBJECTIVE: This study assessed the quantitative electroenchephalographic (QEEG) absolute power and coherence differences between a group of @entity1 with @entity162 ( @entity162 ) and a group of @entity1 with @entity161 . We also examined the correlation between QEEG measures and family history of @entity1555 . METHOD: Using the National Institutes of Mental Health (NIMH) Global Rating Scale, we rated 18 adult inpatients with a DSM-III-R diagnosis of @entity162 for the severity of the current episode. We also collected data on the family history of the illness. This group was then matched for age, sex, and handedness with an equal number of inpatients with a DSM-III-R diagnosis of @entity161 . QEEG absolute power and coherence was calculated for the alpha bandwidth (8.0 to 12.0 Hz), assessed at 18 pairs of electrodes in both hemispheres during resting, eyes-closed condition in all the @entity1 . RESULTS: The @entity1 with @entity161 showed significantly higher coherence (P = 0.047) at 6 pairs of electrodes on the right side. The group with @entity1555 showed significantly higher power (P = 0.042) at 2 pairs of electrodes on the right side. Correlational analysis showed that QEEG measures were significantly correlated (P = 0.01) with positive family history of @entity1555 . CONCLUSION: These findings suggest that the @entity1 with @entity1555 are more disorganized in the right anterior hemisphere and that there is a significant positive correlation between the QEEG measures and the presence of family history of @entity1555 . Further studies in a larger sample are required to confirm these preliminary findings.
