Abstract
previous research has been inconclusive about the nature of hemispheric asymmetry
in emotional processing.
13 patients with DSM-IV bipolar disorder received repeated QEEGs over 2 years in different
mood states. Z-score measures of asymmetry were assessed.
asymmetry in frontotemporal slow-wave activity appeared to be in opposite directions
in depression compared to mania/hypomania.
mood change in bipolar disorder is associated with change in QEEG asymmetry.
study of larger numbers of more homogenous patients under similar conditions is needed.
study of mood state-dependent asymmetry changes in bipolar disorder may lead to better
understanding of hemispheric processing of emotion.
