RESULTS Following an extensive review of selected studies from the 201 articles , the studies indicate that each of the psychotropic medications review ed impact alpha , beta , delta and theta waves independently and differently from each other .
Additionally , certain medications , particularly haloperidol and valproic acid , have dissimilar results exemplified in all waveforms .
OBJECTIVES It is known that psychotropic medications have an impact on the readings found in Electroencephalogram ( EEG ) .
In the field of psychiatry , there are several psychotropics utilized by clinicians .
This review seeks to investigate all the available data for psychotropic drugs and their impact on EEG changes .
Does prior antidepressant treatment of major depression impact brain function during current treatment?
The relationship between prior antidepressant treatment and prefrontal brain functional response to subsequent treatment with antidepressant medication or placebo is unknown . Eighty-nine adults with Major Depressive Disorder ( MDD ) , characterized as antidepressant-experienced or antidepressant-naive , received one week of single-blind placebo treatment prior to eight weeks of r and omized treatment with medication ( fluoxetine or venlafaxine ; n = 47 ) or placebo ( n = 42 ) in one of three similar placebo-controlled trials . Brain function was assessed at baseline , end of placebo lead-in , and during r and omized treatment using quantitative electroencephalography ( qEEG ) . The authors assessed change in prefrontal theta-b and cordance ( PFC ) in antidepressant-experienced vs. antidepressant-naive subjects . Treatment history groups differed significantly on PFC change during the placebo lead-in even when controlling for clinical and demographic variables ( F(1,62 ) = 4.27 , p = .04 ) . As assessed in linear mixed models that examined treatment history ( antidepressant-experienced or antidepressant-naive ) , treatment assignment ( medication or placebo ) , and their interaction as predictors , treatment history also predicted PFC change during the r and omized phase of treatment even when controlling for pretreatment clinical and demographic and symptom improvement during treatment ( F(1,5o ) = 5.20 , p = .03 ) . The interaction was not significant . Post hoc analyses showed that antidepressant-experienced subjects treated with placebo showed PFC changes that did not differ from PFC changes seen in the medication group . Results suggest that prefrontal brain functional changes during treatment for MDD may differ depending upon prior treatment with antidepressant medication
