Pre-treatment EEG and it's relationship to depression severity and paroxetine treatment outcome.
An array of variables have been assessed as potential early predictors of antidepressant response in depressed patients . This exploratory study examined the relationship of clinical outcome , following pharmacotherapeutic treatment , with quantitative  electroencephalographic ( EEG ) features assessed prior to treatment onset . In 70 major affective disorder patients , pre-treatment spectrum-analysed topographic EEG indices ( absolute power , relative power , mean frequency , inter-hemispheric power asymmetry and coherence for 4 frequency b and s ) were assessed in relation to baseline HAM-D ratings and HAM-D rating changes following 6 weeks of open-label paroxetine treatment .  EEG slow wave ( theta ) activities were positively correlated with depression ratings prior to treatment . Of the patients ( n = 51 ) completing treatment , 80 % evidence d a > 50 % reduction in HAM-D ratings . Improved rating changes in general were found to be negatively related to slow ( delta and theta ) wave activity and positively related to fast ( beta ) activity at frontal recording sites . Findings are discussed in relation to the neurochemistry and neurobiology of depressive disorders
